bearing, the research results and methods pertaining to spherical plain bearings can be used for reference. XIANG et al [13] optimized the structure of GEZ101ES for a radial spherical plain bearing using a finite-element model. By keeping the assembly dimension unchanged, they obtained the optimal value of the ball diameter under static loading through a numerical experiment. LU et al [14] analyzed......
