The developing concept of traditional bumper is to satisfy low speed collision regulation for protecting body of vehicle. In addition to this regulation. The RCAR (The Research Committee for Automobile Repairs) requires reparability of bumper to reduce repair cost In this paper, the bumper for RCAR was analyzed by impact simulation and compared with regulation bumper to evaluate their crash performance and reparability. Based on this result, bumper structure to improve reparability was conducted.

It is to be classified into friendly environment and safety problems, as a main technology development of the recent automotive industry. As these tendency, lots of automobile companies focus on a reduction of fuel expenses and strengthen of crash safety using high strength steel. In this study advanced technologies such as tailored blanks, aluminum extrusion and high strength steel forming applied to bumper beam will be described. As a result of impact analysis and an actual impact test, in terms of beam performance and a possibility for the mass production will be discussed.

In general, the role of the low-speed vehicle bumper is to absorb the impact during a collision and protect the vehicle with its occupants. In order to evaluate the efficiency of the bumper, each country must follow some domestic and International low-speed bumper impact standards and specifications to determine damaged regions. But it is only a consultation or confirmation and not actually the regulation of the efficiency of the bumper. Most automobiles evaluate the balance of the development stage of the bumper with the resultant price of completion which should not yield to a many difference. In this paper, we propose to automobiles possible conditions for a impact test of the low-speed vehicle bumper with great value results.
