Abstract
This project thesis addresses the applicability importance of design and analysis the aluminum/steel column due to transverse loading, as well as side door impact beam in automotive industry. During the side impact collision the distance between the point of impact and the occupant is much smaller, and thus by mounting an impact beam at the side door of the car will tend to improve the passengers' safety and increase the chances of survive during a fatal car crash on the road. The impact beam should be designed to have the ability to absorb as much deformation energy as possible without breaking, while also possessed of low structural weight and high structural stitiness to reduce the additional weight of the beam in a vehicle. During the investigation, an experimental of tensile test using Universal Testing Machine (UTM), as well as numerical finite element (FE) analysis was performed to obtain the mechanical properties of the column. Good verifications were found between the FE analysis and experimental data in tensile test and have proved the veracity of numerical FE analysis. The effect of transverse loading on the buckling behavior and energy absorption of a colum under quasi-static condition was numerically investigated, while also further extended to the design and analysis of the new impact beam. Upon completing the FE analysis, the results will be compared in terms of impact energy absorption, buckling behavior and stress analysis of the columns. Finally, results were testified that the new design of impact beam has possessed the lighest energy absorption in comparison to other standardized columns.
