机床基础件动态特性的有限元分析

Finite Element Study of Dynamic Characteristics of Main Components of Machine Tools

本文用有限元法研究了机床基础件的动态特性.编制了多单元动静结构分析程序,使得能够分析各种基础件和各种计算模型.提取矩阵特征对的方法采用迁移子空间迭代法,它具有效率高和精度高的优点.本程序也能在国产TQ—16计算机上求解其它类型复杂结构任意所要求的特征对.

Dynamic characteristics have been studied for main components of machine tools by finite element method. The multi-element static and dynamic structural analysis program makes possible the analysis of main components in various computing models.The eigen pairs are solved by the transfer sub-space iterative method with the advanta ges of high efficiency and precision. The program can be executed on the China-made corn puter TQ-16 and arbitrary sets of eigen pairs for the treatment of dynamic characteristics of complex structures of various kinds are thus obtained.
