摘　　要：运用汽车动力学仿真软件ADAMS/Car建立整车模型,在整车设计模块中将某一具体车型在一定条件下运行,并用ADAMS/Car所提供的后处理功能对运行过程中汽车轮胎所受垂直力进行分析,最后将仿真得出的结果与实车试验所得结果在MATLAB软件中进行频谱分析。结果表明:应用ADAMS/Car所建立的模型能较全面地评价汽车动力学性能,该软件适用于汽车垂直力载荷的研究,可以为汽车动力学研究提供方便。By establishing complete vehicle model in vehicle design module of ADAMS/Car, this paper proposes a specific model under certain conditions, analyzes vertical force of automobile tires in running process by means of ADAMS/Car post-processing function, and finally makes spectrum analysis on the simulated results and test results of real vehicles in MATLAB software. The result shows that the model established can reflect well dynamics performance in ADAMS/Car, which is suitable for the vertical load research, and is helpful for vehicle dynamics research.
