摘要
针对龙门机床横梁导轨副结合面参数识别的问题,提出了基于参考相关结合面参数经验值,采用实验模态分析与有限元分析相结合的方法,对滚动直线导轨副结合面参数进行识别,在此基础上对横梁的动态特性进行分析。计算结果与实验结果的比较表明,采用的结合面参数识别方法是有效的。
The contact parameter identification for gantry machine tool beams guideway is a conventional research topic. This paper adopt a method for the contact parameter identification of linear rolling guide based on the relevant experience values. Modal experiment analysis is combined with finite element analysis. On this ground, the dynamic characteristics analysis of the beam is made. The comparison of finite element analysis results and the experimental results confirms the validity of this research methods.
