摘　　要：以螺旋弹簧的给定刚度变化最小、自振频率最大和质量最小为设计目标,综合考虑优化设计中的随机因素,建立了基于稳健性的多目标优化模型,并在科学计算语言MATLAB中编程求解.通过液压阀螺旋弹簧设计实例的分析说明,多目标稳健优化设计提高了设计目标的稳健性,一定程度上提升了液压阀的动态响应特性.A mathematical model of multi-objective optimal design based on robust was established in order to find the least change spring＇ s stiffness, maximal inherent frequency and minimal spring mass. Random factors in the optimal design were considered syn- thetically. The mathematical model was compiled into a programmer and computed into the result in MATLAB. A hydraulic valve spiral spring design example shows that the designed target can be improved by multi-objective robust optimal design and the dynamic response characteristics of the hydraulic valve were enhanced in a certain extent.
