The modeling and optimization of machine tool’s dynamic performance remains to be a grand challenge in machine tool design. In this paper. In order to identifying the concentrated modals of a horizontal machining center, a combined experiment modal analysis method is proposed. A FEA dynamic model accurate in frequency and mode shape is built and verified by comparing with EMA results. Based on the model the optimization of frame structure is made, Simulation results shows the optimized frame enhances the dynamic performance of machine tool.
