NUMERICAL AND EXPERIMENTAL INVESTIGATIONS FOR THE DESIGN OF ELASTOMERCOATED ROLLS

Elastomer coated roils play an important role in various technical bra nches. The high stresses in the elastomeric layer and their partial fa ilure lead not only to insufficient quality of She production process, but can also frequently destroy the whole rolling system completely T his article describes the mechanical behaviour of a two-roll system. N umerical and experimental methods are utilized in order to establish a n engineering approach for the design of such systems. The various sta ges of a design procedure will be presented which allows to determine the pa rameters important for the performance of this system, e. g. ni p width or nip pressure, taking into account the geometrical and physi cal nonlinearities of the material behaviour The design procedure is e xplained using the example of a specific roll pairing. The numerical a nd analytical results are verified by experiments.
