Abstract
The invention belongs to fatigue test techniques for flexible beams of bearingless rotor wings and relates to a centrifugal force loading device for a flexible beam of a bearingless rotor wing. The centrifugal force loading device is characterized by comprising a centrifugal force outer frame, a thrust ball bearing, an antifriction bearing, a cover plate, a flexible beam connector and a locknut; the centrifugal force outer frame is in a frame structure, and one lateral side of the centrifugal force outer frame is provided with a bearing mounting hole; one end of the flexible beam connector is provided with a stepped rotating shaft; the cover plate is in a circular boss structure, and the middle of the cover plate is provided with a through hole; the antifriction bearing is mounted on a bearing mounting hole of the centrifugal force outer frame; the boss of the cover plate presses the outer periphery of the antifriction bearing; the flexible beam connector penetrates the antifriction bearing to be connected onto the centrifugal force outer frame through the thrust ball bearing; a test load is applied through an execution mechanism. The centrifugal force loading device for the flexible beam of the bearingless rotor wing has the advantages that torque loading is unaffected when a centrifugal force is applied, and the purpose of testing the fatigue performance of the flexible beam of the bearingless rotor wing can be fulfilled.
