摘　　要：将高速动车组齿轮箱体积作为目标函数,利用灵敏度分析法分析约束函数对不确定因素的波动情况,选出最大波动函数为附加目标函数,使高速动车组齿轮箱体积及实现约束函数对不确定因素的最大波动同时达到最小,进而缩小齿轮箱体积的波动范围,利用物理规划法将双目标函数转化为单目标函数进行优化计算.算例表明,稳健优化设计方法能使齿轮箱体积达到稳健优化目的,并为动车组其它零部件的稳健优化设计提供参考.The volume of high-speed EMU gearbox is defined as an objective function. The fluctuation of its constraint functions to the uncertain factors is analyzed by sensitivity analysis method, and the maximum fluc- tuation of sensitivity function from them to be as an additional objective function is chosen. The volume of high-speed EMU gearbox and the maximum fluctuation of constraint functions to the uncertain factors are a- chieved the minimum at the same time. In doing this, the fluctuation range of the gearbox volume is reduced. The dual objective functions are converted into a single objective function by physical programming method. The example shows that the robust optimization design method can make the of robustness and provides a theoretical basis for the development of EMU gearbox volume to achieve the goal components in the future.
