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.

    本发明属于直升机疲劳试验技术领域,公开了一种防扭杆摇杆疲劳试验装置及试验方法。装置包括:传力杆、滑动副机构、轴向防扭传载机构、双传载机构、扭矩加载机构、防扭杆、摇杆、约束连杆、台架;轴向载荷F由传力杆通过滑动副机构垂直加载至轴向防扭传载机构,再传递至双传载机构;扭矩M通过扭矩加载机构传递至双传载机构;双传载机构与摇杆一端连接,摇杆另一端连接约束连杆的一端,约束连杆的另一端固定至台架上;防扭杆一端与摇杆中部连接,另一端固定至台架上。
