Dynamic Response Characteristics of Wind Turbine Generator System Transmission Chain and Influence of Support System
In this paper,a wind turbine generator system is taken as the basic research object to study and analyze the multi-body dynamics simulation model of rigid-flexible coupling of transmission chain.The research results show that the support system has extremely great influence on the modality of vibration energy usually distributed in the gears and boxes of the generator housing,and the scientific and reasonable height design of the support system is conducive to reducing the probability of sympathetic vibration risk of the transmission chain.The deviation of component vibration velocity caused by resonance is very large,and increasing the elastic support height of the gearbox while reducing the elastic support height of the generator can reduce the vibration level of the transmission chain.
