摘要：
In order to quantitatively analyze the influence of the randomness of the structure and material parameters of the high-speed motorized spindle system on the machining quality of the motorized spindle，a system model of motorized spindle，bearing and tool is established based on finite element method. The model considers the influence of mass eccentricity on the vibration characteristics of motorized spindle. In addition，the reliability analysis method of machining accuracy of electric spindle system is proposed by taking allowable tool tip vibration as threshold and combining with Kriging theory. Finally，the coupling effect of spindle speed and preload on tool vibration is analyzed by using the proposed method. The results show that the vibration reliability of tool tip caused by unbalance increases with the increase of spindle speed and bearing preload respectively. © 2024 Editorial Board of Jilin University.
