The invention belongs to the technical field of aeroelasticity tests, and particularly relates to a flutter wind tunnel test model control surface electromagnetic damping device. Comprising a flutter wind tunnel test model control surface which is installed on a control surface rotating shaft; the metal sheet is fixedly arranged at the root part of the flutter wind tunnel test model control surface; one end of the electromagnet is installed on an electromagnet support, the other end of the electromagnet is close to the metal sheet, an electromagnet coil and a direct-current power source are wound around the electromagnet, the direct-current power source is connected with the electromagnet coil through a cable, and an adjustable resistance load is connected to the cable in series. According to the flutter wind tunnel test model control surface electromagnetic damping device, simulation and parameter adjustment of control surface motion damping can be realized in a flutter wind tunnel test, and physical characteristics of a real aircraft can be simulated more truly; the device can also serve as a protection means of a flutter wind tunnel test model to protect the test model.
