摘　　要：新一代先进战斗机对机体平台的要求为轻重量、高承载、长寿命及多功能。为实现这个目标,结构故障预测与健康管理(SPHM)技术是一项亟须解决的关键技术,是实现由传统的事后维修和定期维修转向基于状态的视情维修的重要手段。针对SPHM的主要功能、关键技术和系统设计与研制,本文阐述了强度设计团队近年来在SPHM方面的研究成果、设计实践、技术发展及后续展望。这些技术成果已成功应用于新一代战机SPHM系统的研制。The requirements for the airframe of a new generation of advanced fighter are light weight,high g capacity,long life and multi-function.To achieve this goal,SPHM is one of the key techniques that need to be solved,and also an important means to realize on-condition maintenance from the traditional breakdown maintenance and regular maintenance.This paper describes the research results,design practice and technical developments in SPHM by the strength team in recent years,which include the main function,key technologies and system designs of SPHM.These research results have been successfully applied to the development of a new generation of high performance fighter airframe.
