REAR END STRUCTURAL CRASHWORTHINESS OF UNITIZED CONSTRUCTION VEHICLES, DESIGN DEVELOPMENT AND DESIGN VERIFICATION

THE OBJECT OF THE PROGRAM IS TO DEVELOP A REAR END STRUCTURE WITH IMPROVED CRASH ENERGY CONTROL CHARACTERISTICS FOR LATE-MODEL UNITIZED CONSTRUCTION AMERICAN-BUILT AUTOMOBILES. THE DESIGN EFFORT UTILIZED INFORMATION OBTAINED FROM FULL-SCALE BASELINE TESTS AND SCALE MODEL TESTS TO GENERATE VEHICLE MODIFICATIONS INTENDED TO MEET THE PROGRAM DESIGN GOALS. TWO ENERGY-ABSORBING CONCEPTS, POLYURETHANE FOAM AND STIFFENED SHEET METAL, WERE INTEGRATED INTO CRASHWORTHY REAR END DESIGNS. TWO DEVELOPMENT TESTS OF EACH DESIGN WERE PERFORMED. THE FOAM MODIFICATION WAS EVENTUALLY SELECTED FOR THE ANGLE BARRIER AND VEHICLE-TO-VEHICLE VERIFICATION TESTING. SEVERAL DESIGNS OF INFLATABLE HEAD RESTRAINTS DEVELOPED WERE ALSO TESTED IN THE PROGRAM. /NTIS/
