汽车操纵稳定性虚拟仿真研究

Study on Vehicle Handling Stability Virtual Simluation

基于汽车操纵动力学理论建立了汽车动力学模型,利用虚拟仿真技术,以ZK6100H客车为仿真对象、VC++为平台开发了汽车操纵稳定性虚拟仿真系统,并以转向盘角阶跃输入试验为例进行了仿真分析。该系统还可以对转向盘角脉冲试验、稳态转向特性试验和单移线试验进行虚拟仿真分析。本研究的完成使得在计算机上进行车辆操纵稳定性的试验模拟及评价分析成为了可能。

Based on the vehicle handling dynamics theory, a vehicle dynamics model was built. By using virtual reality technique, and using bus ZK6100H as the simulation object, and VC ＋＋ as a platform, vehicle handling and stability virtual simulation system is developed and steering wheel angle step input test is taken as an example to do the simulation analysis. This system can also make virtual simulation in the steering wheel angle step input test, stable steering characteristic test and single moving line test. The results show that the simulation of the stability test, evaluation and analysis can be manipulated on a computer, and virtual simulation will be a new means of vehicle performance simulation.
