Abstract

The application belongs to the field of verification test of an engine thrust transmission structure, and particularly relates to a testing device and method for load distribution of a shear pin; thetesting device for load distribution of the shear pine includes a test board. The test board includes a body, a first shear pin hole, a second shear pin hole, four connection bolt holes and strip-typethrough holes, wherein the side face of the body is provided with a rectangular groove, the first shear pin hole, the second shear pin hole, the four connection bolt holes and the strip-type throughholes are formed in the body of the rectangular groove, the strip-type through holes at the vertical-direction top and horizontal-direction left and right portions of the first shear pin hole and at the vertical-direction bottom and horizontal-direction left and right portions of the second shear pin hole are disconnected to form test beams, wherein the upper and lower portions are each provided with one test beam, and the left and right portions are each provided with two test beams. According to the testing device and method for load distribution of the shear pin, the strain output can be adjusted according to the bearing load condition and the sensitivity requirements, and the test resolution and the test accuracy are improved. Moreover, complete simulation of the stiffness and strengthof a tested structure can be maintained without changing a basic structure form of the tested structure, and the test accuracy is improved.

Description

technical field [0001] The application belongs to the verification test field of engine thrust transmission structure, and in particular relates to a shear pin load distribution test device and a test method. Background technique [0002] The pin connection structure is a widely used connection form. The connection structure between the aero-engine and the aircraft needs to meet the requirements of light structure, easy disassembly and maintenance, and at the same time, it needs to ensure sufficient strength to ensure the reliable connection and safety of the engine. It is necessary to accurately ensure that the stress on each part of the connection structure is uniform and reasonable, especially for load-bearing shear pins, using multiple shear pins, whether the load distribution is reasonable, whether it is uniform, and whether it meets the requirements of the damage safety structure design requires accurate The bearing load of each shear pin is tested to understand how th...
