摘　　要：通过仿真分析表征轮胎力学特性的影响因子对轮胎力学特性和汽车操纵稳定性的影响,提出基于蛇形试验和稳态回转试验的汽车操纵稳定性评分方法,同时对仿真结果的正确性进行验证。结果表明,侧偏刚度和摩擦因数对汽车操纵稳定性影响较大,合理增大侧偏刚度比例因子和摩擦因数比例因子可以提高汽车操纵稳定性。该仿真分析方法操作简单且具有较高的准确性,在轮胎力学特性研究和汽车操纵稳定性分析评价方面具有指导意义。The effects of influential factors on the tire mechanical characteristics and handling stability of vehicle were analyzed through simulation. An evaluation method of handling stability of vehicle based on the serpentine test and steady-state rotation test was proposed,and the simulation results were verified.The results showed that,the lateral stiffness and friction coefficient had significant impact on the handling stability of vehicle,which could be improved by appropriately increasing the scale factors of lateral stiffness and friction coefficient. The simulation analysis method was easy to operate and had high accuracy,which had guiding significance in the study of tire mechanical characteristics and evaluation of the handling stability of vehicle.
