| Abstract: | To implement the strength design for the generator rotor support of direct driven Wind Turbine Generator System (WTGS), the finite element software and the fatigue analysis software is used to study the application of finite element method in the analysis of ultimate strength and fatigue strength. The finite element model of the direct driven generator is established based on HyperMesh and the ultimate strength of the rotor support is calculated by MSC Nastran. When the ultimate strength do not meet the design requirement of the strength, the structure of rotor support is optimized. The fatigue damage is calculated and optimized by fatigue software. Finally, the optimized structure is satisfied with the design requirement of the strength. |
