摘　　要：轻量化是目前汽车发展的趋势,自冲铆连接将成为轻型汽车制造的关键技术之一。从工艺过程和强度评估两方面简述了近年来自冲铆连接技术的发展情况。讨论了现有自冲铆研究的成果和不足,指出了未来自冲铆研究的发展方向,对我国新一代轻型车身铆接装配技术的开发具有指导意义。Self-piercing riveting is becoming one of the key technologies in lightweight vehicle manufacturing. In this paper, a review on the recent developments of the technology, in particular, the piercing/riveting process design and joint strength evaluation is presented. Both the results and the inadequacies of the current research on self-piercing riveting technology are disacussed. The trend of research on the technology is also pointed out.
