Finally, apply sequential quadratic programming algorithm to carry on the optimization design computation to the suspension system design parameters, and obtain the design parameters when the wheel horizontal slip quantity is smallest according to the optimized result. 最后应用序列二次规划算法对悬架系统结构参数进行优化设计计算,根据优化结果得到车轮横向滑移量最小时的结构参数。
