Abstract

Although extruded aluminium bumper beam has been commonly used in advanced car makers, there are not so much precedent for it's localization. For the localization of aluminum bumper beam of 7XXX series, benchmarking, material modifications of 7XXX series aluminum alloy, section design of beam, impact analysis had been performed in this study. High fuel efficiency and weight reduction could be achieved by using aluminum bumper beam of which the weight is lighter than that of steel. Moreover, it is expected to reach higher recycling rate by substituting aluminum for steel.
