Simulation Analysis on Crack Fault of Planetary Wheel of Wind Turbine Gearbox
摘要
Abstract
Affected by strong alternating load,the gearbox of non-direct-driven wind turbine is easy to break down,therefore,this paper aims to study a new method for diagnosis on crack fault of wheel gear of the wind turbine.It theoretically analyzes characteristics of crack fault vibration signals and establishes a simulation and research model for crack fault of the planetary wheel so as to simulate crack fault of the wheel gear by changing meshing stiffness parameters.Research results in-dicate that when there is crack fault in the planetary gear,meshing of the faulted gear will have peak regulating effect on vibration of the wheel gear.In addition,vibration signals have the characteristic that rotating frequency of the planetary wheel,faulted characteristic frequency and combined regulating sideband are all occurred at both sides of meshing frequency and harmonic of mesh frequency.关键词
