Based on the requirements for structural health monitoring of spacecraft,the application progress of guided waves is descirbed from three aspects of space debris impact localization,structural damage assessment and leak localization.Firstly,the risks and monitoring needs faced by structures such as space stations,reusable launch vehicles,and fuel storage tanks are analyzed.Then,the relevant theories and monitoring methods are introduced,as well as multi-physical field guided wave modeling and propagation simulation technologies.Finally,the conceptual design of integrating a multifunctional structural health monitoring system with"collision,leakage and damage"is discussed.And the future applications of guided wave structural health monitoring technology are also prospected,including its integration with space robots,space laser tracing,wireless communication,and energy transmission.
