摘　　要：针对研磨机下磨盘组合件因摩擦生热导致铜盘表面热变形。基于有限元法对下磨盘组合件热-结构耦合分析,研究温度场对下磨盘组合件热变形的影响,优化下磨盘组合件的结构。简化下磨盘组合件结构建立热-结构物理模型,根据工作参数设定边界条件并求解。数值仿真结果表明:热载荷、压力载荷共同作用下,下磨盘组合件的最大位移发生在铜盘外沿表面,最大值为0.0505 mm。基于仿真结果优化下磨盘组合件结构,保证下磨盘组合件工况下平面度要求;同时,优化后下磨盘组合件重量由851.3 kg减轻至802.9 kg,节约材料6%,为研磨机下磨盘组合件改进提供了参考依据。Friction causes heat deformation of lower grinding disc. To solve this problem, finite element method is used inthe therm al-structural coupling analysis of the grinding disc assembly. We study the influence of temperature on heatdeformation, and optimize the structure of the grinding disc assembly. The thermal - structural physical model of grindingdisc assembly is simplified. The boundary condition is set according to the operating parameters. The results indicate thatthe maximum deformation displacement occurs on outer edge surface of copper disc under the heat and pressure load.And the maximum displacement is 0.0505mm. Based on simulation results, the structure of lower grinding disc isoptimized to ensure the flatness requirements of grinding disc assembly. Also the weight of grinding disc assembly isreduced from 851.3kg to 802.9kg which can save 6% material. This study provides the reference for structureoptimization of lower grinding disc assembly.
