DEVELOPMENT OF PHYSICAL AND ANALYTICAL SIMULATIONS OF THE AUTOMOBILE CRASH VICTIM

A RESEARCH PROGRAM WAS CONDUCTED WITH THE OBJECTIVE OF DEVELOPING IMPROVED PHYSICAL AND ANALYTICAL SIMULATIONS OF THE AUTOMOBILE CRASH VICTIM FOR USE IN STUDIES OF OCCUPANT RESTRAINT AND PROTECTION. TO THIS END, A REVIEW WAS UNDERTAKEN OF THE STATE OF THE ART OF VEHICLE IMPACT AND SLED TESTING, IN ORDER TO DETERMINE THE ACCURACY AND RELIABILITY OF SUCH ACCIDENT SIMULATION TECHNIQUES. A SURVEY OF HUMAN PHYSICAL PARAMETERS AND A REVIEW OF EXISTING AND DEVELOPING DUMMIES WERE ALSO PERFORMED IN ORDER TO RECOMMEND IMPROVEMENTS TO DUMMY SPECIFICATIONS AND DESIGNS. THESE RECOMMENDATIONS WERE ALSO APPLIED TO THE EXISTING TWO- DIMENSIONAL SIMULATION DEVELOPED BY CORNELL AERONAUTICAL LABORATORY, INC. (CAL). AS A RESULT OF A CONTRACT MODIFICATION, A LIMITED NUMBER OF SLED TESTS WERE CONDUCTED TO EXPERIMENTALLY INVESTIGATE "SUBMARINING" RESPONSES OF A REPRESENTATIVE STATE-OF-THE-ART ANTHROPOMETRIC CRASH TEST DUMMY. THE DYNAMIC INTERACTION OF THE LAP BELT LOADING, PELVIS CONFIGURATION, TORSO STIFFNESS AND REACTION OF THE LOWER EXTREMITIES IN RELATIONSHIP TO THE SUBMARINING THRESHOLD WERE ASSESSED. TWO DIFFERENT PELVIS ASSEMBLIES WERE USED DURING THIS INVESTIGATION. THE FIRST SERIES OF TESTS WERE CONDUCTED USING THE STANDARD PELVIS FURNISHED WITH THE SIERRA MODEL 292-850 DUMMY. THE SECOND SERIES INCORPORATED THE NEW SOCIETY OF AUTOMOTIVE ENGINEERS (SAE) PELVIS. HIGH-SPEED-MOTION-PICTURE COVERAGE OF THE PELVIS AND LUMBAR SPINE WAS USED TO PERMIT STUDY OF INTERACTIONS OF THE BELT LOADING WITH PELVIS ROTATION AND TORSO FLEXIBILITY AND, THEREBY, TO PROVIDE A BETTER UNDERSTANDING OF THE MECHANISM RELATED TO SUBMARINING. SPECIAL INSTRUMENTATION FOR MEASURING THE TIME HISTORY OF THE VERTICAL SEAT REACTION FORCES WAS ALSO DESIGNED AND CALIBRATED. /HSRI/
