| 摘 要： | 针对实验室高速精密磨床用陶瓷轴承电主轴,在有限元分析软件中建立了三维有限元模型,对主轴部件进行了模态分析,得出了主轴前五阶固有频率和振型,对刚性支承和弹性支承情况下主轴模态进行了对比分析,为下一步进行详细的陶瓷轴承电主轴动力学分析打下基础。

| Abstract: | This paper takes the high-speed ceramic bearing electric spindle used in laboratory for example,establishes the 3D FE modle of the spindle and calculates the result of vibration modle analysis of it in the ANSYS. The first five natural frequency and vibration modles of the spindle are obtained and we analysis the result with rigidity support compared with elasticity support.They lay a solid foundation for the dynamic characteristic analysis of the ceramic bearing electric spindle in the next. |
