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.
