摘要

飞行器在服役时面临着复杂的动载荷环境,其测量成本较高且难以通过直接测量的方式获取。基于动响应信息来识别动载荷已成为获取结构输入的可行方案。本文从“认知、测量、识别”三方面系统性对飞行器动载荷识别问题进行整理。首先,分析了飞行器机翼、尾翼、舵面、机身、起落架等典型位置处的载荷特征,为后续的响应测量技术选取和动载荷识别方法确定提供必要的先验信息。其次,总结了飞行器结构响应的主要测量技术、应用场景及其优缺点。然后,回顾了飞行器动载荷识别方法的研究进展。最后,探讨了飞行器结构动载荷特征、测量及识别领域面临的主要挑战及未来发展趋势。

Abstract

The aircraft often faces a complex dynamic load environment during service, and its measurement cost is high and difficult to obtain by direct measurement. Dynamic load identification based on dynamic response information has become a feasible solution to obtain structural input. In this paper, the dynamic load identification problems of aircraft are reviewed from three aspects: "cognition, meas-urement and recognition". Firstly, the load characteristics at typical positions such as wings, tail, rudder surface, fuselage, and land-ing gear of the aircraft are analyzed, which provides necessary prior information for the subsequent selection of response measure-ment technology and the determination of dynamic load identification methods. Secondly, the main measurement techniques, applica-tion scenarios, advantages and disadvantages of aircraft structural response are summarized. Then, the research progress of aircraft dynamic load identification method is reviewed. Finally, the main challenges and future development trends in the field of dynamic load characteristics, measurement and identification of aircraft structures are discussed.
