摘要/Abstract

摘要： 针对航空发动机整体叶盘磨抛机床叶片型面砂带磨头结构的轻量化设计目标，对磨头支撑板开展变密度法拓扑优化设计.在完成磨头静动态分析的基础上，进行了变密度法拓扑优化理论分析.以磨头支撑板最优材料分布为基础，对磨头结构开展轻量化布局以及尺寸优化，获得了最终的磨头结构设计参数.结果表明，优化后磨头质量总体来说相比原始结构减轻了8.74%，并在动静力学性能方面获得了较为理想的提升，较好地实现了磨头结构减重优化设计目标.

Abstract: Aiming at the lightweight design target of the head structure of grinding and polishing machine for the blade surface grinding of aeroengine’s overall blade disk， the variable density method for topological optimization design was applied to the grinding head support plate. Based on the static and dynamic analysis of the grinding head structure， the theory of topological optimization of variable density method was studied. Based on the topologically optimized material distribution results， the lightweight structure and size optimization of the grinding head structure were carried out， and the final design parameters of the grinding head structure were obtained. The results showed that the mass of the optimized grinding head structure is reduced by 8.74%， and the dynamic and static mechanical properties of the structure are advanced， that is， the lightweight design of the grinding head structure is well achieved.

Key words: topology optimization, grinding head, lightweight design, variable density method, structural design
