Abstract

The present invention relates to the technical field of helicopter main support beam tests, especially to a main support beam fatigue test device. The device comprises a main support beam (15), connection support seats and a load module. There are four connection support seats arranged on the main support beam (15); the load module comprises an X-directional load loading joint (11), a Z-directional load connection fork ear (12), a Y-directional balance load loading joint (13) and a Y-directional load loading joint (14), wherein the X-directional load loading joint (11), the Z-directional loadconnection fork ear (12) and the Y-directional load loading joint (14) are configured to apply loads in X, Y and Z directions to a main support beam fatigue test device, and the Y-directional balanceload loading joint (13) is configured to eliminate the bending moment of a Y-directional load to a connecting bolt. The main support beam fatigue test device is simple in structure and convenient to dismount, can meet boundary simulation when the main support beam fatigue test is performed, and can apply load to the main support beam according to test requirements.

Description

technical field [0001] The invention relates to the technical field of helicopter main reduction support beam tests, in particular to a fatigue test device for main reduction support beams. Background technique [0002] The main reduction support beam is an important load-bearing part of the helicopter. In order to grasp the fatigue life of the main reduction support beam, the fatigue test must be carried out on the main reduction support beam, and the fatigue characteristics of the main reduction support beam are obtained, and then the life of the main reduction support beam is given. The main reducing support beam needs to apply loads in the X, Y, and Z directions to the test piece at the same time during the test. At the same time, when the Y direction is applied, the bending moment of the Y direction load on the connecting bolts must be eliminated. Therefore, a Y direction must be applied in the Y direction. Balance the load towards the bending moment. At present, there...
