Dynamic analysis of back body of TH65100 horizontal machining center based on finite element

The main content of this paper is dynamic analysis and the improved structure of back body of TH65100 horizontal machining center. The boundary conditions are established and the structure of back body is studied by finite element modal analysis. The results indicate back body has the disfigurement that torsional rigidity is not enough. The improved scheme is presented which aim at the disfigurement of structure of back body and the improved structure is testified. The main disfigurement of structure of back body is improved is this scheme which enhance the economical efficiency of the manufacture of back body.
