【摘要】：复合材料机械连接件的疲劳问题在飞机结构设计中愈显突出。以复合材料层合板疲劳中刚度退化模型为基础,分析了复合材料单钉连接件在疲劳过程中细观机理,建立了复合材料单钉连接剩余强度预测公式;并开展了CCF300/BA9916-ⅡS复合材料单钉连接疲劳试验。结果表明,公式预测结果与试验结果取得较好的吻合。
[Abstract]:The fatigue problem of composite mechanical connectors is becoming more and more prominent in aircraft structure design. Based on the stiffness degradation model of composite laminated plate during fatigue, the meso-mechanism of composite single nail joint during fatigue is analyzed, and the prediction formula of residual strength of composite single nail connection is established. The fatigue test of single nail joint of CCF300/BA9916- 鈪，
