MODEL STUDY OF SINGLE-VEHICLE ACCIDENT WITH FIXED OBJECT

FULL-SCALE AUTOMOBILE COLLISION TESTS INTO DIXED OBJECTS ARE EXPENSIVE AND TIME CONSUMING, ESPECIALLY IF THE REPRODUCIBILITY OF THE TEST AND THE CONTROLLABILITY OF VARIOUS INFLUENCING PARAMETERS ARE QUESTIONED. THE INTENTION OF SCALE MODEL TESTS IS TO SUPPLEMENT, BUT NOT TO REPLACE, FULL-SCALE TESTS. IF THEY ARE USED PROPERLY, THE MODEL TESTS WILL ELIMINATE TRIVIAL FULL-SCALE EXPERIMENTS, GIVE AN INSIGHT TO THE PHENOMENON BY ASSEMBLING GOVERNING PARAMETERS, AND GUIDE TO THE EVENTUAL FORMULATION OF ANALYTICAL MODELS. THE DIMENSIONAL ANALYSIS WAS APPLIED TO COLLISION PHENOMENA OF AUTOMOBILES INTO FIXED OBJECTS, SUCH AS ROAD SIGNS, AND MODEL RULES WERE ESTABLISHED. A MODEL VEHICLE AND A MODEL SIGN WERE DESIGNED AND BUILT. TOTAL TEST SYSTEM WAS CHECKED OUT AND FOUND TO FUNCTION SATISFACTORILY. HIGH SPEED MOVING PICTURES WILL TAKEN TO ANALYZE THE MOTION OF THE MODEL. THE SPEED OF THE MOVING PICTURES MUST BE SCALED PROPERLY FROM THE CORRESPONDING FULL-SCALE COUNTERPART AS PERFORMED BY CALIFORNIA STATE HIGHWAY DIVISION FOR COMPARISON AND VALIDATION OF THE MODEL TESTS. /AUTHOR/
