Experimental Research of Tire Elastomer-Surface Tribological Properties

This paper presents a new experimental test rig and experimental findings on tire elastomer-surface friction characteristics that are necessary for modeling tire thermodynamic characteristics and then tire characteristics, including the μ-curve in the driving and braking modes of operation.Unlike common approaches, the paper offers experimental procedures and test results on both steady and non-steady friction process by introducing (i) velocity factor, (ii) normal pressure distribution, and (iii) a temperature factor in the elastomer-surface contact. The group of (i), (ii), and (iii)-listed factors, taken together, represents the key elements by means of which tribological properties of the tire-road interaction, i.e., an elastomer-surface friction pair, impact the μ-curve.Copyright
