Abstract

The invention belongs to testing technologies, and relates to a testing apparatus for testing the damage tolerance capacity of wall panels of airplanes. The testing apparatus comprises a loading device. The loading device comprises a fatigue testing machine (1). The testing apparatus is characterized by further comprising a non-contact strain and displacement measuring instrument (2), a non-contact strain and displacement measuring instrument support (3), a digital microscope reading system (4), a digital microscope reading system support (5), an infrared thermal imager (6) and an infrared thermal imager support (7). The testing apparatus for testing the damage tolerance capacity of the wall panels of the airplanes has the advantages that the applicability of the testing apparatus can be improved, and testing requirements on the damage tolerance of wall panel structures of the airplanes can be met.

Description

technical field [0001] The invention belongs to testing technology, and relates to a test device for testing the damage tolerance performance of aircraft wall panels. Background technique [0002] Thin-walled structure is one of the design units commonly used in aircraft manufacturing. The strength standard of early aircraft structures was static strength and stiffness. Nowadays, it is required that the aircraft structure can still bear sufficient load and work until the next maintenance when there are cracks or local parts are damaged. , which requires the aircraft design to meet the damage tolerance design requirements. The damage tolerance performance test of thin-walled structures, especially aircraft panels, can provide important basic data for the damage tolerance design of aircraft structures, and it has attracted great attention from aircraft design and manufacturing units. Most of the current damage tolerance test devices can only record a certain specific fracture...
