Abstract

Impact is the action of one object coming forcibly into contact with another. In term of vehicles, there are different point of impact on the car such as frontal, side and rear but the most severe crash happens from the frontal impact and then from side impact. Bumper is one of necessary part in passenger vehicle as it is the main tool to damp the energy from crashes. Therefore, this study was carried out to investigate how energy absorbed for the front bumper from different angle of impacts 0˚, 30˚, 45˚ using Finite Element Analysis (FEA). The velocity 80 km/hr is identified for the impactor and not to change through the analysis. For the material and design of the bumper it is decided to be a metal bumper as the beginning stage before studying the real material with the design of a GEN 2 front bumper. During the simulation, the meshing used is the tetrahedral type with the element size of 30 mm for all mesh in bumper and impactor. The results showed that the amount of energy absorption increase while the amount of the displacement decrease with the increase of impact angles.
