A testing method by dropping a weight on test beams was developed in order to obtain dynamically bending strength performance of bumper beams. The load-deflection curves of straight beams, which were made of high tensile strength steel sheet, were measured using this testing method. It was found that the dynamically bending strength performance is not different from the statically bending strength...
This paper presents the reinforced structure of bumper beams with a box cross section and the statically bending strength of its. The structure consists of two hat section beams and a reinforcement plate which is placed inside the box cross section and in the vertical direction of load line. It was confirmed experimentally that the plate is effective to arrest the buckling deformation in the side-wall...
