Design of frontal longitudinal for enhancement in crashworthiness performance

Abstract

Abstract The increase in the number of vehicles due to increase in population leads to an increase in the number of accidents. To find a design that keeps occupants as safe as possible by enhancing the energy absorption capabilities and hence decreasing the number of fatalities is taking place. Non-linear finite element is used in this study to predict new design performance and to compare with other conventional S-shaped designs. It was shown that the proposed design increased the specific energy absorption (SEA) by 265% in comparison with the conventional S-Shaped frame design with octagonal geometries and increased in SEA 16% of the S-Shaped with foam filled-square cross-sectional. In this study, the specific energy absorption will take in consideration the energy absorber used is made of mild steel.
