摘要
飞机使用中经常会遇到因为结构振动而产生的疲劳破坏现象。飞机结构的振动疲劳分析是进行飞机结构动力学设计的重要设计分析手段。本文通过对国内外几十年来形成的主要的振动疲劳分析方法进行了归纳整理,为飞机设计和维修提供振动疲劳的设计与分析技术支持。
The fatigue failure caused by the structure vibration of aircrafts in flight often comes forth. Vibration fatigue analysis plays an important role in structure dynamics design. In order to design and maintain an aircraft with vibration fatigue technique, all kinds of estimation methods for fatigue life, frequently used in recent yeas, are reviewed in this paper.
