摘要
根据某车型硬点参数,建立后多连杆独立悬架模型。运用多体动力学和悬架系统运动学理论,在车轮跳动和制动力两种工况下,分析并讨论减震器下橡胶衬套的轴向刚度、扭转刚度和径向刚度变化对车轮定位参数及悬架性能的影响。分析可知:减震器下橡胶衬套的轴向和径向刚度对车轮定位参数及悬架影响不大,但是扭转刚度对车轮定位参数和悬架性能影响较大。
First,the model of Multi-link independent suspension is built according to hard point parameters of a car.After the button rubber bush stiffness of the damper is changed,the suspension performance is analyzed and discussed with multi-body dynamics and Suspension Kinematics theory.The conclusion is drawn that axial and radical stiffness of rubber bush has a little effect on the suspension performance,but torsion stiffness of rubber bush has heavy effect on the suspension performance.
