ANALYSIS OF TIRE DEFORMATION IN OPERATION FROM THE DATA OF TEMPERATURE RISE

Knowledge of the deformation amplitude of the tire components during the actual running is important in the analysis of the fatigue process of the tire components. Attempts to imbed strain gages in the tire carcass to measure the deformation met difficulties due to the alteration of carcass properties in the process of imbedding the strain gages. The tire deformation in operation from the data of temperature rise is estimated. Measurement of the temperature rise is considerably easier than the measurement of the deformation. The temperature data are analyzed by considering the dynamics of self-heating which includes the heat generation rate terms. Examples of the analysis are illustrated. The deformation determined by this procedure shows consistent correlations with the load, speed and carcass modulus.
