Dynamic modeling of CNC High Precision Surface grinding machine with Horizontal Spindle and Rotary Table MGK7350

摘要

The dynamic model of machine tool structure is the basic of its dynamic analysis and dynamic optimization. The determination of joint interface stiffness and damping of grinding machine structures is one of key problems to dynamic analysis of machine tools. A method to identify interface dynamic parameters of grinding machine structures using measured transfer function data and optimization technique is presented in this paper. Finally, do the whole machine modal analysis with method and finite element method, contrast the experimental and theoretical results, proved this finite element model can stimulate the dynamic performance of the whole machine effectively, it is of practical value of engineering application.
