HEAT EXCHANGE WITH AIR AND TEMPERATURE PROFILE OF A MOVING OVERSIZE TIRE

A one-dimensional mathematical model of heat transfer in a tire with account for the deformation energy dissipation and heat exchange of a moving tire with air has been developed. The mean temperature profi les are calculated and transition to a stationary thermal regime is considered. The infl uence of the rate of energy dissipation and of effective thermal conductivity of rubber on the temperature fi eld is investigated quantitatively.
