UNDERRIDE/OVERRIDE OF AUTOMOBILE FRONT STRUCTURES IN INTERVEHICULAR COLLISIONS-VOL 2-CAR-TO-CAR HEAD-ON IMPACTS- FINAL REPORT

FINDINGS FROM STUDIES AIMED AT REDUCING THE DAMAGING CONSEQUENCES OF HEAD-ON COLLISIONS BETWEEN AUTOMOBILES WITH INCOMPATIBLE FORWARD ENERGY ABSORBING STRUCTURES ARE PRESENTED. VEHICLE AND OCCUPANT DYNAMIC RESPONSES OBTAINED IN TESTS OF AUTOMOBILES IMPACTING AT CLOSING SPEEDS IN EXCESS OF 85 MPH ARE PRESENTED AND ANALYZED. THE SERIES OF FOUR TESTS INCLUDED COLLISIONS BETWEEN STANDARD CARS AND BETWEEN STANDARD AND COMPACT CARS, INCLUDING ONE SMALL CAR WITH A MODIFIED BUMPER SYSTEM TO INCREASE ENERGY DISSIPATION CAPACITY OF THE FRONT STRUCTURE AND THEREBY REDUCE PASSENGER COMPARTMENT INTRUSION. EFFECTS OF THE WAVEFORM OF VEHICLE CRUSH PROPERTIES ON OCCUPANT INJURY POTENTIAL, AS DETERMINED FROM COMPUTER SIMULATION OF THE CRASH VICTIM, ARE DISCUSSED. FORMULATION OF A COMPUTER SIMULATION OF IMPACTS BETWEEN BUMPERS OF OPPOSING VEHICLES IS DESCRIBED, TOGETHER WITH RESULTS OF SIMULATED LOW-SPEED BUMPER UNDER/OVERRIDE COLLISIONS. /HSL/
