摘　　要：随着中国航空事业的发展,航空疲劳与结构完整性成为影响飞机结构寿命、安全性、可靠性的关键问题之一。经过多年来的努力,飞机结构从最初的静强度、安全寿命设计理念逐渐发展成以疲劳与结构完整性为指导的研制理念和方法,并在型号中取得了成功应用,使得新一代飞机结构的使用寿命、可靠性和经济性得到很大的提升。随着技术的发展和新型号的研制需求,这一领域又出现了许多亟待解决的新问题。本文从航空工业角度梳理了自2000年以来中国航空结构疲劳研究的进展和主要成果,重点介绍了在航空材料/结构/工艺、分析评估理论研究、疲劳试验技术以及飞机寿命管理等方面的研究进展和应用概况,在此基础上从型号研制及工程发展角度提出了对中国航空疲劳需要重点关注的研究方向的建议,以期为中国航空结构技术发展提供借鉴。In China,as the improvement of aeronautical industry,fatigue and structural integrity become one of the key problems that affect the life,safety and reliability of aircraft structures.After years of hard-working,aircraft design philosophy evolved gradually from static strength to safe-life,and now to fatigue and structural integrity as a guide.Aircraft structural integrity program has been implemented successfully into structural development for several new types.The service life,reliability and economy of the new generation aircraft structure have been improved significantly.However,with the improvement of aeronautical technology and the development requirements for new aircrafts,many new problems emerged in this area.From the perspective of aeronautical industry,this paper combs the progress and main achievements of aeronautical fatigue research in China,and focuses on the research status and engineering applications in the aspects of material/structure/process,analysis and evaluation method,fatigue test technology and service life management since 2000.Finally,some aeronautical fatigue research directions need to be focused on were proposed in order to provide reference for the further development of domestic aeronautical structures.
