DEVELOPMENT OF ORIGAMI PATTERNED CRASH-BOX FOR BI-FUEL VEHICLE
Axially crushed thin-walled structure that is usually used for impact energy absorption is expected to collapse in a progressive stable manner. However, the collapse process is frequently disturbed by a premature bending that sees the failure of the structure that leads to poor energy absorption. This occurrence of premature bending is due to several factors such as poor design parameter and substandard fabrication of the thin-walled structure.
To diminish the phenomenon of premature bending, a method of applying origami pattern to the wall of the thin-walled structure was seen beneficial, as the origami crease lines would be the guiding lines for the progressive collapse. Several studies have shown positive results where the amount of energy absorption is increased with the origami pattern application, specifically with Yoshimura origami pattern, which has similar pattern with the collapse mode pattern of thin-walled structures. Nevertheless, the relations between the origami pattern parameter configurations with the dynamic axial crushing are not well comprehended, thus, it will result to a costly design iteration.
