摘 要：
在正弦波叠加模型的基础上进行了随机路面谱的计算机模拟。从空间路面频率谱出发给出了模拟随机路面谱的方法。利用Matlab软件编制了生成任意等级三维随机路面谱的程序。最后结合多体动力学仿真软件ADAMS的虚拟样机技术对生成的随机路面谱进行了分析和讨论。结果表明,该随机路面谱的计算机模拟能够更便捷的结合相关的软件进行汽车性能的分析和评价。

摘 要：
The computer simulation on stochastic road irregularities is performed based on the sinusoid superposition method. The procedure for deriving the stochastic road irregularities is given with the application of space frequency domain road model. The stochastic road irregularities are generated by the program coded by Matlab software. Finally, the stochastic road irregularities are carried out by exporting it to the virtual prototype technique software ADAMS for evaluating the performance of vehicles. It is shown from the results that the process for analyzing and evaluating the characteristics of vehicles becomes more convenient with the application of the generated stochastic road irregularities.
