Gear-bearing coupling dynamics characteristics of wind turbine planetary gear transmission system under variable load
摘要
Abstract
Considering that the transmission system of wind turbine works in complex and changing load environment caused by stochastic wind speed,this paper uses sparse least squares support vector machine(SL-SVM) to simulate wind speed of true wind field,and obtains time-varying wind load caused by stochastic wind speed.The lumped-parameter method is used to develop a dynamic model of planetary gear transmission system of wind turbine coupled with bearing.The model includes the varying wind load,time-vary mesh stiffness of gear pair and time-vary stiffness of rolling element bearing.The numerical method is used to simulate the dynamic performance of planetary gear system of Multibrid Technology Wind Turbine with 1.5 MW rated power.The vibration displacement responses of the transmission system are obtained as well as dynamic meshing force each pair of gear and nonlinear bearing forces.The research can provide a foundation for optimizing dynamic performance and reliable design of gear transmission system of wind generator.关键词
