摘要
根据简化的2自由度随动转向力学模型,建立了动力学微分方程。分析了车速、整车质量、转动惯量和轮胎侧偏刚度对车辆随动转向稳定性的影响。通过对某轿车后桥随动转向的仿真计算与分析,验证了所得方法的正确性,为改善车辆的操纵稳定性提供了理论依据。
On the basis of the simplified mechanics model of the two degree of free-domed following-up steering the kinetics differential equation was established. The influence of car speed, mass of entire car, moment of inertia and tire lateral leaning stiffness on the stability of vehicle following-up steering was analyzed. The correctness of the obtained method was validated by means of simulative calculation and analysis on the following-up steering of certain car rear axle, thus a theoretical basis was provided for improving the manipulation stability of the vehicle.
