EVALUATION OF LOADED ROLLING TYRE THERMAL FIELDS USING A FAST SCANNING INFRARED LINE CAMERA

Infrared thermography is a well-established technique for evaluating material properties and products quality through contact-less and non-descructive thermal measurements. The paper presents the investigation results of a loaded rolling tire-casing external surface temperature distribution via a fast scanning infrared line camera for industrial temperature measurements. An efficiency approach is developed to an automated image processing of the large digital thermograms set. An analytical model of a maximum external tire-casing surface temperature time history during its rotation is identified and its parameters are estimated with very high reliability.
