摘　　要：在ADAMS/View软件环境下,建立了某工程车辆多体动力学模型,提出了随机路面的建模方法,进行了不同车速和不同随机激励输入下的车辆平顺性评价虚拟试验.通过与相同实验条件下实车平顺性道路试验结果比较,验证了该模型在评价车辆平顺性方面具有较高的精度和可信度.A multi-body dynamic model for an off-road vehicle using ADAMS/View software based on topology analysis is developed,which is followed by a further study of stochastic road model.In subsequence,virtual tests with respect to ride performance are carried out with several typical vehicle operating conditions.From the ride performance point of view,the precision of the vehicle model is verified by comparing the results from the virtual test with that from the field test.

关 键 词：车辆动力学 ADAMS/View 虚拟实验
