The invention discloses a wing-shaped oscillation mechanism with a variable initial attack angle for an icing wind tunnel and a working method, belongs to the technical field of icing wind tunnel construction, and aims to solve the problem that the amplitude and the average attack angle of an existing wing-shaped oscillation mechanism for the icing wind tunnel cannot be adjusted in a stepless manner. Comprising a worm, a turntable bearing, a rotary drum, a rotary direct-drive motor and a model rotating shaft, the rotating drum is rotatably arranged on the side wall of the test section, the model rotating shaft is rotatably arranged on the rotating drum, the rotating drum is connected with an outer ring of the turntable bearing, an inner ring of the turntable bearing is connected with the side wall of the test section, worm gear teeth are arranged on the periphery of the turntable bearing, an output shaft of the servo motor is connected with one end of the worm through the speed reducer, and the worm is meshed with the worm gear teeth. One end of the model rotating shaft is connected with the output end of the rotary direct-drive motor, the rotary direct-drive motor is arranged on the motor mounting seat, the motor mounting seat is connected with the rotating cylinder, automatic stepless adjustment of the initial oscillation attack angle of the airfoil profile is achieved, and the frequency and amplitude needed by airfoil profile oscillation are achieved by controlling the rotary direct-drive motor.
