摘　　要：文章主要研究轮胎侧偏刚度特性对整车操纵稳定性的影响。通过在仿真模型中改变轮胎侧偏刚度的值,研究后轴等效侧偏角、整车不足转向、整车横摆响应频率、整车稳定性、整车响应、转向回正的等操纵稳定性指标的变化趋势及变化量大小,进而指导整车操纵稳定性设计。This paper mainly studies the influence of tire lateral stiffness characteristics on vehicle handling stability. Bychanging the value of the tire cornering stiffness in the simulation model, the stability of the rear axle equivalent side angle,the vehicle understeer, the vehicle yaw response frequency, the vehicle stability, the vehicle response, and the steering returnare studied. The trend of the indicators and the amount of change, and then guide the design of vehicle handling stability.
