UNDERRIDE/OVERRIDE OF AUTOMOBILE FRONT STRUCTURES IN INTERVEHICULAR COLLISIONS - VOLUME 1: HEAVY VEHICLE REAR UNDERRIDE

ANALYTICAL AND EXPERIMENTAL RESULTS OBTAINED IN A STUDY OF THE REQUIREMENTS AND PERFORMANCE OF REAR UNDERRIDE GUARDS FOR HEAVY VEHICLES ARE PRESENTED IN THIS REPORT. A TOTAL OF TWELVE FULL-SCALE TESTS WERE CONDUCTED IN TWO PHASES OF THE EXPERIMENTAL PROGRAM. RESULTS OF THE FIRST PHASE, CONSISTING OF SIX TESTS USING A RIGID SIMULATED UNDERRIDE GUARD MOUNTED ON AN SAE BARRIER, ARE REPORTED IN REFERENCE 1. THE SECOND SERIES OF SIX FULL-SCALE TESTS, REPORTED HEREIN, WERE PERFORMED USING PROTOTYPE UNDERRIDE GUARD DESIGNS MOUNTED ON THE REAR OF SEMI-TRAILER TRUCKS. THE EFFECTS OF IMPACTING VEHICLE SIZE AND WEIGHT, IMPACT VELOCITY, RIGID AND YIELDING UNDERRIDE GUARDS, AND UNDERRIDE GUARD GROUND CLEARANCE HEIGHT ARE AMONG THE PARAMETERS INVESTIGATED. /NTIS/
