摘　　要：用MATLAB中的实时仿真工具Simulink建模,结合频谱分析方法,研究了弹性力为非线性恢复力的两自由度汽车模型的频率响应特性,并与线性力作用下的频率特性作了比较,为解决非线性振动问题提供了一种新的方法。In this paper a double degree-of-freedom vehicle model with nonlinear restoring force is established by using the software package MATLAB/Simulink. The frequency response characteristics of this system with nonlinear and linear restoring force are studied respectively and compared. A new approach is proposed to solve the nonlinear vibration problem.
