Abstract:Static strength verification of civil aircraft body structure is the basis of ensuring the safety of aircraft structure, and the basic condition for civil aircraft to obtain the type certificate and put into market operation. Starting from the process of structural static strength verification, this paper describes the current ideas, methods and future trend of structural static strength verification from aspects of analysis and test. For metal structural static strength, it is a better engineering approach for the static strength airworthiness verification to use the comprehensive static strength verification by the analysis of the test verification combined with some necessary tests, while the “building-block” method for composite structure is currently the optimal verification scheme. The traditional method of internal force model and engineering analysis is still the main solution for structural static strength verification, but the working process, mainly the part of the strength verification, will develop towards automation to meet the requirements of efficiency and quality in actual engineering analysis. Meanwhile, the whole aircraft fine finite element model analysis is an important auxiliary method to verify the structural static strength, which represents the future development direction in aircraft structural strength analysis.
