用有限单元法计算机床构件的刚度已日趋成熟,国外六十年代就开始了这方面的研究,七十年代初形成通用计算程序,并通过推广应用而不断完善,国内,西安交通大学用薄壁梁有限元法、大连工学院用空间平板组合结构的有限元法计算机床构件刚度均有较大进展。但是,无论使用结构分析通用程序,还是应用专用程序进行计算,都有如下缺点:工作量大、辅助工作(如单元划分、数据编制等)复杂,受计算手段(需大、中型计算机)限制,计算成本高等。对于计算精度要求不高的初步设计,这些缺点愈加显得突出。
The finite element method to calculate the rigidity of the machine tool components has matured. In the 1960s, this research began. In the early 1970s, a generalized calculation program was formed and it was continuously popularized and popularized. At home and abroad, Xi’an Jiaotong University Yuan law, Dalian Institute of Technology with flat-panel structure of the finite element method to calculate the stiffness of machine tools have made great progress. However, no matter whether the general program of structural analysis is used or the application of dedicated programs, there are disadvantages such as heavy workload, auxiliary work (such as unit division, data compilation, etc.), limitation by calculation means (large or medium-sized computers required) Higher computing costs. These shortcomings are even more conspicuous for preliminary designs that require less computational accuracy.
