Railway wagon joint connector strength test loading device and test method thereof

The invention discloses a loading device for a strength test of a joint connector of a railway wagon and a test method thereof, and the device achieves the connection and fixation of two ends of the to-be-tested joint connector and a pin shaft structure part through the arrangement of a corresponding pedestal, a lower support, a connection slot, a side support and a top seat, thereby achieving the transmission of a force, and achieving the testing of the strength of the to-be-tested joint connector. The corresponding longitudinal loading device, the center plate longitudinal loading device, the vertical loading device, the vertical corner loading device and the transverse corner loading device are matched to realize strength tests of different parts, and meanwhile, the tests can be combined and integrated. Compared with the prior art, the joint connector strength test device has the advantages of being simple in structure, convenient to install and dismantle and capable of efficiently completing simulation ex
