Abstract

Abstract: Panel tests are an important part of the building block verification process for aircraft development.Due to the complex stress on panels, the actual load form and boundary conditions should be comprehensively considered in the panel test.The complex load test technology is an inevitable choice to simulate the real stress and boundary constraints of aircraft panels.Therefore, domestic and foreign researchers and institutions have conducted extensive research and development work on the panel test technology and facilities, effectively reducing the cost of the test and verification, shortening the development cycle of aircraft, and strongly supporting aircraft design and verification.Based on the stress analysis of civil aircraft panels, this paper summarizes and analyzes the complex load test technology of aircraft panels, including mainly the compression-shear load test technology of flat panels, the combined shear/air pressurization and axial tension/compression load test technology of curved panels, as well as the general anti-coupling and anti-interference problems in the process of combined load application.In addition, three kinds of curved panel test facilities representing the advanced level of the panel testing technology are analyzed and reviewed.Finally, the development status of the complex boundary load test technology for aircraft panels is summarized and prospected.
