Title (EN) AN EQUIPMENT AND A METHOD FOR TESTING BODIES
(FR) EQUIPEMENT ET PROCEDE D'ANALYSE DE CORPS
Abstract:
(EN) The present invention concerns an equipment and a method for testing bodies made of a material which expediently has a uniform structure. The present invention may advantageously be used to test carbon electrodes which are to be used in an electrolysis process and is based on mapping the natural frequencies and damping factors (modal parameters) of the electrode. These parameters are used to provide information on whether the electrode has global or local defects, for instance cracks or density gradients.
(FR) L'invention concerne un équipement et un procédé permettant d'analyser des corps produits à partir d'un matériau qui, opportunément, présente une structure uniforme. Selon l'invention, on peut avantageusement analyser des électrodes au carbone utilisées dans une électrolyse en s'appuyant sur l'application des fréquences naturelles et les facteurs d'amortissement (paramètres modaux) des électrodes. Ces paramètres servent à fournir des informations permettant de savoir si les électrodes ont des défauts globaux ou locaux, tels que fissures ou gradients de densité.
