FEASIBILITY STUDY OF TRAILER TECHNIQUES FOR TIRE TRACTION. VOLUME I. SUMMARY

The report presents the results of a nine-month test using a two-wheeled towed traction trailer. The purpose of the test was to evaluate the existing methodology for determining the relative braking traction characteristics of a production test tire and an ASTM tire. The test, specified by the National Highway Traffic Safety Administration (NHTSA), included segments designed to (1) determine the repeatability of the test procedure and apparatus and to (2) evaluate the effect of certain dependent variables: tire load, tire inflation pressure, road speed, road surface coefficient of friction, and surface water depth. Statistical techniques are employed to analyze the data with respect to the test reliability. The influence of the varied test parameters is demonstrated by the data tabulations and appropriate graphs. Some specific details of the apparatus and technique are examined and discussed with regard to refining the two-wheeled trailer traction measurement.
