摘要
根据WT700数控铣齿机的结构和承载特点,建立了有限元模型,并进行了典型载荷工况下的静态分析和动态分析。分析薄弱部件为滑枕,通过折衷规划法对滑枕拓扑优化,构建滑枕的概念模型,简化出滑枕的元结构,得到静动态性能双优的结构。在保证静动态性能基本不变的前提下实现滑枕结构轻量化。试验结果显示滑枕质量减少18.75%。
According to the structure and bearing characteristics of the WT700 CNC gear milling machine,the finite element model is established,the static and dynamic analyses of typical load case are carried out.The weak part is ram,the topology optimization of ram is achieved by compromise programming method,and the conceptual model of the ram is constructed.The meta structure of the ram is simplified,and the structure with excellent static and dynamic performance is obtained.The lightweight of ram structure is realized on the premise of keeping static and dynamic performance unchanged,and the experimental results show that the mass of ram is reduced by 18.75%.
