Abstract

Un procédé permet d’analyser un élément de carrosserie d’un véhicule et comprend : - une première étape (10-30) dans laquelle on fait vibrer l’élément à différentes fréquences et on détermine des déformations de zones de cet élément en fonction de ces fréquences, - une deuxième étape (40-50) dans laquelle on détermine parmi ces zones chaque zone présentant une déformation maximale et la fréquence associée, et - une troisième étape (60) dans laquelle on détermine, pour chaque zone de déformation maximale déterminée et en fonction d’au moins sa déformation maximale et la fréquence associée, un amortisseur de vibrations destiné à réduire cette déformation maximale une fois solidarisé fixement à une face interne de l’élément dans cette zone. Figure à publier avec l’abrégé : Fig. 2A method makes it possible to analyze a bodywork element of a vehicle and comprises: - a first step (10-30) in which the element is vibrated at different frequencies and the deformations of zones of this element are determined as a function of these frequencies, - a second step (40-50) in which one determines among these zones each zone having a maximum deformation and the associated frequency, and - a third step (60) in which one determines, for each zone of maximum deformation determined and as a function of at least its maximum deformation and the associated frequency, a vibration damper intended to reduce this maximum deformation once secured fixedly to an internal face of the element in this zone. Figure to be published with abstract: Fig. 2
