| Abstract: | For analyzing and enhancing dynamics performance of high-speed spindle of NC winding machine, based on finite element method, using ANSYS, the dynamics performance of the high-speed spindle of SKR-4DQ NC winding machine was analyzed, while taking support stiffness and spindle parts into account. The first three vibration modes and inherent frequency of the spindle with different support stiffness were concluded ; The influences of different support stiffness for inherent frequency of the spindle were analyzed. The experimental result indicates that the spindle of SKR-4DQ CNC winding machine can work under 15 000 r/min as rigidity rotor. |
| Keywords: | high-speed spindle dynamic analysis support stiffness finite element |
