BRAKE APPLICATIONS - VALIDATION OF A COMPUTER SIMULATION

THE BRAKING ASPECTS OF THE HIGHWAY-VEHICLE-OBJECT SIMULATION MODEL (HVOSM) ARE VALIDATED BY MEANS OF FULL-SCALE VEHICLE EXPERIMENTS. EXCELLENT CORRELATION IS ACHIEVED IN THE DETAILS OF THE VEHICLE RESPONSE TO BOTH STRAIGHT AHEAD BRAKING AND COMBINED CORNERING- BRAKING MANEUVERS. THREE REPEAT RUNS OF EACH BRAKING MANEUVER WERE MADE AND ARE PRESENTED TO ESTABLISH THE REPEATABILITY OF THE EXPERIMENTAL RESULTS. THE REPEATABILITY WAS FOUND TO BE VERY GOOD. THE HVOSM WAS USED TO PREDICT THE VEHICLE RESPONSES DURING EACH BRAKING MANEUVER AND THESE ARE COMPARED WITH THE CORRESPONDING MEASURED RESPONSES. THE DETAILS OF THE CORRELATION ARE INDICATED AND DISCUSSED. THE CORRELATION IS FOUND TO BE EXCELLENT. THIS MEASUREMENT OF VEHICLE PARAMETERS, THE INSTRUMENTATION INSTALLED IN THE VEHICLE, AND TEST PROCEDURES ARE DESCRIBBED IN DETAIL. A QUALITATIVE ASSESSMENT OF THE SENSITIVITY OF THE COMPUTED VEHICLE RESPONSES TO A FEW OF THE INPUT PARAMETERS WAS MADE AND IS PRESENTED AND DISCUSSED. /AUTHOR/
