Self-Piercing Riveting을 이용한 알루미늄 합금과 Steel 강판의 다층 접합 연구
Abstract
Recently, several studies have been conducted in the automotive industry with the aim of improving fuel efficiency. In particular, lightweight materials have proved effective in improving both the performance and fuel economy of cars. In this study, we have investigated the joining of aluminum alloys (that are increasingly being used as lightweight materials in vehicles) using self-piercing riveting (SPR). Three sheets of the material were joined using SPR. The joining strength was assessed via a shear strength test. When the mechanical properties of the upper plate were constant, the shear strength increased with an increase in the mechanical properties of the intermediate plate. Evaluation of the joining strength with respect to the order of combination of the top and intermediate plates revealed a higher shear strength when the intermediate plate is stronger than the top plate.
