Generic Data for Representing Truck Tire Characteristics in Simulations of aBraking and Braking-in-a-Turn Maneuvers

摘要

The generic data presented in this report are intended for use in studying theperformance 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. 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.
