前轮定位参数及其动态变化对汽车操稳性能的影响

为了确保所期望的行驶特性以及避免轮胎的过度磨损，汽车必须选取合适的前轮定位参数。这里的仿真研究结果表明：汽车的初始前轮定位参数以及其动态变化对汽车的操纵稳定性能有非常大的影响；同时可以通过合理的选择前轮初始定位参数以及合理的改变前悬架结构得到合适的动态变化特性来改善汽车的操稳性能。

The influence of front wheel alignment on controllability and stability of vehiclesc

In order to insure the suitable driving behavior and avoid tire over -wear, the car must choose correct alignment parameters of front wheel. The res ult of simulation shows that, the original alignment parameters and their dynami c change have critical effect on the driving performance of vehicles, at the sam e time ,we can improve the driving performance by reasonably choosing the origin al alignment parameters and amending the suspension geometry to achieve suitable dynamic change.
