INVESTIGATION OF THE EFFECTS OF EDGE RADIUS ON CRASH PERFORMANCE IN CRASH BOXES

Abstract

Automobiles are the most basic element of the road transportation. The number of automobiles in traffic is increasing day by day thanks to advancing technology. Therefore, the number of accidents is increasing too. For this reason, automobile manufacturers are doing a lot of work on the development of automobile active and passive safety systems and equipment. Crash boxes are a passive safety element used for protecting chassis, passengers, and drivers in an accident. In this study, the effect of edge radius changing on the crash performance of the square section crash box was investigated; the study was conducted as numerical, and ANSYS Workbench software was used. The study started with determining the ideal element size. For this, three different element sizes, 5 mm, 4 mm, and 3mm, were used at existent boundary conditions. After determining the ideal element size, crash performances were investigated through force-displacement and absorbed energy-displacement graphs depending on the edge radius. As a result of the study, the highest crush force was obtained with the crash box with no edge radius. In contrast, among the crash boxes with edge radius, the highest energy absorption performance was obtained with the crash box with a 4 mm edge radius.
