Rubber-covering rolls are in wide use in many industrial machines for processing, pressing and conveying paper and plastic film. Recently, with high-load and high-speed, we experience the polygonal deformation caused by viscoelastical deformation of roll-covering rubber. It is said that the above mentioned phenomenon is influenced by rubber damping and its deformation recovery characteristics. From some experiments and calculations about rubber damping and its deformation recovery characteristics, following conclusions are obtained. That is to say, rubber damping coefficient has strain rate dependency and it influences nonlinearity of deformation recovery characteristics. This paper presents identification of them based some measurements and numerical simulations.
