摘　　要：本文以轮胎与路面之间的滑移速度为出发点,在稳态指数统一模型的基础上,建立了轮胎非稳态转向特性非线性仿真模型。在实验研究中,发现了动态过程回正力臂和附加的回正力矩的滞后特性。仿真结果和试验结果对比表明,该模型足以反映轮胎非线性转向特性,可用于前轮摆振及汽车操纵动力学仿真方面的研究。A non linear tire simulation model of non steady state cornering properties is established based on the unified steady state tire model, associated with the effective slip velocity between tire tread and the road surface. The lag properties of the aligning arm of force and the addition aligning moment are introduced. The comparison of simulation results with test results shows that the model well reflect the non-linear cornering properties of the tire. The model can be applied to the studies of vehicles dynamic and front wheel shimmy.
