Experimental Simulation of Car/Pedestrian and Car/Cyclist Collisions and Application of Findings in Safety Features on the Vehicle 890751

In order to reduce the severity of injuries to pedestrians and cyclists, the sheetmetal contact zones of Mercedes-Benz cars are constructed of a yielding, smooth-surfaced design. Unfortunately, contradictory demands are made on some components. This is particularly true for the bumper in which avoiding or reducing the cost of repair requires a greater bumper height, overhang, and stiffness, which run counter to the requirements of pedestrian protection. Despite this conflict, however, the bumpers of recently developed Mercedes-Benz cars offer a high degree of pedestrian protection since they are faced with rigid foam. To assist in both mathematical and experimental pedestrian impact simulation, standard test dummies should be modified by reducing the stiffness at the waist in order to achieve a higher degree of faithfulness to human behaviour.
