摘　　要：为解决传统优化设计方法中存在的最优解的函数值波动过大且容易违反约束的问题,将稳健设计运用于汽车断开式转向梯形机构的优化设计中。首先分别分析了稳健设计和转向机构的数学模型;其次在目标函数与约束中同时考虑运动副间隙的影响,建立了稳健优化设计模型。实例分析表明,与传统的优化方法相比较,该模型不仅可以得到较小的误差还具有较高的稳健性。研究结果表明,该方法有较好的可行性与实用性。In order to solve the problems of the great fluctuations and constraints dissatisfied in optimal solutions,robust design was applied to the vehicle divided steering linkage optimization.The mathematical model of the robust design and steering mechanism was analyzed.A robust model was established by considering the kinematic pair clearance both in the objective functions and constrains.Compared to traditional optimization methods,the model can get not only smaller deviation but also higher robustness.The result shows that this method is practical and effective.
