Research on Dynamic Characteristics Analysis of the Whole Grinding Machine Tool Based on FEM

Abstract:

Dynamic characteristics is the foundation of the dynamic design of the machine tool, while the key factor of establishing the accurate dynamic model of the machine tool is the treatment of the joint surface. In this paper, the whole machine tool model is built with the software PRO/ E, and the software MSC. Patran is used to mesh the finite element of super-high-speed grinder and set up the boundary conditions. Then Yoshimura method is used to determine the junction parameters and establish the dynamic model of the junction. The software MSC. Nastran is used to analyze the modal of the whole machine. At last, on basis of identifying the weaknesses of the structure of the machine tool, the paper provides a theoretical basis for the improvement of the machine tool design.
