Hazwan A. H., M. Haidiezul M. A., M. Nawi W.

The function of this element is to convert the kinetic energy into other forms of energy during a collision that can minimize injuries to the passengers. Therefore, various studies have been reported previously to improve the thin-walled structure to decrease the damage and provide protection for the vehicle and occupant. This study aims to determine the effects of the cutout on the thin-walled tube when impacted under dynamic axial loading. The effects of sizes, shapes, locations, and the number of cutouts on the energy absorption characteristics have been analyzed by using the validated finite element model. The result indicates that a circular tube with a square cutout shape, larger cutout sizes, and near the top-end of the tube has more energy absorption characteristics. Furthermore, the results of energy absorption (EA), crush force efficiency (CFE), and specific energy absorption (SEA) are highest when applying four cutouts on the surface of the thin-walled tube. Research information provided in this study will serve as a guide in designing the cutout thin-walled tube for crashworthiness enhancements in the future. 2022 2022-12-04T03:04:45Z 2022-12-04T03:04:45Z 2022-12 Article Advanced and Sustainable Technologies (ASET), vol.1(2), 2022, pages 76-86 2976-2294 (online) http://dspace.unimap.edu.my:80/xmlui/handle/123456789/77348 https://aset.unimap.edu.my en Penerbit UniMAP (UniMAP Press) |
