In order to solve the problem that the servo accelerometer-based inclinometer is always affected by vibration of the aerodynamic test model when measuring the angle of attack in the intermittent transonic wind tunnel, a vibration effect correction method based on two tri-axial accelerometers is proposed in this paper. In this method, the tri-axial accelerometers are symmetrically mounted on the front and rear sides of the inclinometer along the sensitive axis, and then the centrifugal accelerations caused by different vibration modes and different directions are calculated by time-frequency analysis, numerical integration and equivalent formula. Finally, the total angle measurement error can be accumulated by the angle measurement error caused by each vibration mode. Experimental results of intermittent transonic wind tunnel show that the difference between the proposed method and the Elastic Angle Correction method is less than 0.05 degree when the vibration peak is less than 5 g.
