摘要

运用多体动力学和悬架运动学理论对麦克弗森悬架进行了研究。改变下控制臂前橡胶衬套刚度时，对悬架的垂直回弹、横摇回弹、制动力和驱动力进行了分析和讨论。得出结论:在垂直弹跳和横摇弹跳中，前衬套各方向刚度对悬架性能没有影响。在制动力和驱动力中，橡胶衬套的径向刚度对悬架性能影响较大，而橡胶衬套的轴向刚度和扭转刚度对悬架性能影响较小。

Performance analysis of front rubber bushing stiffness of lower control arm on McPherson Suspension

McPherson Suspension is researched with multi-body dynamics and Suspension Kinematics theory. When the front rubber bushing stiffness of lower control arm is changed, the suspension performance is analyzed and discussed in the vertical bounce, roll bounce, brake force and drive force. The conclusion is drawn that stiffness of front rubber bushing in all directions has no effect on the suspension performance in the vertical bounce and roll bounce. In the brake force and drive force radical stiffness of rubber bushing has heavy effect on the suspension performance and axial and torsion stiffness of rubber bushing has a little effect on the suspension performance.
