摘要：风电机组主机吊具的结构强度关系着吊装作业的安全，需要进行严格校核。以某MW级风电机组的主机吊装为例设计了吊具，采用ANSYS软件，结合实际的吊装过程进行有限元建模，并计算吊具的强度；根据有限元计算结果、应力分布以及变形情况，对风电机组主机吊装过程中吊具的受力情况进行了分析，优化了主机吊具的结构。优化后的风电机组主机吊具最大von Mises应力由733.71 MPa减小到224.86 MPa，应力降低了69.4%，满足强度要求；同时，主机吊具的重量由10685.07 kg减小到9587.46 kg，重量减少了约10.3%，降低了吊具的材料成本。

Abstract：The structural strength of the wind turbine lifting appliance is related to the safety of hoisting operation, and needs to be checked strictly. Taking the hoisting of a MW wind turbine as an example, the lifting appliance is designed. ANSYS software is used to carry out finite element modeling combined with the actual hoisting process, and the strength of the lifting appliance is calculated. According to the results of finite element calculation, stress distribution and deformation, the force condition of the lifting appliance in the hoisting process of wind turbine is analyzed, and the structure of the lifting appliance is optimized. After optimization, the maximum von Mises stress of the wind turbine lifting appliance is reduced from 733.71 MPa to 224.86 MPa, and the stress is reduced by 69.4%, meeting the strength requirements. The weight of the lifting appliance is reduced from 10685.07 kg to 9587.46 kg at the same time, and the weight is reduced by 10.3% and reduces the material cost of the lifting appliance.
