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.
