The invention relates to an atmospheric turbulence simulation device, and belongs to the field of wind tunnel tests. Comprising blades, a rotating shaft, an upper angular contact ball bearing, a lower angular contact ball bearing, a force bearing base and a driving motor, the force bearing base is of a hollow structure in the axial direction, the rotating shaft penetrates through an inner cavity of the force bearing base, an output shaft of the driving motor is connected with the lower end of the rotating shaft, and the upper end of the rotating shaft is fixedly connected with the blades; an upper angular contact ball bearing and a lower angular contact ball bearing are sleeved at the upper end and the lower end of the middle equal straight section of the rotating shaft respectively, the lower end face of an outer ring of the lower angular contact ball bearing is in close contact with a step of an inner cavity of the force bearing base, and the upper end face of an outer ring of the upper angular contact ball bearing is in close fixed connection with the upper end face of the force bearing base through a flange. According to the device, the number of intermediate transmission links is small, the transmission error is reduced, the control precision is improved, the blade can be continuously and stably controlled, and reliable test equipment is provided for a wind tunnel test.
