| 摘 要： | 为研究制动时汽车水平、垂直以及俯仰3个方向的耦合运动所引起的整车振动,建立了三自由度整车非线性动力学模型;通过对动力学方程进行求解和对实际参数的取值,得出具体函数,并且运用MATLAB进行仿真,得出了制动时汽车在垂直和俯仰方向的振动响应函数坐标曲线。

| Abstract: | To study the vibration of automobile in the course of applying brake,which is caused by the coupled motion of the level、vertical and pitching directions of automobile,a 3-degree of freedom non-linear model is established.The definite function is got by solving the kinetic equation and choosing the realistic parameters.The response of vibration of automobile in the vertical and pitching motion in the course of applying brake is obtained by means of MATLAB simulation. |
