Relationship between Frictional Variations and Tire Characteristics

-An improvement to Brush model using the Transient Characteristics-

Abstract

This paper explores the relationship between the oscillatory variations of the frictional forces developed in braked tires and the several kinds of tire characteristics obtained from experiments. Among others, the transfer function of tires when excited in fore-aft direction is then highlighted, and the fundamental role of the tread rubber is investigated in terms of the transient properties by the aid of the so-called brush model
