GENERIC DATA FOR REPRESENTING TRUCK TIRE CHARACTERISTICS IN SIMULATIONS OF BRAKING AND BRAKING-IN-A-TURN MANEUVERS

The generic data presented in this report are intended for use in studying the performance of trucks (including articulated vehicles) in braking and braking-in-a-turn maneuvers, such as those included in recent versions of Federal Motor Safety Standard (FMVSS) 121. These data are based on a semiempirical tire model that uses simplified theoretical concepts in conjunction with measured or specified tire stiffness and tire-road frictional qualities. These data are not measured directly; rather they are computed using measured and specified tire properties. The main body of this report provides a users manual for spread sheet calculations that compute longitudinal and lateral tire forces as functions of vertical load, velocity, longitudinal slip, and slip angle. The results of these calculations are tables of data containing values of tire forces that are suitable for use in computer simulations of heavy trucks.
