Abstract

Motorized spindle is product of mechatronics. Its dynamic performance considered and predicted is the precondition for the optimization design of machine tool spindle system. Based on the coupling relationship among magnetic field，electric field，temperature field and structure field of motorized spindle, this paper establishes finite element model coupled multi-physics for 150MD24Z7.5 motorized spindle. By calculating electromagnetic loss and bearing friction heat, the temperature field and structure of motorized spindle is simulated, and the coupling relationship between thermal characteristics and vibration characteristics of motorized spindle is discussed. The effect of air-gap on the vibration characteristics by thermal deformation is analyzed and verified by experiment. The results show that thermal deformation influences greater on vibration amplitude, electromagnetic force amplitude increases by 12.1% caused by the change of air-gap. With the model coupled multi-physics can predict the vibration amplitude for motorized spindle and the prediction error is 10.2%.
