Abstract
Description
Schingungsdämpfung am Ski durch Gegenschwingsystem mit Energie-Vibration damping on the ski through a counter-vibration system with energy
vernichtung Die Erfindung bezieht sich auf eine zusätzliche Schwingungsdompfung, die am Ski angebracht oder eingebaut wird.annihilation The invention relates to an additional vibration damping, which is attached to or built into the ski.
Der Ski herkömmlicher Art muß aus Steifigkeits und Festigkeitsgründen ziehmlich steif gebaut werden, um das nötige Torsions- und Biegemoment aufzubringen.The ski of the conventional type must for reasons of rigidity and strength be built to be fairly stiff in order to apply the necessary torsional and bending moment.
Das zieht den Nachteil nach sich, daß der Ski als elastischer Körper zum Stoß- und Schwingungsübertreger und vom eigenem Schwingungsverhalten her zum Resonanzkörper wird.This has the disadvantage that the ski is an elastic body to the shock and vibration transmitter and from its own vibration behavior to the Is a sound box.
Aufgabe der Erfindung ist es, die sowohl für das Fahrverhalten als auch für die Lebensdauer negative Auswirkung der Schwinunten zu eleminieren, d.h. die durch die Unebenheit der Piste auf den Uki übertragene Schwingungsenergie mittels eines Schwingungstilgers zu absorbieren.The object of the invention is that both for the driving behavior also to eliminate the negative impact of the Schwinunten for the service life, i.e. the vibration energy transmitted to the Uki by the unevenness of the slope by means of to absorb a vibration damper.
Diese Aufgabe wird dadurch gelöst, daß nahe der Skischaufel, also da wo sowohl Vertikal-, Longitudinal- als auch Torsionsschwingungen erzeugt werden, ein SchwingungsdCmpfer aufgesetzt wird, der nach folgendem Prinzip arbeitet.This object is achieved in that near the ski shovel, so where both vertical, longitudinal and torsional vibrations are generated, a vibration damper is put on, which works according to the following principle.
Es wird am Ski, den man zur Vereinfachung als einseitig eingespanntes Federblatt ansehen kann, auf dem frei schwingenden Ende, also nahe der Schaufel eine tasse angebracht, die über Federelemente mit dem Ski verbunden ist und dort durch die Unebenheit der Piste verursachte Schwingungsenergie aufnimmt und diese mittels Dämpfung vernichtet.It is on the ski, which for simplicity is called a one-sided clamp Can see spring leaf, on the free swinging end, so near the shovel a cup attached, which is connected to the ski via spring elements and there absorbs vibration energy caused by the unevenness of the slope and this destroyed by damping.
Dh. die Masse, die mittels der Federelemente in allen Achsen beweglich ist, nimmt die Schwingungen des Skis auf, transformiert diese in niedrigere Frequenzen und größere Amplituden irreversibel und setzt diese Schwingungen mittels einer Dämpfungsmasse, das ist ein gegen einen Wiederstand verdrängbares Medium, durch Deformationsarbeit in W-rme um.Ie. the mass, which is movable in all axes by means of the spring elements absorbs the vibrations of the ski and transforms them into lower frequencies and larger amplitudes irreversibly and sets these oscillations by means of a damping mass, this is a medium that can be displaced against resistance, through deformation work in warmth.
Es wird also dem Sch'inungsstem Ski ein zweites Schwingsystem entgegengesetzt, das ersterem die Schwingungsenergie irreversibel entzieht, indem es die ursprüngliche Schwingung in Frequenz und Amplitude verändert und über Dsmpfungsmedien vernichtet.A second oscillation system is opposed to the Sch'inungsstem ski, the former irreversibly withdraws the vibrational energy by removing the original Vibration changed in frequency and amplitude and destroyed via damping media.
Anhand beiligender Zeichnungen Fig. 1, Fig 2 und Fig. 3 wird die Erfindung näher erlautert.The invention will be explained with reference to the accompanying drawings, FIGS. 1, 2 and 3 explained in more detail.
