TY - JOUR PY - 1971// TI - Friction and the mechanics of skidding automobiles JO - Highway research record A1 - Brach, Raymond Matthew SP - 99 EP - 106 VL - 37 IS - N2 - This paper demonstrates that a rather general mathematical model of a skidding automobile can be constructed and solved with little difficulty. The solution can be used in curve-fitting of data from stopping distance experiments and in obtaining speeds where skid distance and friction characteristics are known. Skid marks from accident studies are used as an example. The importance of drag forces is discussed, and a way of obtaining instantaneous friction coefficient measurements from stopping distances is given. It is suggested that the substitution of instantaneous friction coefficient measurements, obtained from skid trailer runs, into stopping distances formulas is responsible for the calculated distance exceeding actual measurements 90% of the time.
