摘　　要：以某智能工厂新研制应用的高精密卧式加工中心床身阶梯导轨为研究对象,建立床身有限元模型,利用Ansys软件对该床身进行静力分析和模态分析,分析床身阶梯导轨在文中跨距和高度差时的最大变形,找出床身薄弱环节,对卧加床身的结构与尺寸优化提供理论依据,为后续分析不同导轨跨距对卧加床身的变形影响奠定基础,最终实现卧加阶梯导轨床身参数化设计。Taking the ladder guide of the high precision horizontal machining center in an intelligent factory as the research object.the finite element model of the bed is established.The static and modal analysis of the bed is carried out by using Ansys software.analysis in the article the stair of lathe bed guide rail span and height difference of the maximum deformation,find out the bed weak links.The theoretical basis of structure and dimension optimization is provided,which lays the foundation for the subsequent analysis of the influence of different guide rail spans on the deformation of bedding,and finally realizes the parametric design of bedding of bedding with ladder guide rail.
