Abstract

Abstract: In order to solve the vibration and noise problems of large-scale wind power generator, this paper takes a certain type of direct-drive wind power generator as the research subject. The axial acceleration of the wind power generator stator is tested by acceleration sensor when the generator is running, effective model of the wind power generator stator is established using finite element software. The natural frequency, mode shape and resonance frequency of the wind power generator stator can be obtained by modal analysis and response analysis, and the finite element simulation results and test results are analyzed. The measured results show that the axial acceleration of the wind power generator stator at 6 o'clock position is much greater than the axial acceleration at 9 o'clock position, and the axial acceleration reaches its maximum when the wind power generator rotates at 9.5 r/min. The simulation results show that the resonant frequency of the wind power generator stator is 23 Hz, which is three times the rotational frequency corresponding to the maximum axial acceleration. Under this frequency, the displacement ratio of the wind power generator stator at 6 o'clock position and 9 o'clock position is close to the measured acceleration ratio. The research can provide references for the actual operation, vibration test and simulation of wind turbines.

Key words: wind power generator, stator vibration test, modal analysis, finite element simulation, response analysis
