The invention discloses a method and device for measuring the influence of an additive on flow-induced vibration of a rotor experiment device and application, and belongs to the technical field of vibration and noise reduction. The method comprises the following steps: arranging an acceleration sensor on the surface of an outer cylinder of a rotor experiment device; a liquid outlet in the outer barrel is closed, and a liquid injection opening and a gas injection opening are opened; working liquid is injected into the device through a liquid pipe, and gas in the rotor experiment device is discharged through a gas pipe until the whole device is completely filled with the working liquid; starting a driving piece, and controlling an inner cylinder of the rotor experiment device to rotate around a shaft; when the rotating speed of the inner cylinder reaches a set value, the driving piece is closed, and the inner cylinder continuously rotates around the shaft through inertia; flow-induced vibration signals generate
