| Abstract: | In combination with the structural features of high-speed electric spindles,the paper explained the basic laws and general characteristics of the dynamics of their ball bearing-rotor systems which receive support from ball bearings.Following the analysis of the kinetic supporting stitfness of angular contact ball bearings rotating at high speed,it established the analysis model and discovered numerical calculation method for the ball bearing-rotor systems′ dynamics using the finite element method.Furthermore,it analyzed the impact of the parameters in the areas of the ball bearings′ internal structures and external working conditions on the dynamics of the rotor system. |
