摘　　要：新能源发电领域风力发电机组运行质量的好坏及使用寿命的长短,发电机转子滑环起决定性作用,滑环中护环与转轴配合间隙的确定是目前风电机组发电机结构设计与装配技术难点。通过对目前风电行业通用的某型号风力发电永磁发电机转子滑环结构建立分析模型,根据滑环工作条件下对不同配合情况进行有限元仿真分析,通过仿真最终获得最佳的间隙或过盈量,使发电机能满足最佳工作要求,从而找到滑环结构设计的最佳值,为滑环结构设计及同类结构设计提供理论参考。In the field of new energy power generation,the operation quality and service life of wind turbine are good or bad,and the slip ring of generator rotor plays a decisive role;the determination of the matching clearance between the retaining ring and the shaft in the slip ring is the technical difficulty in the structural design and assembly of wind turbine generator at present. Based on the analysis model of the slip ring structure of the rotor of a wind power permanent magnet generator which is widely used in the wind power industry at present, and according to the working conditions of the slip ring, the finite element simulation analysis is carried out for different matching conditions. Through the simulation, the best clearance or interference is finally obtained, so that the generator can meet the best working requirements, so as to find the best value of the slip ring structure design, which is used to guide the slip ring Structure design and similar structure design provide theoretical reference.
