摘要: 针对金属/复合材料电子束毛化连接的疲劳问题,本文进行了金属/复合材料电子束毛化连接试验件的疲劳特性研究,分析了不同疲劳载荷水平下毛化接头的疲劳特性和破坏模式。研究结果表明毛化连接件的疲劳寿命主要受限于金属毛刺的疲劳寿命,对所选的材料及构型,其疲劳载荷次数达到1 × 106次,对应的载荷水平为强度极限的25%。
Abstract: Aiming at the fatigue problem of Comeld joints, the fatigue characteristics of Comeld joints were studied, and the fatigue characteristics and failure modes of Comeld joints under different fatigue load levels were analyzed. The results show that the fatigue life of Comeld joints is mainly limited by the fatigue life of metal burrs. For the selected materials and configurations, the number of fatigue loads reaches 1 x 106 times, and the corresponding load level is 25% of the strength limit.
