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, measurement and identification”. Firstly, the load characteristics at typical positions such as wings, tail, rudder surface, fuselage, and landing gear of the aircraft are analyzed, which provides necessary prior information for the subsequent selection of response measurement technology and the determination of dynamic load identification methods. Secondly, the main measurement techniques, application 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.}
