摘 要: | 为了探究前轮摆振的影响因素,将运动副间隙处的干摩擦等效到前轮主销处.应用拉格朗日方程建立了3自由度摆振系统模型,并用Matlab对其进行了仿真计算。结果表明,汽车在较大的初始激励下才会激发摆振;较大的干摩擦力矩有利于抑制摆振。

Abstract: | In order to explore the effection factor of front wheel shimmy,equivalent dry friction of kinematic clearance to front wheel king pin,using Lagrangke's equation to set up three freedom degree vibration model, and use Matlab to do simulation calculation.The simulation result shows,automotive can inspire vibration under initial exatition,larger dry friction torque is helpful for shimmy inhibition. |

Keywords: | shimmy initial exatition dry friction torque multi limit cycle |
