Abstract

The crashworthiness of daily passenger vehicles has been continuously developed to improve the safety of a passenger on collision. This study presents a simulation on thin-walled foam filled crash-box based on finite element methods to improve the current crash box design while also maintaining the usage of simple geometry in form of rectangular tube. This crash box is modeled as foam filled thin-walled structure that is intended to be mounted on the frontal side of car chassis. This simulation was carried out using frontal impact test, with an impactor speed of 10 m/s. The foam-filling of the crash-box is created in-house by the researcher, using calcium carbonate blowing agent on melt route process. By observing the area under the curve of the relationship between the force-reaction and the displacement, the energy absorption can be calculated. The simulation also reveals the deformation patterns on the crash box. The result of the simulation shows that foam-filling on thin-walled crash box improves the deformation behavior of the crash box and subsequently improving the energy absorption figure and its crushing force efficiency.
