摘要:
利用Pro/E建立了空心主轴单元的三维模型,采用ANSYS对空心主轴单元进行了振动特性分析。通过在空心主轴上选取的6个关键节点,并取前轴承不同位置,对比分析不同前轴承位置时的固有频率及相应6节点处的振动特性,得到如下结论:刀具和调刀套节点处的振动对棒材加工精度影响最大,并在此基础上对空心主轴结构进行优化,提高了加工精度。

Abstract:
The three-dimensional model of the hollow spindle unit is established with Pro/E. And the vibration characteristics of the hollow spindle unit are studied with ANSYS. Six key nodes on the hollow spindle and different positions of the front bearing are selected and the vibration characteristics are comparatively studied. The results show that the rod machining precision is greatly influenced by the vibration of the nodes of knives and knife pouches. Based on the results, the structure of hollow spindle is optimized and the machining accuracy is improved.
Key words:    centerless lathe    hollow spindle unit    ANSYS    vibration characteristic analysis    structure optimization
