| 摘 要： | 本文对机床结构中典型的结合面——螺栓结合面进行了研究,用有限元法建立了结合部的动力学模型,对结合面动态参数的识别方法进行了理论分析和推导,在此基础上,编制了求解接触刚度和接触阻尼的计算机程序ISD1,通过程序与实验相结合的方法,识别出了结合面本身的接触刚度和接触阻尼,为整台机床的动态特性分析和动态优化设计奠定了基础。

| Abstract: | This paper studies a typical joint in machine tools, the bolt joint, and introduces the dynamic model of the joint established by using the finite element method. Then on the basis of the method for identifying the dynamic parameters of the joint, this paper works out a computer program ISDI for calculating the contact stiffness and the contact damping of the joint. The results show that by using this program together with experimentation, the contact stiffness and the contact damping of mechanic joints can be identified satisfactorily. This approach may foim the basis of the dynamic analysis and the dynamic optimal design of machine tools. |
