Loading device for load calibration test of engine hanging installation joint

Abstract

The embodiment of the present invention provides a load calibration test loading device for an engine suspension installation joint, which relates to the technical field of load calibration test loading devices, so as to solve the problem that it is difficult to load the main engine suspension joint and the rear suspension joint with large loads in the prior art. . The load calibration test loading device uses the strain electrical measurement method to measure their flight loads. The device can not only complete the heading and vertical loading calibration of the main suspension joints, but also apply restraint loads on the front support joints and rear support joints. On the suspension joint, the heading and vertical load calibration of the rear suspension joint can be completed, and the restraint load can be applied to the front brace joint and the main suspension joint, which saves a lot of economic cost, time cost and labor cost. The device of the invention has ingenious design, convenient installation and use, easy disassembly and assembly, and can meet the use requirements of multiple sites; the device of the invention can be realized by simple mechanical processing, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of a load calibration test loading device, in particular to a load calibration test loading device for an engine hanging installation joint. Background technique [0002] The engine hanger installation joint is an important force transmission component on the wing. It is used to install the engine hanger (the engine compartment is connected below the hanger), and it is the hub that transmits the engine's gravity and thrust to the wing. A certain type of transport aircraft engine suspension installation joints are divided into front support joints, inner main suspension joints, outer main suspension joints, rear suspension joints, and side tie rod joints, such as figure 1 shown. The front brace joint and the side tie rod joint are connected to the engine suspension through intermediate tension and compression rods, and their loads can be obtained by measuring these intermediate tension and compression rods. ...
