本文介绍了民用飞机机身壁板环向对接结构以细节疲劳额定值法为基础的疲劳分析方法。民用飞机设计要求适航条款相关适航条款:CCAR25-§25.571,条款内容详见引用文件CCAR-25-R4。设计服役目标寿命分析部位的疲劳裕度应满足飞机短、中、远程设计服役目标寿命的要求。民用飞机机身环向对接典型结构飞机机身环向对接典型连接结构如图1所示。
In this paper, the fatigue analysis method based on the detail fatigue rating method is introduced for the circular butt-joint structure of fuselage panels of civil aircraft. Civil aircraft design requirements Airworthiness terms related to airworthiness terms: CCAR25-§25.571, the terms of reference see the reference document CCAR-25-R4. Design Service Target The fatigue life of the life analysis site should meet the requirements of the service life of short, medium and long-range aircraft designs. Civil aircraft fuselage docking docking typical structure aircraft fuselage docking docking typical connection shown in Figure 1.
