摘　　要：采用谐波叠加法对随机路面进行数值模拟,用AR模型求取模拟出的随机路面功率谱密度并与理论功率谱密度进行比较,结果显示两者吻合很好,表明该方法可行。用MATLAB编程输出ADAMS路面文件数据,据此修改路面文件并进行整车单移线仿真。结果表明,此方法可实现整车仿真并进行性能评价。The road roughness was simulated by partial wave adding model. Comparing with the PSD given, the PSD of the road roughness simulated correspond well. The data needed by ADAMS road file was created with MATLAB, then 3D Equivalent-Volume road file was created. Single Lane Change was carried out in ADAMS, and the result showed this method doable.
