Abstract: The 2D random road surface spectrum based on the sinusoid superposition method is built, the modified sinusoid superposition method is used to extend 2D road to 3D for providing the modeling process of 3D random road surface spectrum. The forming rule of 3D 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 3D random road file is generated. Simulation results show its availability in simulation research.

Key words: sinusoid superposition method, road spectrum, 3D road, simulation, modeling, model file
