Selection Analysis Research Of Vibration Point About The Wind Motor Gearbox Fault Diagnosis

The outstanding problems in Wind turbine gear fault diagnosis and condition monitoring technology: failure wind turbine site stringent test conditions (temperature, noise, electromagnetic interference, height), gear type (gear) wind turbine vibration difficult test, accuracy is poor, severely restricted the wind turbine mechanical fault diagnosis technology in-depth and extensive research, but also affect the wind turbine condition monitoring technology and applications.In this paper, 750KW wind turbine gear box as the research object, wind power gear box system on the causes of vibration of the foundation of theoretical analysis and the establishment of transmission of the vibration parameters of its equation, the use of MATLAB simulation software, a preliminary understanding of wind power gear box drive system vibration characteristics, the other three-dimensional drawings using UG software built 750KW wind turbine gear box of three-dimensional solid model, and dynamic simulation software ADAMS established its simulation model, in which three-dimensional model based on the gear box the integrated use of dynamic simulation software, Adams, carried out on the gear kinematic analysis and vibration analysis, were drawn out of the wind turbine gear box of the main gear and shaft speed curves, and various gears in the transmission process suffered The curves of meshing force and analyzed, and the use of vibration analysis module ADAMS gearbox condition monitoring of commonly used vibration measuring point a preliminary analysis of the preliminary draw of the main components of the gearbox vibration characteristics for the wind turbine site fault monitoring and diagnostic test for selecting measurement points when some direct references.
