飞机结构疲劳寿命分析的一些特殊问题

Some Special Subjects of Fatigue Life Prediction on Aircraft Structures

简要介绍了当前飞机结构疲劳寿命分析中遇到的腐蚀疲劳、蠕变疲劳、振动疲劳和复合材料疲劳等特殊问题,回顾了解决这些问题已有的主要处理方法,并介绍了作者的一些研究成果,从疲劳寿命评估方法论的角度,讨论了处理这些问题还需要进行的基本研究。

Some special subjects of the fatigue life prediction on aircraft structures encountered in recent years, such as fatigue under the alternative of corrosion or cyclic loading, creep fatigue of polymethyl methacrylate, fatigue under stochastic vibration loading and cyclic loading, fatigue of fibre reinforced polymers, are reviewed. The main research results on these subiects and results obtained in the recent years in our research group, are introduced. From the point of view about fatigue life estimation the essential points to be investigated for these problems are discussed.
