摘　　要：应用机械系统分析软件 ADAMS建模研究整车非线性随机振动 ,模型的自由度达 1 997个。利用伪白噪声法产生伪随机序列模拟路面不平度 ;利用 BEAM梁建立了钢板弹簧主副簧仿真模型 ,讨论了主副簧约束问题。By means of mechanical system simulation software ADAMS(Automatic Dynamic of Mechanical System), a model with 1997 DOF for a full vehicle has been found, and the nonlinear random vibration of the vehicle has been studied. The paper mainly focuses on two aspects, Simulating random irregularities of the road by pseudo-white noise method, Utilizing Beam theory to build main and assistant leaf spring model and discussing the constrain problems.
