Abstract

In serving the best in fuel efficiency, the improvement of passenger car in term of lightweight, shape and impact energy absorption of impact beam are considered in conjunction with problems and safety issues nowadays. This report presents the findings of a need on designing and making analysis on the types of aluminum alloy car side door impact beam that can be sustained the maximum load using Finite Element Analysis (FEA) software instead of studying the impact energy of aluminum alloy compared to high strength steel. By having fully understanding of the stress and deformation due to bending on the impact beam, FEA software and bending theoretical formula can be applied together with impact testing done on both aluminum alloy and high strength steel in order to analyze the energy absorption and temperature effect. From the results, aluminum alloy is lighter and have higher impact energy absorption compared to high strength steel with square hollow cross sectional as the most appropriate shape to be used due to highest maximum load that it can sustained. Besides, the impact energy absorption for both materials does not affected by temperature change. The particular strength of this study is in providing insight into the current use of aluminum alloy as impact beam and its future potential in car manufacture.
