模拟驾驶系统中动力学模型的研究与仿真

Study and emulation of dynamic models in automobile driving simulator technology

采用动力学和运动学分析方法对汽车所受的力进行研究,得出其动力学方程,从而对汽车驾驶进行仿真,并对车辆动力学仿真运动模型实验建模,将实验的数据发送给视景计算机,由其驱动视景变化,视景计算机对车辆运动进行碰撞检测,将碰撞结果反馈给主机进行所受外力的计算,由此仿真模拟驾驶系统的运动.通过实验所建立的模型基本满足模拟驾驶系统的要求.

The applied forces on automoliles during moving was studied using methods of dynamic analysis and kinematic analysis. Dynamics equations were developed. And the experiment modeling of vehicle dynamics emulation motion model was conducted. The data were sent to scene computer to drive scene moving. Collision-detecting was performed by scene computer and the results of tests were fed back to host computers. Then all moving of driving simulator can be emulated. The model found through the experiment have basically satisfied the require ments of automobile driving simulator system.
