| Abstract: | In order to study the angular contact ball bearing of the test table's spindle-beating system,a pre- cision mathematical model of stiffness matrix was established by using the theory of geometry and kinematics of rolling element bearing and hertzian contact stress,and a comprehensive bearing stiffness matrix was pro- posed.The numerical arithmetic to estimate the deflections corresponding to the loads applied to the bearing is also discussed.The calculating software used to solve the stiffness matrix of beating was developed from the theoretical model.The study provides bases for boundary condition processing through finite element analysis of the spindle-bearing system. |
