The invention aims to provide a wind vibration vortex amplification frequency testing device. The wind vibration vortex amplification frequency testing device comprises a wind vibration testing pipeline, a motor, a fan and a test piece fixing base, wherein the front end of the wind vibration testing pipeline is a cuboid; the tail end of the wind vibration testing pipeline is a barrel; the cuboid and the cylinder are in smooth transition; the end part of the cuboid is provided with an opening; the end face of the barrel is provided with an adjustable shutter; the motor is arranged on the back side of the barrel; the fan is arranged inside the barrel; the motor and the fan are connected with each other through a transmission shaft; the bottom of the cuboid is provided with a sliding door; the test piece fixing base is arranged below the cuboid, and is positioned on the sliding door; a straight bar is fixed on the test piece fixing base; a revolving shaft is arranged at the top end of the straight bar through a key slot; the revolving shaft is connected with a test piece fixing plate for fixing a test piece; a pressure gauge and an acceleration meter are arranged on the test piece fixing plate; the inner wall of the cuboid is provided with a wind speed measuring instrument. By adopting the wind vibration vortex amplification frequency testing device, the wind-induced vibration situation under a practical condition can be effectively simulated, and the measurement of vortex amplification frequency can be realized to the maximum extent.
