Abstract

The invention relates to the field of helicopter upper platform testing and particularly relates to an upper platform fatigue test loading device. The device includes a loading tray (1), a loading shaft (9) and a loading support (10). A plurality of loading fork lugs are arranged on the loading tray (1). The loading fork lugs comprises an My right loading fork lug (2), a Fx loading fork lug (3), an Mz right loading fork lug (4), an Mx front loading fork lug (5), an Mz left loading fork lug (6), an My left loading fork lug (7) and an Mx rear loading fork lug (8). The device realizes loading along X, Y and Z directions. The device realizes boundary simulation in an upper platform fatigue test and applies a load to the upper platform according to test demands. Through the loading point structure design on the loading tray (1), all test loads are applied through less loading action. The device has a simple structure and is easy to assemble and disassemble.

Description

technical field [0001] The invention relates to the field of helicopter upper platform tests, in particular to a loading device for upper platform fatigue tests. Background technique [0002] The upper platform is an important load-bearing part of the helicopter. In order to grasp the fatigue life of the upper platform, fatigue tests must be carried out on the upper platform to obtain the fatigue characteristics of the upper platform, and then give the life of the upper platform. During the test on the upper platform, a total of 6 loads in the X, Y, and Z directions must be applied to the test piece at the same time, and the test load is complicated. At present, there is no similar test device at home and abroad. Contents of the invention [0003] The object of the present invention is to provide a loading device for upper platform fatigue test to solve the problem of simultaneously satisfying the load boundary conditions of the upper platform and simulating the load born...
