Abstract
Recently, mechanical joining processes have received much attention for joining multi-materials. In particular, these processes have a great demand in the automobile industry for weight reduction. The press-fitting process is a representative mechanical joining process. In this process, the shape of the interfacial serration on the joining plane is very important because it has a significant effect on the joining strength. In this study, the characteristics of the aluminum–steel press joining process were investigated according to the shape of the interfacial serration of the joining plane. The deformation of the material and the forming load were investigated by conducting finite element analysis. In addition, the unfilled height of the material, joining force, and torque were measured experimentally.
Highlights
Transporting machines, such as automobiles and aircraft, are made up of numerous parts.Automobiles are assembled using more than 10,000 to 30,000 parts [1]
The development of ultra-high-strength steel has been actively carried out, and many studies have been recently conducted on the application of lightweight materials such as aluminum, magnesium, and carbon fiber composites [3,4,5,6,7]
In order to investigate the effect of the serration angle, further research is needed in first because of the low material flow restriction caused by the wide cavity in the groove
Summary
Transporting machines, such as automobiles and aircraft, are made up of numerous parts. Automobiles are assembled using more than 10,000 to 30,000 parts [1]. The development of ultra-high-strength steel has been actively carried out, and many studies have been recently conducted on the application of lightweight materials such as aluminum, magnesium, and carbon fiber composites [3,4,5,6,7]. Various studies are being carried out on the joining processes to combine steel and lightweight materials in accordance with the expansion of the application of lightweight materials. Lightweight automotive construction depends on the lightweight materials and on suitable joining methods for multi-material combinations with high process reliability [8]
