Abstract: Vehicle accidents are a growing concern in
today's society. To address this issue, extensive research
has been conducted to determine the most effective
design for the crash box, a passive safety element. In
this study, the performance of cylindrical, square and
hexagonal crash boxes has been extensively
investigated to determine the optimal choice for a given
area. To evaluate the crash boxes, specific energy
absorption and crush reaction force were considered as
evaluation criteria. Energy absorption of the cylinder
design, it provides less energy absorption than the
square and hexagonal design. It produces much less
peak reaction force than the square and hexagonal crash
box. The amount of compression is also much less than
square and hexagonal.
