| Abstract: |
| In order to describe the performance of thin wall bearing on rotor system more accurate, the simplified model of bearing local stiffness was proposed. The load distribution and local contact deformation in angular contact ball bearings were calculated using quasi dynamic calculation method. Based on the relationship of local load to contact deformation, the calculation model of local bearing stiffness was subsequently built to get radial and axial components of local stiffness. Effects of external loads on the local bearing stiffness were analyzed. The results showed that local stiffness in bearings is symmetric to the axis of radial load, and its value has a maximum on the symmetry axis along the radial load direction. External radial and axial load have different effects on local bearing stiffness. |
