摘  要:
建立了垂向车辆动力学模型和道路虚拟输入模型。在虚拟激励法的基础上,提出了车辆系统在随机激励下的响应的一个简便实用解法。并以简化车辆模型为例,考察了车轮动载荷计算问题,验证了该方法的有效性。

摘  要:
The vertical model for vehicle dynamics and the virtual model for road input are deduced.Based on the pseudo excitation method(PEM),a simple and convenient algorithm is suggested for obtaining the road-induced random(response) of a time-invariable vehicle system.As an illustrative example,the road-induced random response of a quarter-car model is explored in detail.The results verify that the algorithm presented here is effective for vehicle dynamic loads(calculation.)
