The invention discloses a control device for translational oscillation test for automatic change of the attack angle of a model so as to overcome the defects of low efficiency and poor attack angle positioning accuracy of the translational oscillation test and greatly improve the efficiency of the translational oscillation test of a low-speed wind tunnel and the accuracy of dynamic derivative testdata. The device comprises an upper computer control unit, a network communication unit, a touch screen control unit, a PLC signal module unit, a 32 KW servo drive control unit, a main motor drive unit, a sine generator unit, a linear displacement feedback unit, two sets of 1 KW servo drive control units, a heave variable-angle electric cylinder unit and a sidesway variable-angle motor unit. Themain motor drive unit and the sine generator unit form a translation oscillation driving mechanism; and the heave variable-angle electric cylinder unit is responsible for automatic change of a model attack angle in a heave oscillation mode, and the sidesway variable-angle motor unit is responsible for automatic change of the model attack angle in a sidesway oscillation mode. The touch screen control unit controls the closed-loop motion of the main motor drive unit, the heave variable-angle electric cylinder unit and the sidesway variable-angle motor unit.
