为了探究电磁铆接技术在碳纤维复合材料上的可行性,采用碳纤维-铝合金结构为研究对象。探究了碳纤维-铝合金电磁铆接接头的干涉量及剪切、拉脱性能,并与传统准静态压铆技术进行了对比。结果表明:无论是Φ4 mm铆钉,还是Φ6 mm铆钉,电磁铆接结构相对干涉量不仅均匀性更好,而且平均值更高,分别从4.96%提升到5.20%,6.85%提升到7.85%;电磁铆接接头剪切性能有较大提高,对于Φ4 mm铆钉和Φ6 mm铆钉,电磁铆接最大剪切力相比准静态压铆分别提高了19.7%和5.2%;电磁铆接接头拉脱性能有较小提高,对于Φ4 mm铆钉和Φ6 mm铆钉,电磁铆接最大拉脱力相比准静态压铆提高了3.9%和6.6%。结果说明电磁铆接技术更适合复合材料的连接。
In order to explore the feasibility of electromagnetic riveting technology on carbon fiber composites, the use of carbon fiber - aluminum alloy structure as the research object. The interference, shear and pull-off performance of carbon fiber-aluminum alloy electromagnetic riveted joints were explored, and compared with the traditional quasi-static riveting technology. The results show that the relative interference of electromagnetic riveted structure is better than that of Φ4 mm rivet or Φ6 mm rivet, and its average value is higher, from 4.96% to 5.20% and 6.85% to 7.85% respectively. Compared with quasi-static riveting, the maximum shearing force of electromagnetic rivets increased by 19.7% and 5.2% respectively for Φ4 mm rivets and Φ6 mm rivets; the pull-off performance of the electromagnetic riveted joints was slightly increased, For Φ4 mm rivets and Φ6 mm rivets, the maximum pull-out force of electromagnetic rivets is 3.9% and 6.6% higher than quasi-static rivets. The results show that electromagnetic riveting technology is more suitable for composite connections.
