摘　　要：应用经典力学理论,将陀螺效应引入双横臂独立悬架动力学模型,结合虚拟样机的CAE仿真,量化分析了陀螺力矩对前轮摆振的影响。结果表明,调整车轮外倾角和前束角的变化率及其匹配关系,可解决陀螺效应引起的前轮摆振问题。By applying classical mechanics theory, the gyro effect is introduced into the dynamic model of double wishbone suspension,and combined with CAE simulation of virtual prototype, the effects of gyro torque on front wheel shimmy is quantitatively analyzed. The results show that through the adjustment of the changing rates of wheel camber and toe and their matching relationship,the issue of front wheel shimmy caused by gyro effect can be resolved.
