Problems solved by technology

[0004] The optimization method of shell element model is generally used to optimize the plate thickness of structural parts, the optimization variable is single, and the optimization range is limited; and the application range of shell elements is limited, which is only applicable to a small number of structural parts
[0005] The optimization method of the volume element model establishes shape variables through the mesh deformation tool. After the mesh is deformed, the quality of the mesh is likely to be poor, so the optimization range is limited, and the poor quality of the mesh is easy to cause calculation non-convergence
