Abstract:This article established a three-dimensional finite element model of one certain machining center spindle, by using the spring damper element simulation method of dynamic and static pressure bearing. The research made a static analysis and modal analysis, and got the static stiffness, natural frequency and vibration mode respectively at the same time. The main stress and strain analysis has been done. and the spindle in the resonance and the desigm condition of the mode also has been compared. In one word, the research could provide the basis for improving the design of spindle structure.
Keywords:precision turning center  spindle  static analysis  dynamic analysis
