Investigating Temperature Effects on Mechanical Behavior of Rubber Compounds Embedded in Composite Structure of Pneumatic Tires

Owing to elastic and viscous characteristics of embedded rubber compounds, some of the supplied mechanical energy to composite structure of a rolling tire is dissipated as heat. as a result, the tire may have different body temperatures for different operating conditions. in most performed studies, just temperature distribution is investigated and the mechanical behaviour of tire structure, which is highly temperature-dependent, is ignored. in this study a 3d finite element model is developed for evaluating the effects of loading conditions and the body temperature on mechanical behaviour of the tire. the obtained results are compared with related published works to evaluate the accuracy of the analysis.
