STOPPING-DISTANCE ANALYSIS

A METHOD OF PLOTTING AND COMPARING THE THEORETICAL, REQUIRED, AND MEASURED STOPPING DISTANCE AS REQUIRED BY THE DEPARTMENT OF TRANSPORTATION (DOT) IS DISCUSSED. THE HIGH COEFFICIENT STOPPING DISTANCE REQUIREMENTS HAVE BEEN EXTRAPOLATED TO AMERICAN SOCIETY FOR TESTING AND MATERIALS SKID NUMBERS OVER A RANGE OF 50 TO 120. THIS WILL GIVE THE BRAKE SYSTEM DESIGNER MORE CONFIDENCE IN TEST RESULTS ON A KNOWN SKID NUMBER SURFACE. THE GRAPHICAL TECHNIQUE DEVELOPED, ENABLES THE BRAKE SYSTEM DESIGNER TO SYSTEMATICALLY COMPARE PREDICTED AND ACTUAL PERFORMANCE OF VARIOUS BRAKE SYSTEM DESIGNS ON A VARIETY OF TIRE-ROAD COEFFICIENTS WITH DOT REQUIREMENTS FOR THE SAME CONDITIONS. SAMPLE GRAPHS ARE SHOWN ALONG WITH THE INSTRUCTIONS FOR CARRYING OUT THE PROCEDURE. /NHTSA/
