Static and Modal Characteristic Analysis of a Horizontal Machining Center

Article Preview

Abstract:

In order to get an accurate analysis results for static and modal characteristics of a machining center, finite element analysis method was taken. Taking a horizontal machining center as example, solid model was established firstly. Finite element model containing joint parameters was established in ANSYS. With the help of finite element method, static and modal characteristics of the horizontal machining center were carried out. It was concluded that the horizontal machining center has comparatively smaller static stiffness in Z direction; in order to improve modal characteristic of the horizontal machining center, the column and worktable should be paid more attention. The research results provide guidance for finite element analysis and optimization of whole machine tool.
