摘　　要：为验证基于旋转力发生器的旋翼桨毂振动主动控制的可行性,设计了一套旋转力发生器原理样机,通过性能测试验证了旋转力发生器的出力及控制特性。开发了一套旋翼桨毂振动主动控制试验系统,采用全局频域反馈自适应振动控制算法,开展了基于旋转力发生器的旋翼桨毂振动主动控制试验,试验结果表明:所开发的振动主动控制系统能够很好地抑制桨毂平面内的振动载荷,使旋转系下目标频率的振动水平下降了85%,且对于振动幅值和相位的变化具有良好的跟踪和自适应能力。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 good tracking and adaptive ability for the change of vibration amplitude and phase.
