  • The ball bearing is widely used in aero-engines.Its mechanical properties exert important influence on the dynamic characteristics of rotor systems,especially at high speed.Research on aero-engine high-speed ball bearing has important significance.Considering radial load,axial load,centrifugal force and gyroscopic moment acted on the ball bearing simultaneously,an analysis model based on quasi-dynamic method was set up in this paper.The effects of different structural parameters,such as contact angle,deformation and stiffness and load parameters on bearing mechanical properties were studied.Finally,the method is verified by experiment.
