Dynamic Modeling and Multi-Condition Simulation Analysis of Wind Turbine Bearing
摘要
Abstract
The service environment of wind turbine bearing is complex and harsh.It is very important to es-tablish the dynamic model of wind turbine bearing and conduct multi-condition simulation to optimize the bearing structure.The traditional dynamic model of wind turbine bearing regards the parts as rigid bodies,and does not consider the flexible deformation of the inner ring and cage of the main bearing,resulting in relatively low simulation accuracy.A rigid-flexible coupling multi-body dynamic model of wind bearing is established for the inner ring and cage flexibility of the main shaft bearing of megawatt wind turbine,and the accuracy and reliability of the model are verified.The established dynamic model is subjected to multi-condition simulation,and the results show that the rotor speed from starting to run smoothly,as well as sudden changes in speed,would cause significant impact of the rollers and the inner ring and cage.Mean-while,the change in contact force between the rollers and the inner ring under sudden speed change is con-sistent with the change in contact force between the rollers and cage.It has a certain reference value to op-timize the structure of wind turbine bearing and improve the service life of wind turbine bearing.关键词
