摘　　要：以某地铁扶手安装座为研究对象,运用公差稳健设计方法和模糊理论对地铁扶手安装座装配尺寸链进行优化设计。基于公差稳健设计与模糊理论,建立地铁扶手安装座的公差-成本模型。通过遗传算法计算出不同模糊损失率下的地铁扶手安装座公差及成本。当模糊损失率不再降低时,达到地铁扶手安装座装配尺寸链的模糊质量损失成本最低的目的,同时,采用该方法提高了地铁扶手安装座装配尺寸链的稳健性,为地铁扶手的优化设计提供了新思路。An application of the robust tolerance design and the fuzzy theory in merto car handrails＇ mounting as-sembly dimension chain optimization design was presented herein. The robust tolerance design and fuzzy theorywere used to set a cost-tolerance model. It calculated the cost and tolerance of merto car handrails＇ mounting inthe different rate of fuzzy quality loss on genetic algorithm. It reduced the cost of the merto car handrails＇ mount-ing assembly dimension chain and increased the robustness of the merto car handrails＇ mounting assembly dimen-sion chain in the rate of fuzzy quality loss. It provides a new idea for the design of the merto car handrails.
