Abstract:
In order to verify the feasibility of active vibration control of the rotor hub based on rotating force generator,a prototype of rotating force generator is designed and the output and control characteristics of the rotating force generator are verified by performance test. Then a set of active vibration control test system for the rotor hub is developed,and the active vibration control test of the rotor hub based on the rotating force generator is carried out under global frequency feedback adaptive vibration control algorithm. The test results show that the active vibration control system developed can well suppress the vibration load in the hub plane,and the vibration level of target frequency of the rotating coordinate system can be dropped by 85%. Meanwhile,it has goodtracking and adaptive ability for the change of vibration amplitude and phase.
