MODELLING AND ANALYSIS OF A CAR BUMPER USING VARIOUS MATERIALS BY FEA SOFTWARE

Bumper is an important part which is used as protection for passengers from front and rear collision. The intend of this study was to investigate the structure and material employed for car bumper in one of the car manufacturer. In this study, the most important variables like material, structures, shapes and impact conditions are studied for analysis of the bumper beam in order to improve the crashworthiness during collision.The simulation of a bumper is characterized by impact modeling using Pro/Engineer, impact analysis is done by SOILD WORKS according to the speed that is 13.3 m sec-1 (48 km h-1) given in order to analyze the results. This speed is according to regulations of Federal Motor Vehicle Safety Standards, FMVSS 208- Occupant Crash Protection whereby the purpose and scope of this standard specifies requirements to afford impact protection for passengers. In this research, analysis is done for speed according to regulations and also by changing the speeds. Simulation using Finite Element Analysis software, which is SOILD WORKS, was conducted. The material used for bumper is ABS Plastic ands2 Glass Epoxy.
