FINITE ELEMENT ANALYSIS FOR ESTIMATING THE EFFECT OF VARIOUS WORKING CONDITIONS ON THE TEMPERATURE GRADIENTS CREATED INSIDE A ROLLING TIRE

Periodic deformation of a tire during its rolling motion causes energy dissipating and heat generation due to hysteretic nature of the rubber. The increase in tire temperature may have disastrous effects on safe service life and safety of vehicles. In this study a numerical simulation based on finite element method is used for evaluating the effect of various working conditions on temperature field of a rolling tire. Compared with related published studies, the obtained results show a very good consistency and validity.
