Cabin cover optimization analysis method and system considering rigidity

The invention belongs to the technical field of wind power generation, and provides a rigidity-considered cabin cover optimization analysis method and system.The method comprises the steps that firstly, according to the size condition, features which do not affect an analysis result in a geometric model are determined to be subjected to compensation and deletion processing, and the processed geometric model is obtained; secondly, determining a dangerous area of the geometric model during grid division, and performing cutting grouping and grid refinement on the dangerous area; by making up, deleting and combining the features which do not influence the analysis result, the model is simplified, the calculation amount is reduced, meanwhile, cutting grouping and mesh refinement are carried out on the dangerous area, general mesh division is carried out on other areas, on the basis of ensuring the analysis result of the dangerous area, the mesh number is reduced, the calculation amount is further reduced, and the
