摘　　要：利用UG软件的相关参数化设计方法和用户定义特征建立活塞连杆组件的参数化模型。计算活塞所承受的载荷,采用UG NX软件中的Structure模块进行有限元分析与优化,优化器选择Altair的HyperOpt。以减轻质量为目标,快速方便地完成活塞的有限元分析与优化。Parametric model of piston and connecting rod is created by associative parametric design method and user deigned feature of UG. Load of Piston is calculated,finite element analysis and optimize design are done based on Structure of UG NX. Solver is HyperOpt of Altair. Finite element analysis and optimize design based on the weight reducing is quickly and conveniently completed.

关 键 词：相关参数化 有限元分析 优化 活塞
