It is seen that preload affects natural frequency obviously, and the critical rotation speed will go up if gaining preload. 0 1000 2000 3000 4000 5000 6000 50 150 250 350 Axi al pr el oad( N) Na t u r a l Fr equency( Hz) First order Second order Third order Fourth order Fig. 6 Variation of low order natural frequency along with the variation of preload Table2 Variation of low order natural frequency along with the variation of preload (50~400N) order first-order(Hz) second-order(Hz) third-order(Hz) fourth-order(Hz) variation range of frequency 707~863 1492~1836 4103~4528 5404~5748 Conclusions In this paper, the FEM model of motorized spindle is set up to research on its dynamic characteristics, which is effected by the axial preload on the natural frequency, the motorized spindle's natural frequencies and corresponding vibration shapes, centrifugal forces and gyroscopic moments on the motorized spindle shaft.
