AUTOMOBILE-BARRIER IMPACT STUDIES USING SCALE-MODEL VEHICLES

GEOMETRIC PROPERTIES OF RIGID CONCRETE MEDIAN BARRIERS AND TRAJECTORY PARAMETERS OF A CLASS OF IMPACTING AUTOMOBILES WERE TO BE CORRELATED WITH RESULTING TRAJECTORY AND VEHICLE ATTITUDE PARAMETERS AFTER VEHICLE-BARRIER IMPACT. CORRELATIONS WERE TO BE PERFORMED BY ANALYSIS OF HIGH-SPEED MOVIES OF AN AUTOMOBILE-BARRIER IMPACT SIMULATION DONE BY 1/8-SCALE MODEL VEHICLES AND BARRIERS. MAJOR CHANGES IN VEHICLE ATTITUDE WERE FOUND TO BE CAUSED BY RELATIVELY MINOR BARRIER DESIGN CHANGES. OBJECTIVES WERE NOT FULLY ACCOMPLISHED DUE TO LACK OF DATA NEEDED FOR VEHICLE AND BARRIER SCALING. MODELING TECHNIQUES WERE ADVANCED TO THE POINT THAT, WHEN VALIDATION DATA BECOME AVAILABLE, SCALE MODELS CAN BE USED TO STUDY THE EFFICACY OF BOTH RIGID AND YIELDING BARRIERS.
