基于ANSYS Workbench的剪叉式升降台关键零件拓扑优化

摘要

Based on the theory of submodel,it translates the constraint of components in assembly into nodal displacement,analyzes its forced condition and carries out the topological optimization.Taking two floors scissor stage lift as example,it establishes the model in Solidworks and realizes the topological optimization of the pivotal component.The result shows that the method is high——precision and decreases the occupation of operational resource obviously.%基于子模型思想,将某零件在装配体中的约束转化为单元节点位移插值,单独研究该零件的受力情况,并对此零件进行拓扑优化,使其在满足强度要求的情况下优化结构.以两级剪叉式升降台为例,通过SolidWorks建立其模型,联合ANSYS Workbench对其中关键零件——连接板进行拓扑优化,优化结果表明,该方法具有很高的精度并可明显减少求解资源占用情况.
