摘要
针对大型飞机全机静力试验中承载结构大变形特征，提出了一套完整的飞机大变形结构强度试验方案，开展了大变形试验误差分析和试验系统设计要求研究，突破了试验件载荷处理、飞机支持、载荷施加、配平设计、姿态修正等关键技术，最后以某型飞机大变形试验工况为研究对象完成了试验技术的应用与验证。试验结果表明，提出的试验方案科学合理，可以精确完成机翼大变形状态下考核结构的强度验证，验证了技术方案的有效性，为大型飞机大变形试验技术标准化提供了重要参考。
Abstract
Aiming at the large deformation characteristics of the load-bearing structure in the full-scale static test of large aircraft, a set of structural static test schemes for aircraft with large deformation was proposed. Research on error analysis and test system design requirements for large deformation test of full-scale aircraft was carried out, and the key technologies such as load process, aircraft support, load application, load balancing design and attitude revised were also broken through. Finally, the application and verification of test technology were completed based on the large deformation test condition of one certain type of aircraft. The test results show that the proposed test scheme is scientific and reasonable, and can accurately apply the test load of the assessment structure under the large deformation of the wing, verifing the effectiveness of the technical scheme. The results can also provide important references for the standardization of large deformation test technology for large aircraft.关键词
