A THEORY OF ROLLING TYRE CHARACTERISTICS OF DRY AND WET ROADS

It is a well established fact that the dynamic behaviour of road vehicles in the plane of primary motion is sensitive to variations in contact forces generated by tyres on dry and specially on wet roads. In this paper we will present a general formulation of an analysis of rolling tyre characteristics based upon the Green's function approach. In any such attempt to quantify tyre characteristics, one is confronted with two formidable complementary problems. The first one is to obtain an adequately accurate model of the elastic structural response of the tyre; the second is that of modelling the elusive frictional behaviour, of both dry and wet roads. In the sequel we will mainly focus our attention on the former aspect and consider the latter in a simplified manner, mainly to illustrate its influence on the accuracy demanded of structural modelling and consequently on the tyre characteristics. A major objective of the present work is to evaluate the applicability of the Green's function approach as a practical design tool to discern the effects of tyre design features and operating variables. This is justified in view of the several simplifying assumptions which are introduced to make the problem tractable.
