Investigating the effect of temperature on mechanical behavior of rubber compounds embedded in composite structure of pneumatic tires

Abstract

Owing to elastic and viscous characteristics embedded rubber compounds, the dissipated energy from periodic deformation is converted into heat generation and consequently, the tire may have different body temperatures for different operating conditions. In most performed investigations, just temperature distribution is considered and the mechanical behaviour of rubber parts which are highly temperature-dependent is ignored. In this study a 3D finite element model is used for evaluating the effects of loading conditions and rubber temperature on mechanical behaviour of tire. Comparing with related published works, the results of presented study have a great accuracy and can provide a comprehensive analysis to avoid the temperature related failure.
