Finite element analysis of bumper beam with thickness variation based on natural fibre composite material
Keywords:
Finite element, Bumper beam, Material CompositeAbstract
Composite material consists of several materials. Currently, composite materials, such as bumper beams, have been widely applied in the automotive field. Natural fibres that are more environmentally friendly are one of the factors for making composite materials, one of which is coconut fiber bamboo fiber with epoxy matrix which has been done by previous researchers. In this study, finite element analysis was carried out, namely, von Misses stress, deformation, safety factor, and comparison of bumper weight between bumper beam steel weight. The results of the analysis obtained the highest Von misses stress at a thickness of 3 mm bumper beam of 7.0908 Mpa. The results of the study on the deformation obtained by the 3 mm bumper beam is 1.0575 mm. The results of the safety factor analysis obtained on the bumper beam thickness of 6 mm and 9 mm are 15,000 safety factors. The results of the study of the weight comparison of the bumper beam at a thickness of 3 mm, 6 mm, and 9 mm can reduce the weight by 85.37%, 68.48%, and 52.82%.
