摘　　要：根据谐波叠加法得到二维随机路面谱,通过改进的谐波叠加法将二维路面谱扩展到三维,形成三维随机路面谱的建模方法。详解了ADAMS中三维随机路面文件的编制规则,通过Matlab编程计算出路面文件中的路面点高程值阵列,生成ADAMS三维随机路面模型文件,仿真计算过程表明路面可用于仿真计算研究。The 2 D random road surface spectrum based on the sinusoid superposition method is built,the modified sinusoid superposition method is used to extend 2 D road to 3 D for providing the modeling process of 3 D random road surface spectrum. The forming rule of 3 D random road file in automatic dynamic analysis of mechanical system（ ADAMS） is expatiated; the altitude matrix in road file is calculated by Matlab programming and the 3 D random road file is generated. Simulation results show its availability in simulation research.
