The invention discloses a power antiresonance vibration absorption device. The power antiresonance vibration absorption device comprises a first connecting structure, a second connecting structure, abuffer structure and a mass block, wherein the first connecting structure is used for fixing a flight controller; the second connecting structure is used for connecting a helicopter main body which generates vibration load during flight; the first connecting structure can only move along a vertical direction relative to the second connecting structure; the buffer structure is elastically connectedwith the first connecting structure and the second connecting structure along the vertical direction; and the mass block is elastically suspended on the first connecting structure, and can generate vibration in the vertical direction relative to the first connecting structure. The flight controller only has one degree of freedom along the vertical direction. Meanwhile, the vibration energy of theflight controller is transferred onto the mass block by means of the power antiresonance principle, thereby reducing the vibration load transferred to the flight controller by the helicopter during the flight, and further improving the control accuracy of the flight controller. The invention also discloses an unmanned helicopter provided with the power antiresonance vibration absorption device.
本发明公开了一种动力反共振吸振装置,包括第一连接结构,用于固定飞行控制器;第二连接结构,用于连接在飞行中产生振动载荷的直升机主体,第一连接结构相对第二连接结构仅可沿竖直方向运动;沿竖直方向弹性连接第一连接结构和第二连接结构的缓冲结构;弹性悬挂在第一连接结构上的质量块,质量块能够相对第一连接结构产生竖直方向的振动。本发明使飞行控制器仅具有沿竖直方向的一个自由度;同时利用动力反共振原理,将飞行控制器的振动能量,转移到质量块,从而降低直升机在飞行中传递至飞行控制器的振动载荷,进而提高了飞行控制器的控制精度。本发明还公开了一种具有上述动力反共振吸振装置的无人直升机。
