Beschreibung
Zusammenfassung:	The invention discloses a propeller blade fatigue test device, which comprises a blade root holding end flange plate and a blade tip load loading device, and is characterized in that the blade root of a propeller is fixed with the blade root holding end flange plate, and the blade tip is fixed with the blade tip load loading device; the paddle tip load loading device comprises a device shell, a central cylinder, a cylinder pull rope, a cross beam and an actuator cylinder connector. According to the device disclosed by the invention, the blade root is fixed on the test bed through the blade root holding end flange plate, and the main loading load of the blade tip part comprises three main components, including centrifugal force in the axial direction of the blade, aerodynamic force in the vertical direction and loading torque under the combined action of two sides, so that the stress condition of the blade can be truly simulated. The testing device is easy to operate, good in safety, high in bearing capacity a
