Based on the sub-dynamics analysis theory and race’ s control theory, this paper introduces the mathematic model of the angular contact bearing rigidity and ratio of revolution and rolling firstly. Then calculates the ball contact angle, gyro moment, ratio of revolution and rolling, and bearing rigidity by programming in Matlab, and the numerical method. Finally analyzes the influence of the preload and rotary speed on the dynamic parameters of high speed angular contact ball bearings.
