Shifting fork and shifting fork structure checking method and device

The invention discloses a shifting fork and a shifting fork structure checking method and device.According to the checking method, in a finite element analysis environment, the axial assembling gap between the shifting fork and a gear sleeve is obtained, and the side contact face of the shifting fork is configured to be a convex curved face, so that the shifting fork can be subjected to simulation application in the finite element analysis environment; the target position is determined on the convex curved surface according to the axial assembly clearance, it is guaranteed that the shifting fork can be accurately converged during finite element analysis, loads are loaded on the preset loading point of the shifting fork to obtain loading deformation of the target position on the shifting fork, and the structure checking result of the shifting fork is determined according to the loading deformation. The whole checking process is simulated and checked in a finite element analysis environment, the trial-manufactu
