Application and Effect Verification of Dynamic Vibration Absorber in Helicopter Vibration Reduction
In this paper,a dynamic vibration absorber with variable stiffness and adjustable mass was designed based on the design principle of undamped dynamic vibration absorber and the actual requirements of helicopter indicators.The dynamic characteristics and the vibration reduction effi-ciency of the dynamic vibration absorber were analyzed by finite element model,and the actual in-stallation effect of the dynamic vibration absorber was verified by flight test.The test results showed that it had a good damping effect,which accumulated engineering experience and provided reference for the subsequent development of other types of dynamic vibration absorber.
