1、前言在机床结构设计方面,因为机床结构复杂,一直到现在都单凭技术经验作一些定性的改进。但是在最近,为要满足日益提高的加工精度和加工效率的要求,精确的定量结构分析方法,已经变得非常需要了。因此,出现了结构的模型实验,实物的结构实验等等的实验方法和利用计算机的法(lump thomas法),(Recap tance)合成法等等的分析方法。有限元法属于后面的一种,现正用于分析机床的主要特性——静刚
1, Preface In machine tool structural design, because of the complicated structure of the machine tool, up to now, we have made some qualitative improvements based on technical experience alone. Recently, however, accurate quantitative structural analysis methods have become increasingly needed to meet the ever-increasing demands for machining accuracy and processing efficiency. Therefore, experimental methods of structural model experiments, physical structural experiments, and the like, and analysis methods using the computer method (lump thomas method), (Recap tance) synthesis method, and the like appear. Finite element method is one of the latter, is now used to analyze the main features of machine tools - static just
