The loading bearing of a variable angle radial loading device was used as the object, the Unigraphics was used for modeling, and then ANSYS Workbench software was used for simulation analysis. Through the simulation, the actual working conditions of the aeroengine shoulder bearing with complex and changeable loads were simulated. At the same time, a plurality of radial loads in different directions were applied to the bearing, and the distributions of stress and deformation of the bearing were obtained. The results show that the maximum deformation and stress values of the bearing increase with the increase of the radial loading angle, and the regional distribution of the deformation also changes with the angle, which will cause poor fatigue life and failure modes of the bearing. The results of the simulation analysis provide a reference for the testing and design of the aeroengine shoulder bearing.
