摘　　要：讨论了应用有限元方法(FEM)进行数控机床结构部件静动态设计的原理,叙述了模型简化方法及单元类型的选择。并以龙门式加工中心的滑枕为例进行分析,研究了滑枕的静动态特性,并对滑枕的结构进行改进。Principles for carrying out the static and dynamic design, by the use of finite element method, on structural components of NC machine tools were discussed, the simplification method of model and the selection of unit type were described. Taking the ram of a gantry typed machining center as an example carried out an analysis; the static and dynamic characteristics of ram were studied, and an improvement on the structure of ram was conducted.
