[0021] The technical solution of the grain size correction method for the life analysis of the wheel structure of the present invention will be further described in conjunction with the accompanying drawings.
[0022] Considering the impact of the grain size on the life of the wheel structure, combined with the fatigue life model, the present invention proposes a grain size correction method for the life analysis of the wheel structure. The process is shown in figure 1 .
[0023] Step (1), standard sample sampling of different parts of the wheel: firstly, the finite element analysis of the wheel is carried out, the material properties and deterministic load of the wheel are input, and the detailed three-dimensional stress and strain analysis of the wheel structure is carried out, and the wheel is obtained Analysis results of strain, stress and displacement of the disc structure. Then, for the dangerous parts of the wheel disc structure that may have fatigue failure, the stand...
