DYNAMIC TESTS OF AN ENERGY ABSORBING BARRIER EMPLOYING STEEL DRUMS

THE RESULTS OF THREE FULL-SCALE VEHICLE IMPACT TESTS INTO AN ENERGY ABSORBING BARRIER EMPLOYING 55 GALLON TIGHT HEAD STEEL DRUMS ARE REPORTED. THE TESTS WERE CONDUCTED WITH 1968 SEDANS WEIGHING APPROXIMATELY 4,700 LBS. AND TRAVELING AT SPEEDS OF 54 TO 64 MPH. IMPACTS INTO THE TEST BARRIERS CONSISTED OF A HEAD-ON AND A 9 DEG. IMPACT INTO THE NOSE AND AN 11 DEG. IMPACT MIDWAY ALONG THE SIDE OF THE BARRIER. THE HEAD-ON AND ANGLE IMPACTS INTO THE NOSE OF THE BARRIER RESULTED IN VEHICLE PASSENGER COMPARTMENT DECELERATIONS LESS THAN 12 G'S. VEHICLE DAMAGE WAS MODERATE. THE VEHICLE REMAINED STABLE AND UPRIGHT DURING IMPACT. ALMOST ALL THE DRUMS IN THE BARRIER WERE CRUSHED TO SOME EXTENT. EXTENSIVE REPAIRS WOULD HAVE BEEN REQUIRED TO RESTORE THE BARRIER TO A FUNCTIONAL LIMIT. THE IMPACT INTO THE SIDE OF THE BARRIER DID NOT PRODUCE COMPLETELY SATISFACTORY RESULTS. THE VEHICLE WAS REDIRECTED, BUT BY THE BRIDGE APPROACH GUARDRAIL BEHIND THE BARRIER. THE RESULTS OF THESE 3 TESTS INDICATE THAT THE BARRIER'S EFFECTIVENESS IN REDUCING THE SEVERITY OF MOST IMPACTS IS SUCH THAT IT COULD BE USED OPERATIONALLY ON AN EXPERIMENTAL BASIS. DESCRIPTIONS OF THE ELECTRONIC AND PHOTOGRAPHIC DATA ACQUISITION SYSTEMS EMPLOYED ARE INCLUDED, AS ARE THE PROCEDURES USED TO ANALYZE THE DATE OBTAINED WITH THESE SYSTEMS. /AUTHOR/
