The invention discloses a vibration reduction assembly, an unmanned aerial vehicle and an unmanned aerial vehicle vibration reduction method. The vibration reduction assembly comprises a sensor, a processor, an execution actuator and a mass damping stiffness device. The sensor is mounted at a vibration part of the unmanned aerial vehicle and is used for detecting vibration of the unmanned aerial vehicle and outputting a vibration signal; the processor is electrically connected with the sensor and is used for processing the vibration signal and outputting a control signal; the execution actuator is electrically connected with the processor and is used for executing actions according to the control signals; the mass damping stiffness device is installed on the unmanned aerial vehicle and connected with the execution actuator, and the action executed by the execution actuator acts on the mass damping stiffness device, so that the mass damping stiffness device generates displacement opposite to the vibration direction of the unmanned aerial vehicle, and vibration of the unmanned aerial vehicle is weakened. Vibration of any type of vibration of any unmanned aerial vehicle can be reduced, the stress level of key structural parts of the unmanned aerial vehicle can be reduced, and the failure risk of the unmanned aerial vehicle is reduced.

    一种减振组件、无人机及无人机减振方法,该减振组件包括传感器、处理器、执行作动器和质量阻尼刚度器;传感器安装在无人机的振动部位,用于检测无人机的振动,并输出振动信号;处理器与传感器电连接,用于对振动信号进行处理,并输出控制信号;执行作动器与处理器电连接,用于根据控制信号执行动作;质量阻尼刚度器安装至无人机,并与执行作动器连接,执行作动器执行的动作作用在质量阻尼刚度器上,使得质量阻尼刚度器产生与无人机的振动方向反向的位移,以减弱无人机的振动。对于任意无人机的任意类型的振动,均可进行减振,可减小无人机的关键结构件的应力水平,降低无人机失效风险。
