Experimental device for simulating aircraft wing stringer assembly

Abstract

The invention discloses an experimental device for simulating aircraft wing stringer assembly. The experimental device comprises a test table bottom platform, a stringer, skin, and an edge longitudinal positioning device, an edge vertical positioning device, a sliding transverse support force measuring device, a slider transverse positioning device and a sliding vertical clamping device which are arranged on the test table bottom platform and connected with the stringer and the skin. The experimental device has a rational structure, is stable in positioning and can realize the simulation of different machining deformation, clamping positions and clamping force; during the simulation of the aircraft wing stringer assembling process, different machining deformation, different positioning errors, different clamping force and different clamping areas can be simulated by various devices, and the assembling deformation of the stringer when the factors change can be measured, so that the relation between the assembling deformation of the stringer and the variables can be determined, and the law of the aircraft wing stringer assembly can be disclosed. The experimental device for simulating the aircraft wing stringer assembly has the advantages of multiple variable factors and high adaptability.

Description

technical field [0001] The invention relates to the technical field of aircraft assembly, in particular to an aircraft wing truss assembly simulation experiment device. Background technique [0002] In order to accelerate the development of my country's aviation industry, enter the world's advanced ranks, and win a certain market share in the market competition, it is necessary to manufacture high-quality and reliable products. The aircraft assembly is the most important part of the aircraft manufacturing process. It has different characteristics from the assembly of general mechanical products. Because most of the parts of the aircraft wing are large thin-walled parts, deformation is easy to occur during processing, resulting in difficult assembly quality. Therefore, it is an urgent need to invent a test bench that can simulate the assembly of large thin-walled parts of the aircraft wing and reveal its rules. The long stringer is a typical deformable large thin-walled part ...

AI Technical Summary

Problems solved by technology

[0003] After inquiry, the existing aircraft airfoil frame is mainly to improve assembly flexibility or assembly efficiency, but fails to study the deformation law of the assembly process

These jigs are forced to assemble by adding gaskets and other measures to ensure that the parts can be assembled, but they do not pay attention to the law of assembly deformation.
