Abstract

The natural frequency is a dynamic characteristic which has an importance role for the performance, accuracy and stable of a spindle as well as machine tools. In this study, modal analysis for the spindle including shaft, housing and bearing parts have been established to predict the natural frequency and mode shape by using ANSYS software. The housing that was often neglected in previous researches is included in present finite element model to improve the analyzed results. The support bearings are replaced by springs with equivalent stiffness during analysis process. The natural frequency and mode shape for different preloads are obtained. The critical speed is estimated. The results herein will provide information for engineer during developing a new design of spindle match costumer’s requirement.
