Parameter optimization of an upper beam support for pedestrian safety

With people paying more attention to the performance of automotive safety, car manufacturers continue to improve the vehicle itself. In this paper, several design laws are concluded by improving the legform to bumper tests of a SUV. When the height of lower bumper reference line is between 425mm and 500mm, the upper legform test can be chosen instead of the lower legform test. Meanwhile, based on the suitable package for deformation of the legform, the performance of legform can be achieved by optimizing the padding. This principle could also be taken as a reference in legform impact design of SUV type of vehicle.
