摘要
在惯性主轴坐标系下建立了汽车整车的振动方程，它是非线性常微分方程。用精细时程积分法和摄动法求出了一定路面输入下方程的解，两种方法所求结果符合良好。分析结果表明：在一定条件下，汽车振动各自由度之间存在较强的耦合。
The vibrating equations on automobile as a whole, which are no-linear ordinary differential, are obtained in the Inertial Principal Axis System. Under certain road condition, the solutions to the vibrating equations can be foud out through the precise time-integration method and the method of perturbation, and the two results agree with each other. The results prove that there are strong coupling effects on its every degree of freedom under certain condition.
