摘　　要：为获得较好的设计方案,将有限元和结构拓扑优化方法应用于数控机床设计。以减重为优化目标,利用ANSYS对数控车床床身进行了拓扑优化,并利用Pro/Mechanica对优化结果进行了动静态分析。结果表明改进后的床身结构在保持原结构的静强度和动态特性的同时比原设计方案的用料减少了12.019kg。In order to obtain a better design options, a CNC lathe was designed based on finite element method and topology optimization method, the topology optimization of the hed of CNC lathe was made by ANSYS in order to reduce its weight. The optimization results were analyzed by Pro/Mechanica. The results show that the weight of the improved CNC lathe is decreased by 12. 019 kg after the optimization when keeping its original static strength and dynamic characteristics.
