基于结构和性能相似度分析函数的机械产品优化设计方法

摘要/Abstract

摘要： 从结构设计角度出发，分析了主动再制造模式下的产品服役性能要求及其关键零部件的设计需求。通过分析设计参数与服役性能的映射关系，采用支持向量机（SVM）方法构建了性能相似度分析函数。基于结构和性能相似度分析函数，提出了面向主动再制造的零部件结构优化设计方法，实现对再制造时域的优化调整。最后以叶轮零件为例，验证了所提方法的有效性和可行性。

关键词: 结构相似度, 主动再制造, 性能相似度函数, 优化设计

Abstract: Considering the structural design, the operating performance demands and key parts design requirements were analyzed in predecisional remanufacturing mode. With analyzing the mapping relationship among design parameters and operating performance, the performance similarity analysis function was established by support vector machine (SVM) method. And based on the structural and performance similarity analysis function, the optimizing design method of structure for predecisional remanufacturing was proposed to optimize and modify the remanufacturing time domains for the products. Finally, the impeller part was taken as an example to validate the effectiveness and feasibility of the proposed method.

Key words: structural similarity, predecisional remanufacturing, performance similarity function, optimization design
