The invention provides an unmanned aerial vehicle power system damping device, and relates to the technical field of unmanned aerial vehicles. The vibration reduction device for the power system of the unmanned aerial vehicle is configured between a motor and a motor base of the unmanned aerial vehicle, the vibration reduction device for the power system of the unmanned aerial vehicle comprises at least one first vibration reduction layer and at least one second vibration reduction layer, the hardness of the first vibration reduction layer is larger than that of the second vibration reduction layer, and the first vibration reduction layers and the second vibration reduction layers are alternately stacked. According to the vibration reduction device for the power system of the unmanned aerial vehicle, through the multi-layer soft and hard stacked structure, namely, the first hard vibration reduction layers and the second soft vibration reduction layers are alternately stacked, an energy dissipation system with structural damping as the main part and material damping as the auxiliary part is generated, the structure is simple, reliability is high, wide applicability is achieved, and the vibration reduction device is installed between a motor and a motor base of the unmanned aerial vehicle and has good vibration reduction performance. The vibration level transmitted to a fuselage by a power system of the unmanned aerial vehicle can be reduced by 20%-50%, the service life of the unmanned aerial vehicle is prolonged by about 15%-30%, and the unmanned aerial vehicle is suitable for the unmanned aerial vehicle with the take-off weight within 100 kg.
