Spindle Static and Dynamic Characteristics Analysis of Precision CNC Turning Center

摘要

In this paper,a research of precision CNC turning center's spindle is presented.Spring damper elements are used to simulate the supports of dynamic and static hydraulic bearing,and the 3D finite element models of the spindle is built.Based on finite element models of spindle,the static analysis and model analysis are performed,and the static stiffness,natural frequency and modes of vibration are put forward.The strain and stress of spindle is explored,and mode of vibration of spindle under resonance and designed working conditions is contrasted.
