The invention relates to the field of wind tunnel tests of large wind turbine blades and aviation wings, in particular to a two-degree-of-freedom aeroelasticity experimental device which comprises a wind tunnel experimental model, a two-degree-of-freedom supporting mechanism and a signal acquisition system. The wind tunnel experiment model comprises a wing section model, a piezometric tube, an end plate, a center torsion shaft, a locking mechanism and a mass center adjusting mechanism. The two-degree-of-freedom supporting mechanism comprises a wind tunnel fixing plate, a wind tunnel anti-turbulence cover, a supporting plate, a linear bracket, an angular displacement sensor fixing flange, a torsion shaft fixing rod, a torsion supporting rod, a smooth linear straight rod, a sinking and floating elastic mechanism, a pitching linear spring, a pitching spring connecting column, a linear sliding bearing, an outer spherical bearing, a sinking and floating limiting device and a pitching limiting device. The device can be used for researching aeroelasticity characteristics of a wind tunnel experiment model under pitching and sinking-floating two-degree-of-freedom supporting conditions, that is, the device is an experiment device for exploring phenomena such as wing section surface flow separation, dynamic stall and flutter during aeroelasticity tests.
