The simplified model for bearing stiffness is built based on relevant theory knowledge about axisymmetric thin circular plate,the concepts and equations for axial and radial deformation parameters are presented.The factors influ-encing deformation parameter are analyzed,such as structural parameters (outer radius,inner radius and thickness)of circular plate with hole and poisson ratio of material.The application process of simplified model for bearing stiffness is discussed,and the relevant conclusions about axial and radial deformation parameters are verified by numerical meth-od.Taking the first order bending mode calculation for a type of water ring vacuum pump rotor as an example,the sim-plified model for bearing mechanics is validated.
