In this paper, the research object is the XM18 spherical generator, in order to improve the dynamic behavior of the machine tool, the following aspects have been studied in this thesis: Firstly, based on the elasticity theory and finite element analysis theory, the finite element models of the lathe bed, dovetail, dovetail shelf, headstock, fanlike plank and millhead shelf, which were the main parts of the spherical generator, were built up using ANSYS9.0. And based on the modal analysis theory and FEM technology, the free modal and the constrained modal analysis of the main parts were studied. Accordance to the analytical results, put forword methods to optimize the key parts.
