MÉTHODE DE TEST DE LA RÉSISTANCE À UNE PERTE DE PRESSION D'UN PNEUMATIQUE
摘要:
The invention relates to a method for testing the resistance of a tire to pressure loss after a perforation, characterized in that it comprises the following steps: creating, in the wall of the tire, a plurality of perforations by inserting a plurality of perforating objects through said wall; rolling the tire comprising the perforating objects over a given distance with a controlled inflation pressure; stopping the rolling; and determining, for each perforation, an index of resistance to pressure loss on the basis of an estimation of the leakage rate of the perforation.
