Abstract
The bumpers are provided in the front and the backside of a vehicle, which plays an important role during low-speed impacts by acting as a low-speed energy absorber. In this paper, experimental and numerical investigations for three different bumper beams having different geometries, to be proposed for Indian passenger cars are discussed. The strength of these bumper beams in elastic (static) mode is investigated with energy absorption capacity. Experimentations for three quasi-static 3-point bending tests as well as its static FEA based numerical simulation are presented and validated against experimental results. Based on the results, the bumpers are proposed for the Indian passenger cars.
