Finite Element Analysis of Passenger Vehicle Bumper
- Passenger vehicle bumper assembly plays very important role in case of an accident. Automotive industry is a very huge ground and research is still evolving. From this safety of passenger has to be focused on safety and comfortably. In this paper, the most important parameters of an automotive front bumper beam such as material, shape and impact condition are to be studied to improve the stiffness and strength. The strength of the bumper is investigated with energy absorption and impact force in maximum deflection situation. Similar bumper beams made of different materials are simulated to determine the deflection, impact force, stress distribution and energy-absorption behavior; these characteristics are compared with each other to find best choice of material. These designs had been studied by impact modeling using Finite Element Analysis software, LS DYNA to determine the energy absorption by analyzing the kinetic energy, displacement and impact force.
