Thermomechanical Analysis Strategies for Elastomer Components Under Dynamic Loading
In the form of bearings, seals, conveyors, V-belts and pneumatic tires, elastomers are commonly used to transmit or handle time-dependent (dynamic) loadings. Dissipative effects in cyclically loaded elastomer components lead to a steady loss of mechanical input energy. The transformation of mechanical energy to thermal energy results in an increase of the temperature of the elastomer component. In this contribution, finite element (FE) solution schemes for the computation of the displacement and temperature field are discussed. First, a simultaneous solution scheme is used to analyse a cyclically loaded elastomer specimen (strong coupling of the displacement and temperature field). Second, a sequentially coupled solution scheme (weak coupling of the displacement and temperature field) is presented for the modelling of steady state dynamic systems. Subsequently, the sequential analysis is used to predict the thermo-mechanical behaviour of steady state rolling tires.
