Description
La présente invention a pour objet un procédé qui permet d'analyser séparément les différents paramètres de déplacement d'un cheval, pour différents objectifs et notamment pour les restituer sur un simulateur.The present invention relates to a method which makes it possible to analyze separately the different parameters of movement of a horse, for different objectives and in particular to reproduce them on a simulator.
Les techniques de simulation sont connues, en particulier en ce qui concerne les aéronefs ou les chars. Cependant, on a toujours, jusqu'à présent, calculé au moyen de modèles mathématiques la valeur à chaque instant de chacun des paramètres du mouvement de l'aéronef de façon à pouvoir reconstituer avec le plus de fidélité possible ce mouvement.Simulation techniques are known, in particular with regard to aircraft or tanks. However, up to the present time, the mathematical models have always calculated the value at each instant of each of the parameters of the movement of the aircraft so as to be able to reconstruct this movement as faithfully as possible.
Cette méthode s'est avérée difficilement inutilisable dans le cas de mouvements complexes et relativement aléatoires comme c'est le cas, par exemple pour un cheval se déplaçant au pas, au trot, au galop ou encore effectuant un franchissement d'obstacle ou des figures; parce que les lois mathématiques régissant les différents paramètres du mouvement d'un cheval sont très complexes et pratiquement impossibles à déterminer. Si même on arrivait par des approximations successives à déterminer de telles lois, on obtiendrait un mouvement théorique d'un cheval standard, ce qui n'aurait pas un grand intérêt pratique.This method has proven to be difficult to use in the case of complex and relatively random movements as is the case, for example for a horse moving at a walk, trotting, galloping or even performing obstacle clearance or figures ; because the mathematical laws governing the different parameters of a horse's movement are very complex and practically impossible to determine. If we even arrived at successive approximations to determine such laws, we would obtain a theoretical movement of a standard horse, which would not be of much practical interest.
Lorsqu'un cheval se déplace, la selle se déplace à des vitesses variables d'avant en arrière, d'un côté à l'autre, de haut en bas, c'est-à-dire selon trois axes X (longitudinal), Y (latéral) et Z (vertical) tout en effectuant des rotations selon ces trois axes : roulis, tangage, lacet.When a horse moves, the saddle moves at variable speeds from front to back, from side to side, from top to bottom, that is to say along three axes X (longitudinal), Y (lateral) and Z (vertical) while performing rotations along these three axes: roll, pitch, yaw.
Le procédé selon la présente invention consiste à :
- a- placer sur le cheval (la selle par exemple) en mouvement réel des moyens de mesure (accéléromètres, gyromètres, centrale à inertie) par l'intermédiaire desquels on mesure les vitesses de déplacement linéaire selon les trois axes X, Y, Z et éventuellement de déplacement en rotation selon ces mêmes axes ;
- b- établir à partir de ces mesures les courbes figuratives, par périodes répétitives, des variations de vitesse et de position pour les déplacements linéaires et éventuellement pour les déplacements en rotation.
- a- place on the horse (the saddle for example) in real movement measuring means (accelerometers, gyrometers, inertial unit) by means of which the linear displacement speeds are measured along the three axes X, Y, Z and possibly displacement in rotation along these same axes;
- b- from these measurements, establish the figurative curves, by repetitive periods, of speed and position variations for linear displacements and possibly for rotational displacements.
On obtient ainsi une analyse précise des paramètres du mouvement réel d'un cheval déterminé.This gives a precise analysis of the parameters of the real movement of a given horse.
On peut ainsi établir un certain nombre de groupes de courbes "variations de vitesse et de position" pour les déplacements selon les trois axes X, Y, et Z ; par exemple six groupes de telles courbes, trois pour les déplacements linéaires et trois pour les déplacements en rotation. L'analyse de ces groupes de courbes permet une analyse des paramètres les plus caractéristiques du déplacement d'un cheval déterminé se déplaçant dans des conditions déterminées.One can thus establish a certain number of groups of curves "variations of speed and position" for displacements according to the three axes X, Y, and Z; for example six groups of such curves, three for linear displacements and three for rotational displacements. The analysis of these groups of curves allows an analysis of the most characteristic parameters of the movement of a determined horse moving under determined conditions.
Il peut également être intéressant en dehors des six paramètres relatifs à l'allure (c'est-à-dire au déplacement du cheval) d'analyser d'autres paramètres particuliers au cheval tels que mouvements de l'encolure et/ou de la nuque. On procèdera alors à une étude des mouvements de l'encolure, toujours selon les mêmes axes, à savoir l'abaissement ou relèvement de l'encolure (axe de tangage Y), flexion latérale (axe de lacet Z), rotation (axe de roulis X) ainsi que des mouvements de la nuque : flexion directe (tangage), flexion latérale (lacet) rotation de la tête (roulis).It may also be interesting outside the six parameters relating to the gait (that is to say the movement of the horse) to analyze other parameters specific to the horse such as movements of the neck and / or the neck. We will then proceed to a study of the movements of the neck, always along the same axes, namely the lowering or raising of the neck (pitch axis Y), lateral bending (yaw axis Z), rotation (axis of roll X) as well as movements of the nape of the neck: direct bending (pitching), lateral bending (yaw) rotation of the head (roll).
L'examen de ces courbes, qui sont alors spécifiques à un cheval, comparées à celles d'autres chevaux permet de déterminer ses performances et ses aptitudes à différents usages. Ce même examen permet de détecter des irrégularités d'allures ou des défauts pathologiques.The examination of these curves, which are then specific to a horse, compared to those of other horses makes it possible to determine its performance and its aptitudes for different uses. This same examination makes it possible to detect irregularities in gait or pathological defects.
Ce procédé permet donc une analyse scientifique des caractéristiques du mouvement d'un cheval et de ses aptitudes beaucoup plus rigoureuse et précise que celles qui jusqu'à présent n'ont été obtenues que par la simple observation de spécialistes.This process therefore allows a scientific analysis of the characteristics of the movement of a horse and its skills much more rigorous and precise than those which until now have been obtained only by the simple observation of specialists.
Selon la présente invention, on peut, après les phases précédentes, introduire les courbes obtenues dans un modèle de calcul qui détermine, par sommation desdites courbes, les positions des vérins d'une plate-forme de simulation pour reproduire les mouvements combinés des déplacements du cheval.According to the present invention, it is possible, after the preceding phases, to introduce the curves obtained into a calculation model which determines, by summing said curves, the positions of the jacks of a simulation platform to reproduce the combined movements of the displacements of the horse.
Il existe de nombreux dispositifs de simulation plus ou moins complexes ayant un certain nombre de degrés de liberté et, en fonction de la complexité de la simulation que l'on désire obtenir on utilisera certaines des courbes ainsi déterminées ou bien toutes ces courbes.There are many more or less complex simulation devices having a certain number of degrees of freedom and, depending on the complexity of the simulation that it is desired to obtain, some of the curves thus determined will be used or all of these curves.
Par exemple on peut, pour un dispositif de simulation à 3 degrés de liberté, ne pouvant reproduire que des mouvements linéaires selon les trois axes X, Y et Z, n'employer que les courbes des déplacements linéaires.For example, it is possible, for a simulation device with 3 degrees of freedom, being able to reproduce only linear movements along the three axes X, Y and Z, using only the curves of the linear displacements.
On peut également employer une plate-forme à six degrés de liberté du type constitué de deux plate-formes triangulaires inversées, les trois sommets du triangle inférieur, servant de base, et les trois sommets du triangle supérieur étant reliés par six vérins, le volume géométrique défini par les deux triangles et les six vérins comportant huit faces triangulaires.One can also use a platform with six degrees of freedom of the type consisting of two inverted triangular platforms, the three vertices of the lower triangle serving as a base, and the three vertices of the upper triangle being connected by six jacks, the volume geometric defined by the two triangles and the six cylinders with eight triangular faces.
Dans ce cas on peut utiliser les 6 groupes de courbes caractéristiques de l'allure du cheval et le modèle de calcul détermine, par sommation de ces six courbes les positions des six vérins de la plate-forme à six degrés de libertéIn this case one can use the 6 groups of curves characteristic of the pace of the horse and the calculation model determines, by summation of these six curves the positions of the six cylinders of the platform with six degrees of freedom
On peut également n'utiliser que certaines de ces courbes. A titre d'exemple, tout en utilisant une plate-forme à 6 degrés de liberté (donc à 6 vérins) on n'a introduit dans le modèle de calcul uniquement les trois groupes de courbes de déplacements linéaires selon les axes X, Y et Z, de sorte que l'on n'a obtenu que des déplacements en translation, sans rotation, du triangle supérieur : il s'est cependant avéré, que l'on obtenait ainsi une simulation telle du mouvement du cheval qu'un cavalier expérimenté peut reconnaître sans hésitation, non seulement l'allure du cheval, mais quel est le pied caractéristique de l'allure (galop à gauche, galop à droite etc.)We can also use only some of these curves. By way of example, while using a platform with 6 degrees of freedom (therefore with 6 jacks), only the three groups of curves of linear displacements along the axes X, Y and Z, so that we obtained only translational displacements, without rotation, of the upper triangle: it turned out, however, that we thus obtained such a simulation of the movement of the horse as an experienced rider can recognize without hesitation, not only the gait of the horse, but what is the characteristic foot of the gait (gallop on the left, gallop on the right etc.)
Le cavalier, qui monte un cheval subit une succession d'accélérations positives et négatives plusieurs fois par seconde en fonction de chaque allure du cheval.The rider, who rides a horse undergoes a succession of positive and negative accelerations several times per second depending on each pace of the horse.
Selon un premier mode de mise en oeuvre du procédé selon l'invention on a placé sur le dos d'un cheval (soit sur le pommeau de la selle quand il y avait un cavalier, soit sur un surfaix quand il n'y en avait pas) trois accéléromètres disposés orthogonalement selon les 3 axes X,Y,et Z. On a ainsi obtenu un ensemble de mesures dont on a déduit les courbes de variations de vitesse de déplacement linéaire selon les trois axes.According to a first mode of implementation of the method according to the invention, one placed on the back of a horse (either on the pommel of the saddle when there was a rider, or on a surfaix when there was none step) three accelerometers arranged orthogonally along the 3 axes X, Y, and Z. We thus obtained a set of measurements from which we deduced the curves of variations in linear movement speed along the three axes.
Les figures 1, 2 et 3 représentent trois enregistrements selon l'axe vertical Z, au pas (figure 1) au trot (figure 2) et au galop (figure 3). Ces trois enregistrements montrent l'évolution dans le temps (1/25 de seconde) de l'accélération mesurée en 1/10 de G pour les figures 2 et 3 et au 1/100 de G pour la figure 1. L'examen de ces figures montre que les signaux sont très lisibles et sont caractéristiques de chaque allure : par exemple on voit la complexité du pas (figures 1), qui comporte trois pics positifs et négatifs pour chacune des demi-foulées. Le dépouillement de ces données donne lieu ensuite à une double intégration qui permet de calculer la vitesse et les déplacements (autour d'une position moyenne) et à une analyse par séries de FOURRIER qui permet de distinguer, dans ce phénomène périodique, la fondamentale et les harmoniques donc de le ramener à une superposition de phénomènes sinusoïdaux.Figures 1, 2 and 3 show three recordings along the vertical axis Z, in step (Figure 1) trotting (Figure 2) and galloping (Figure 3). These three recordings show the evolution over time (1/25 of a second) of the acceleration measured in 1/10 of G for Figures 2 and 3 and 1/100 of G for Figure 1. Examination of these figures shows that the signals are very legible and are characteristic of each gait: for example, we can see the complexity of the step (Figures 1 ), which has three positive and negative peaks for each of the half-strides. The analysis of these data then gives rise to a double integration which makes it possible to calculate the speed and the displacements (around an average position) and to an analysis by series of FOURRIER which makes it possible to distinguish, in this periodic phenomenon, the fundamental and harmonics therefore bring it back to a superposition of sinusoidal phenomena.
Les figures 4 et 5 montrent l'enregistrement selon l'axe des Z de deux chevaux différents, la figure 4 (qui correspond à la figure 3) étant celle d'un cheval A et la figure 5 celle d'un cheval B. L'examen de ces courbes montre qui si elles sont bien toutes deux significatives du galop, elles sont très différentes selon les deux chevaux.Figures 4 and 5 show the recording along the Z axis of two different horses, Figure 4 (which corresponds to Figure 3) being that of a horse A and Figure 5 that of a horse B. L 'examination of these curves shows that if they are both significant of the gallop, they are very different according to the two horses.
Selon un deuxième mode de mise en oeuvre du procédé selon l'invention on a placé sur le dos du cheval, et cette fois sans cavalier, une centrale à inertie . On a ainsi pu obtenir simultanément les mesures d'accélérations et de variations de vitesse en déplacement linéaire et en rotation selon les trois axes ainsi que la trajectoire suivie par le cheval.According to a second embodiment of the method according to the invention, an inertial unit has been placed on the horse's back, and this time without a rider. It was thus possible to simultaneously obtain the measurements of accelerations and variations in speed in linear displacement and in rotation along the three axes as well as the trajectory followed by the horse.
Le procédé selon l'invention consiste également, à modifier à volonté, l'une ou l'autre de ces courbes de sorte que l'on peut à volonté modifier le mouvement de la plate-forme du simulateur.The method according to the invention also consists in modifying one or other of these curves at will so that the movement of the platform of the simulator can be modified at will.
Par exemple, ayant mis en mémoire dans un calculateur les courbes correspondant aux déplacements linéaires du pas, celles correspondant au trot, celles correspondant au galop et celles correspondant au saut, on a fait apparaître bout à bout sur un écran les courbes des déplacements selon l'axe des X pour le galop et le saut et ensuite on les a reliées les unes aux autres ; on a fait de même pour les courbes selon l'axe des Y et l'axe des Z : on a ainsi obtenu la simulation du mouvement d'un cheval effectuant un saut à partir de l'allure du galop. On pourrait en opérant de la même façon simuler le mouvement d'un cheval effectuant un saut à partir du trot.For example, having stored in a computer the curves corresponding to the linear displacements of the step, those corresponding to the trot, those corresponding to the gallop and those corresponding to the jump, we did appear end to end on a screen the curves of the displacements along the X axis for the gallop and the jump and then we linked them to each other; we did the same for the curves along the Y axis and the Z axis: we thus obtained the simulation of the movement of a horse performing a jump from the pace of the gallop. By operating in the same way, we could simulate the movement of a horse jumping from the trot.
On peut donc grâce à ce procédé modifier à volonté les courbes représentatives des divers paramètres de déplacement du cheval et en conséquence la simulation du mouvement ce qui présente des avantages considérables.Thanks to this process, it is therefore possible to modify at will the curves representative of the various displacement parameters of the horse and consequently the simulation of the movement, which has considerable advantages.
Ainsi le trot d'un cheval comporte environ 130 battements à la minute ce qui est physiquement assez difficile a supporter notamment pour un adulte (sauf évidemment pour un cavalier entrainé). Il est possible grâce au procédé selon l'invention de restituer un trot confortable à 60 battements à la minute et augmenter progressivement jusqu'à 130 en fonction de la progression du cavalier : il est évident que cela présente un grand intérêt pour la formation et la sécurité de ce dernier.Thus the trotting of a horse comprises approximately 130 beats per minute which is physically quite difficult to bear in particular for an adult (except obviously for a trained rider). It is possible thanks to the method according to the invention to restore a comfortable trot at 60 beats per minute and gradually increase to 130 depending on the progress of the rider: it is obvious that this is of great interest for training and security of the latter.
De même on peut augmenter l'amplitude et diminuer la cadence qui permet de mieux faire percevoir au cavalier le mouvement caractéristique de l'allure.Likewise, the amplitude can be increased and the cadence reduced, which allows the rider to better perceive the movement characteristic of the pace.
En ce qui concerne le problème particulier du saut d'obstacle : il est évident que pour des questions de santé on est obligé de limiter le nombre de sauts à faire exécuter à un cheval au cours d'une séance d'entraînement. Par contre si le cavalier veut effectuer 90 sauts (par exemple) en une séance de travail pour s'entraîner : à apprécier le point de battue optimum en fonction d'un obstacle ou d'un parcours, à apprécier le train utile d'un parcours, à recréer des situations difficiles, il pourra le faire sur le simulateur.Regarding the particular problem of show jumping: it is obvious that for health reasons we are obliged to limit the number of jumps to make a horse perform during a training session. On the other hand if the rider wants to perform 90 jumps (for example) in a work session to train: to assess the optimum beat point according to an obstacle or a course, to appreciate the useful train of a course, to recreate difficult situations, he can do it on the simulator.
On peut également développer ainsi l'endurance d'un cavalier.We can also develop the endurance of a rider.
Ce procédé est particulièrement utile pour la rééducation par l'équitation des handicapés physiques et moteur : en réduisant cadence et amplitude on permet une meilleure adaptation aux difficultés posées par l'équitation. De même il peut être très bénéfique de faire ressentir au personnel médical telle ou telle sensation par décomposition, ralentissement ou augmentation de l'amplitude.This process is particularly useful for rehabilitation by horse riding for the physically and motor handicapped: by reducing cadence and amplitude we allow a better adaptation to the difficulties posed by horse riding. Likewise, it can be very beneficial to make medical personnel feel such or such sensation by decomposition, slowing down or increase in amplitude.
Grâce à ce procédé il est possible pour un cheval déterminé d'enregistrer des phénomènes de pathologie d'allure, donc de concourir à la détection précoce et à l'identification des irrégularités et des boiteries. Ou encore après une phase d'analyse systématique des enregistrements des allures de chevaux performants en compétition, de définir le profil idéal d'un cheval de compétition, pour les différentes disciplines de l'équitation.Thanks to this process it is possible for a determined horse to record phenomena of pathology of pace, therefore to contribute to the early detection and identification of irregularities and lameness. Or even after a phase of systematic analysis of the recordings of the gaits of horses performing in competition, to define the ideal profile of a competition horse, for the different disciplines of equitation.
Il s'avère que la restitution des sensations au cavalier par un simulateur peut impliquer une altération soit en amplitude soit en cadence de certains paramètres : il est possible d'y remédier grâce au procédé selon l'invention puisqu'il est possible de modifier à volonté chacune des courbes.It turns out that the restitution of sensations to the rider by a simulator can involve alteration either in amplitude or in cadence of certain parameters: it is possible to remedy it using the method according to the invention since it is possible to modify will each of the curves.
Dans les différents exemples, on a cité le cas des différentes allures (pas, trot, galop), l'invention est applicable bien sur non seulement aux déplacements en ligne droite mais également aux cas des figures.In the various examples, the case of the different gaits (steps, trots, gallops) has been cited, the invention is of course applicable not only to movements in a straight line but also to the cases of the figures.
Dans l'exemple donné précédemment on a décrit le cas où les modifications des courbes issues des enregistrements étaient réalisées par raccordement après visualisation. On peut également au moyen de plusieurs curseurs, agir sur la cadence ou les amplitudes.In the example given above, the case has been described where the modifications of the curves resulting from the recordings were carried out by connection after visualization. It is also possible by means of several sliders, to act on the cadence or the amplitudes.
Selon la présente invention on dispose sur le simulateur des générateurs de signaux qui agissent sur le déroulement de la simulation. Ainsi par exemple on place à niveau des genoux du cavalier et sous le selle des capteurs de pression de sorte que lorsque le cavalier presse les genoux ou bien joue de son assiette cela agit sur le déroulement des courbes dans le module de commande du simulateur (plus ou moins vite selon la pression). De même on place des capteurs sur le mors de sorte que lorsque le cavalier exerce une tension sur les rênes cela agit sur le déroulement des courbes dans le module de commande ; les deux signaux pouvant évidemment être superposés. Il est ainsi possible d'avoir une action du cavalier sur le déroulement de la simulation qui n'est plus seulement passive mais interactive.According to the present invention there are signal generators on the simulator which act on the course of the simulation. Thus, for example, pressure sensors are placed at the level of the rider's knees and under the saddle so that when the rider presses his knees or plays his plate, this acts on the course of the curves in the simulator control module (more or slower depending on the pressure). Similarly, sensors are placed on the jaw so that when the rider exerts tension on the reins, this acts on the course of the curves in the control module; the two signals can obviously be superimposed. It is thus possible to have an action of the rider on the course of the simulation which is no longer only passive but interactive.
