Crash boxes, one of the components of passive safety systems, will ensure that damage is minimized in the event of an accident. In this study, the impact on the crash performance of the corrugated on the crash box was investigated using the finite element method. Crash box designs with different corrugate widths were modeled. The widths of the corugate were determined as 1 mm, 2 mm, 3 mm, 4 mm and 5 mm, and were opened at different numbers on the crash boxes. The wall thickness of each crash box is taken as 2 mm. Designed crash boxes are divided into finite elements with Hypermesh program, Ls-PrePost program has been used to determine material cards, properties such as contacts and boundary conditions and dynamic analyses were carried out with Ls-Dyna. As a result of the analyses made, it has been found that corrugate on crash boxes has a positive effect on crashworthiness performance.
