During staff front and back push-and-pull operating rod 2, operating rod resistance system driving wheel 5 is followed operating rod 2 rotations, and under the traction of operating rod resistance system wire rope 51, operating rod resistance system spring 81,82 deforms.Simultaneously, the corner that operating rod resistance system scrambler 53 is measured operating rod 2 in real time sends to external control card, control card sends to host computer PC with signal, host computer calculates the corner of operating rod resistance system motor 11 axles and controls it and do position servo, drive 6 rotations of operating rod resistance system engaged wheel, at operating rod resistance system wire rope 51, under 61 the common traction, operating rod resistance system spring 81,82 finish certain deformation, acting on the operating rod resistance system driving wheel 52 by wire rope 51 with joint efforts of two springs, thereby make operating rod resistance system 52 be subject to certain moment of torsion, this moment of torsion is experienced feedback force by being delivered on the bearing circle 1 on the operating rod 2 when making people's push-and-pull operating rod.
The size of the feedback force of bearing circle resistance system and operating rod resistance system is adjustable.The size of the feedback force that two resistance systems produce is to be determined by separately driving wheel and the sports coupling relation of engaged wheel.Change the control algolithm of motor, can change the sports coupling relation of driving wheel and engaged wheel, adjust the size of feedback force.
In the equipment operating process, scrambler is used for the angle of direction of measurement dish or operating rod, and host computer is calculated the parameters such as the position, speed of current bearing circle or operating rod according to the angle gauge of bearing circle and operating rod, namely obtains the work at present state of equipment.PC control software calculates the corner of motor under the work at present state, and the corner size of motor has determined the feedback force size under the current state.Set the isoparametric funtcional relationship of corner, speed of corner and bearing circle or the operating rod of motor in the control software of host computer, the motor corner of work at present state is that host computer calculates according to this funtcional relationship, and sends to control card with the control electric machine rotation.If needs are adjusted the size of feedback force, only motor corner and bearing circle or operating rod corner, the isoparametric funtcional relationship of speed in the need change control software need not adjusted hardware, can adjust easily the size of feedback force.
The structural representation of pedestal and pedestal baffle plate as shown in figure 13.Pedestal 9 upper surfaces have square hole 9A, the two ends of operating rod resistance system main drive shaft 52 are installed in mounting hole 9B, the 9C of pedestal 9 both sides, each part on the axle is installed in the 9A of hole, pedestal baffle plate 91,92 is installed on the pedestal 9, in order to block the hole that pedestal 9 upper surfaces stay after each part installation on the operating rod resistance system main drive shaft 52.Be processed with some counter sink 9B on the pedestal 9, in order to aircraft steering wheel force feedback system installing and fixing in working environment.
The rotating shaft of aircraft steering wheel force feedback system bearing circle is held on the height of pedestal upper surface and the bearing circle a little with the distance of revolving shaft all according to the True Data design of certain model passenger plane of Boeing series.The present invention's simulation resistance that pilot's both hands are experienced in the aircraft handling process belongs to the force sense interactive device field.Reliable operation of the present invention, precision height, the large I of feedback force is adjusted flexibly according to user's request simultaneously.The present invention experiences for operating personnel provide the power of aircraft handling to feel, in operating process, the visual effect that shows in real time the aircraft drive simulating by display or Helmet Mounted Display for the operator, the interactive device that cooperates other, can for the operator provides the driving experience of flying comparatively really, can be used for pilot's aircraft handling training or other forms of aircraft drive simulating.
