Analysis of Geometric Variables of the Bumper in the Pedestrian Protrection
One of the main important investigation lines in the automotive industry is automotive safety. Inside automotive safety, the most difficult thing to be reduced is the number of accidents where pedestrians are involved. So, this field must experiment an active research and development activity, trying to reduce possible injuries of the pedestrian in case the accident finally happens. This research project is focused on the behaviour of the lower legform in front of the posible shapes of the front bumper of the car, taking into account external variables. The methodology followed is the comparison with the 3 main criteria used with the legform in pedestrian protection: Z acceleration, share and bending. The results have been obtained after a matrix of tests focused in the stiffnes of the material, the contact position between the bumper and legform and the velocity of the impact. The tools used to achieve the results are the dynamic simulation and testing in the laboratory. A reference bumper and a reference front end have been developed and modelized to have an initial model. The main points of the initial model are the lights supports, the hook position and the bumper and the pedestrian supports.
