DEFORMATION CHARACTERISTICS OF CARS IN TESTS TO SIMULATE PEDESTRIAN IMPACT
IMPACT TESTS WITH A RIGID INDENTER SHAPED TO REPRESENT THE HUMAN BODY WERE CARRIED OUT TO DETERMINE THE LOAD-DEFLECTION CHARACTERISTICS OF CARS IN THE AREAS LIKELY TO BE INVOLVED IN PEDESTRIAN-CAR FRONT END ACCIDENTS. FIVE RECENT MODEL CAR BODIES, MOST OF WHICH HAS A NARROW HORIZONTAL EDGE AT ABOUT HIP HEIGHT, WERE STRUCK BY AN INSTRUMENTED INDENTER AT VELOCITIES OF 16 AND 24 F.P.S. PEAK FORCES UP TO 3000 LBF WERE RECORDED. THE DEFLECTION AT 1000 LBF WAS GENERALLY LESS THAN 0.4 IN INDICATING THAT ENERGY ABSORPTION BY THE VEHICLE, WHICH COULD REDUCE THE FORCES APPLIED TO THE HUMAN BODY, WAS NEGLIGIBLE. A COMBINATION OF BLUNTER SHAPE AND LOWER STIFFNESS IN THE AREA LIKELY TO STRIKE THE HIP OF A PEDESTRIAN WOULD MITIGATE THE INJURIOUS EFFECTS OF IMPACT. /AUTHOR/
