摘要
为解决立式数控插齿机中床身的拓扑优化结果在工程上加工制造困难的问题,建立了带有制造工艺约束的拓扑优化模型,采用OptiStruct对中床身进行拓扑优化设计,得到了约束条件含有体积分数及同时含有体积分数和制造工艺的2种拓扑优化结果.对比分析了2种拓扑优化结果,表明基于制造工艺约束的拓扑优化设计的中床身结构有更好的铸造性能.
To solve the difficulity of transforming a topology optimization design proposal of a mid-bed of vertical computer numerical control gear shaping machine tool to a manufacturable design in engineering,topology optimization model with manufacturing constraints was established.Topology optimization for mid-bed was conducted on OptiStruct package.Two topology optimization results of volume fraction constraints and volume fraction with manufacturing constraints were obtained.Comparing and analyzing the topology optimization results of two constraints,the optimal design shows that the mid-bed structure based on topology optimization with manufacturing constraints has a better castibility.
