摘要
建立了垂向汽车动力学模型和道路虚拟输入模型。在精细时程积分法和虚拟激励法的基础上,提出了时不变线性汽车系统在演变随机激励下的响应的一个简便实用解法。并以简化汽车模型为例,考察了变速行驶时的平顺性问题,验证了该方法的有效性。
The vertical model of vehicle dynamics and the virtual model of road input are deduced. Based on the finer integration method in time domain and the virtual excitation method, a simple and convenient algorithm is suggested for obtaining the road induced evolutionary random response of a time-invariable vehicle system. As an illustrative example, the road induced random response of a quarter-car model is explored. The results verified that the present algorithm is effective.
