| description | The invention provides a wind generating set main shaft analysis method and system and an analysis terminal, and relates to the field of wind generating sets. Configuring a three-dimensional state diagram of the whole main shaft; assembling other parts by taking the three-dimensional state diagram of the main shaft as a reference to obtain a finite element model required by main shaft analysis; layered segmentation is carried out on the surface of the main shaft, two layers of common-node thin film units with different unit sizes are arranged, and mesh generation is carried out on the common-node thin film units through hexahedron eight-node units; performing static strength stress analysis on the main shaft of the wind turbine generator to determine the limit safety margin of the main shaft; and performing fatigue strength analysis on the wind turbine generator main shaft to determine reasons and areas where fatigue damage possibly occurs on the main shaft, and completing stress analysis of the wind turbine |
