The influence of crash initiator placement towards the application of energy crash box due to impact load

Crash box is one of the passive safety systems located between the bumper and main frame of the vehicle. The main function of the Crash box is to absorb energy due to collisions or collisions experienced by vehicles. Crash box has various forms of diverse cross sections. Although it has a cross-section of diverse, however opportunities to improve the energy absorption in a crash box is still quite high. One of them is given a crash initiator. Crash initiator Air the potential to increase the value of energy absorption. The purpose of this study is to analyze the effect of crash initiator on the absorption of crash box energy due to impact loads. This study targets the development of the value of energy absorption effectively by providing crash initiator equalization. The achievement of initial research is to provide equalization of the crash initiator using the finite element method through ANSYS software with the Geometry of the crash box used circle, hexagonal, and origami trapezoid. Each type of crash box is given equal distribution of crash initiator to increase the absorption of energy obtained after getting an impact load. Furthermore, an experimental study to compare the values obtained between simulation and experiment.
