摘要
分析了电动机的转动惯量、转矩传感器刚度、减速机构减速比对汽车操纵稳定性的影响,采用汽车操纵稳定性评价指标确定目标函数,利用遗传算法对电动助力转向系统结构参数进行了优化,并对参数优化前后系统性能进行仿真对比。
This article analyses the influence of inertia, stiffness of torque sensor and reduction ratio of decelerating mechanism on the controlling stability of vehicles. Objective function is established adopting the vehicle controlling stability evaluation index. Optimization of structure parameter for EPS is carried on based on genetic algorithms, and simulation comparison is made about the system performance between the systems with and without the optimized parameters.
