摘　　要：针对MAX_DOAS关键转动部件蜗轮蜗杆传动存在的问题,建立了其多目标优化数学模型,利用线性加权和法将各分目标函数转化为评价函数并根据工程应用技术需求重要度确定各分目标函数权系数。利用科学计算软件求解多目标优化问题,并对一种工程应用环境下的优化结构进行分析以验证其优化结果的合理性。结果表明,优化结构很好地满足设计要求,证明了该优化方法的合理性。Focus on the problem exiting in the key rotating parts of the worm gear drive on MAX_ DOAS,the multi- objective optimization model is established,the objective functions is transformed into the evaluation function by using the linear weighted sum method. The objective functions weight coefficient is determined according to importance of demand in engineering application technology. The multi- objective optimization problem is solved and the optimization structure is analyzed to verify the reasonability of the optimization results in one kind of engineering application environment through scientific computing software. The results show that the optimized structure can achieve the design requirements,and the reasonability of the optimization method is proved.
