Design Optimization for the Reinforcement of Wind Turbine Foundation

  Introduction  With wind power entering the era of parity, the design optimization of fan foundation reinforcement is of great significance.

  Method  In a practical engineering case, the CFD foundation design software was used for structural design. Then, the finite element model of wind turbine foundation was established by ABAQUS software.

  Result  The analysis shows that, the position of the inner end of the radial reinforcement and the inner ring of the circumferential reinforcement are the positions of the maximum stress in the reinforcement system. Through analysis, the problems existing in the reinforcement calculation of traditional design method are found. Reinforcement optimization is summarized and compared with the original reinforcement scheme.

  Conclusion  The optimization range of radial reinforcement and circumferential reinforcement is more than 10%. These conclusions can be used to guide engineers for design optimization.
