摘　　要：车辆转向系统是一个复杂的系统,轮胎力的非线性使得转向系统呈现出强烈的非线性特征。建立了车辆转向系统的非线性模型,并引入了非线性动力学的思想,通过分析系统奇点的性质,研究了轮胎的几何性质以及车辆的纵向加速度对操纵稳定性的影响,在稳定条件中引入了车辆纵向加速度,深化了操纵稳定性的研究。The nonlinear model of the vehicle cornering system was established and the nonlinear dynamic analysis was introduced. Through the analysis of characters of singular points, the influences of geometrical properties of tyre and the longitudinal acceleration on the handling stability were studied.Considering the longitudinal acceleration as one of the stability conditions will deepen the study of handling stability.
