Abstract
Designing a car bumper beam and successive analysis on how it affects the parameters such as shape, thickness and materials will help in enhancing the beam strength at the same time brings a reduction in weight. This also provides a way of using materials that are recyclable and biodegradable which help in controlling environmental pollution. In this paper, main parameters considered are shape, thickness, material and collision conditions, are premeditated for the analysis on an automotive bumper beam to enhance the properties of the beam particularly to stand against the impact forces of crash, ranging from medium speed to high speed impact collisions. Analysis on the bumper beam is performed on composites and conventional materials such as steel, aluminum and magnesium and comparison of the results of the impact behavior of the bumper beam are studied. This study is centered on the selection of bumper beam under varying parameters such as shape and material to cater the needs of safety during the stage of product design specification (PDS). From this work, it had been observed that simple C-section has less stress values than that of other cross- section studied in this research. In the case of double C-section is observed that the stress values are a bit more than the simple C-section but the strain energy is increased by 4.5%. Impact analysis have been performed and compared their results with analytical results.
