摘　　要：天地往返运输系统中贮箱设计的核心问题是其可重复使用性。贮箱重复使用性必须通过提高结构耐久性来获得,而耐久性提高必须基于对贮箱结构的健康状况有足够的认识,需要采用先进传感器技术和无损检测评价来确认贮箱结构的功能完整性和健康状况。针对可重复使用贮箱在飞行过程中的温度分布、应力分布、损伤演化及外部撞击等,论述了可重复使用贮箱失效模式与健康监测策略,集成化健康监测和诊断技术及其相应体系构架,实现贮箱的状态监测、损伤监测和外部撞击监视,为贮箱的安全、正常工作提供保障。The core problem of tank design in the Space Transportation System is its reusability.The reusability of the tank must be achieved by improving the durability of the structure,and durability enhancement must be based on the sufficient understanding of the health status of the tank structure.Advanced sensor technology and non-destructive testing and evaluation are needed to confirm the functional integrity and health status of the tank structure.Aiming at the temperature distribution,stress distribution,damage evolution,external impact and so on of reusable tank in flight,the failure mode and health monitoring strategy,the integrated health monitoring and diagnosis technology of reusable tank are discussed,also its corresponding system architecture,which can realize the monitoring of status,damage and external impact,guaranteeing for the safe and normal work of tank.
