Optimized metal foam-filled Crushbox structure to improve the impact energy absorption

Abstract

According to the transport statistics, there are many personal injury affected road fatalities on the EU’s roads. The increasing urbanization results in huge daily crowded paths in the cities. Drivers try to recoup for lost time in traffic jams with increased speed and reduced tracking distance, and the inattentive behavior to using mobile phones is a common cause of rear-end collision.The most common personal injury of the rear-end collision would be decreased by an optimized crumple zone to reduce the impact load force. With mass optimization not only the operational efficiency would be improved but the impact energy can be reeducated also. To achieve this aim integrated and advanced materials must be applied. This study is focusing on the optimization of the bumper-crushbox, and apply an improved structure in which more volume of the metal foam can be utilized, than the recent solutions.
