A THREE DIMENSIONAL COMPUTER SIMULATION OF A MOTOR VEHICLE CRASH VICTIM. PHASE I: DEVELOPMENT OF THE COMPUTER PROGRAM

A DIGITAL COMPUTER PROGRAM TO SIMULATE A MOTOR VEHICLE CRASH VICTIM, EITHER OCCUPANT OR PEDESTRIAN, IN THREE DIMENSIONS IS CURRENTLY UNDER DEVELOPMENT. THE DYNAMICS MODEL OF FORTY-DEGREES-OF-FREEDOM CONSISTS OF FIFTEEN RIGID BODY SEGMENTS CONNECTED BY BALL-AND-SOCKET AND PINNED JOINTS, AND INCLUDES SPRING AND DISSIPATIVE TORQUES AT THE JOINTS TO SIMULATE MUSCLE TONE. PROVISION IS MADE WITHIN THE FORMULATION TO ALTER THE NUMBER OF SEGMENTS AND JOINTS OF THE MODEL. A CONTACT MODEL WAS DEVELOPED TO SIMULATE EXTERNAL FORCES ACTING ON THE CRASH VICTIM, INCLUDING FORCES CAUSED BY CONTACT WITH VEHICLE SURFACES, BETWEEN BODY SEGMENTS, AND RESTRAINT FORCES FROM BOTH BELT AND INFLATABLE TYPES OF RESTRAINT SYSTEMS. A GRAPHICS DISPLAY MODEL PRODUCES ORTHOGONAL VIEWS OF THE VICTIM FROM BOTH AN OFF-LINE PLOTTER GRAPHICS ROUTINE AND A SIMPLIFIED PRINTER GRAPHICS DISPLAY, DEVELOPED AS A DIAGNOSTIC TOOL. AN INJURY CRITERIA MODEL WAS DEVELOPED TO PROVIDE A MEANS FOR READILY ASSESSING THE DEGREE OF INJURY SUSTAINED BY THE SIMULATED CRASH VICTIM. /AUTHOR/
