Résumé

In this study, we develop the radiative energy transfer method for pre-stressed orthotropic plate vibra-tional on visco-elastic foundation. For orthotropic plate system, the formula of the energy transfer depends not only on the distance between the observation point and source point, but also on the head angle of the wave. And the in-plane pre-stresses and visco-elastic foundation applied on the orthotropic plate can change the wave number, group velocity and input power. Some numerical simulations are performed for a typical tyre model to verify its validation. The simulation results, such as energy density distribution and energy flow field, are compared with the traditional modal superposi-tion solutions for various frequencies and damping loss factors. We analyze the influence of elastic stiffness and pre-stresses on the dynamic response of the orthotropic plate by the proposed model.
