Application of Dynamic Vibration Absorber in Vibration Suppression of Rotor-blade System
In order to suppress the lateral vibration of the rotor-blade system at the first critical speed,a Dynamic Vibration Absorber(DVA)is designed.The structure of DVA is introduced in this article,then the dynamic model and equations of the rotor-blade-DVA coupling system are established.On this basis,the damping effect of the DVA device is analyzed numerically.Under given parameters,the results show that DVA can suppress the first-order resonance of the rotor and blade in the rotor-blade system respectively,and the effect is better.
