| 摘 要： | 该文选用6061和2A12航空铝合金薄板材料，进行自冲铆接和超声自冲铆复合连接试验，基于拉伸-剪切和电子显微镜测试，研究超声自冲铆接成形性及力学行为。结果表明：超声自冲铆接头较自冲铆接头的内锁量提升了44.8%；其钉头高度下降了34.4%；超声自冲铆接头的静载强度提升了18.1%，缓冲吸震性能提升了17.5%；超声焊接致使自冲铆接头的铆钉颈部与上板接触区域、铆钉腿部与上板接触区域形成固相焊；超声焊接可有效提高自冲铆接头的稳定性。

| Abstract: | 6061 and 2A12 aerospace aluminum alloy sheet materials are selected to conduct self-piercing riveting and ultrasonic self-piercing riveting composite joining tests. Based on tensile-shear and electron microscope tests, the forming quality and mechanical behaviors of ultrasonic self-piercing riveting are studied in this paper. The results show that the interlock of the ultrasonic self-piercing riveting USPR joint is increased by 44.8% compared with that of SPR joint; the height of rivet head is reduced by 34.4%; the static strength of the USPR joint is increased by 18.1%, and the shock absorption performance is increased by 17.5%; the welding causes the contact area between the rivet neck and the upper plate of the self-piercing riveting joint, and the contact area between the rivet leg and the upper plate to form solid phase welding; ultrasonic welding can effectively improve the stability of SPR joint. |
