The invention belongs to the technical field of helicopter fatigue tests, and discloses an anti-torsion bar rocker fatigue test device and test method. The device comprises a dowel bar, a sliding pair mechanism, an axial anti-torsion load transmission mechanism, a double load transmission mechanism, a torque loading mechanism, an anti-torsion bar, a rocker, a constraint connecting rod and a rack. An axial load F is vertically loaded to the axial anti-twist load transmission mechanism by the dowel bar through the sliding pair mechanism and then is transmitted to the double-load transmission mechanism; the torque M is transmitted to the double-load transmission mechanism through the torque loading mechanism; the double-load-transfer mechanism is connected with one end of the rocker, the other end of the rocker is connected with one end of the constraint connecting rod, and the other end of the constraint connecting rod is fixed to the rack. And the other end of the anti-torsion bar is fixed on the rack.
