Dynamic Analysis of the High-Speed Spindle Structure for Machining Center
초록
this paper presents a dynamic analysis of the high-speed spindle system for vertical machining center using finite element techniques. The computed natural frequencies are compared with the measured frequencies obtained from experimental modal analysis. The results show that the bending and twisting deformations of the spindle housign dominated in the lowest modes owing to low dynmic stiffness of the housing structure. The design parameters used in the analysis are:(a) panel thickness of the housing (b) height of the housing and (c) spindle-to-column distance of the housing. Through sensitivity analysis and optimizing simulation considering design constraints an optimal design of the spindle system has been obtained.
