摘　　要：以高速立式五轴加工中心滑枕为研究对象,阐述了其初始结构设计原理,并基于静动态分析理论,采用有限元分析方法针对其进行静态和模态分析,为了进一步提高其动态特性,利用拓扑优化方法对滑枕结构进行轻量化设计,并对优化前后结构做对比分析。最终优化后的滑枕质量减轻了31%,一阶固有频率增长了22.4%。既提升了机床滑枕部件的动态性能,又实现了滑枕部件的轻量化设计。该方法为该类机床其他关键零部件及至整机优化设计奠定了基础。Taking the high-speed vertical five axis machining center ram as the research object,the initial structural design principle was elaborated.Then,based on the theory of static and dynamic analysis,finite element analysis was used to conduct static and modal analysis on it.In order to further improve its dynamic characteristics,topology optimization method was used for lightweight design of the ram structure,and a comparative analysis was conducted on the structure before and after optimization.After the final optimization,the mass of the ram was reduced by 31%,and the first-order natural frequency increased by 22.4%.This study not only improves the dynamic performance of the machine tool ram components,but also achieves lightweight design of the ram components.This method lays the foundation for the optimization design of other key components and the whole machine of this type of machine tool.
