Title (EN) VISCO-ELASTIC DAMPING ELEMENT BASED ON VISCO-ELASTIC MATERIALS
(FR) CORPS D'AMORTISSEMENT VISCOÉLASTIQUE À BASE DE MATÉRIAUX VISCOÉLASTIQUES
(DE) VISKO-ELASTISCHER DÄMPFUNGSKÖRPER AUF BASIS VISKOELASTISCHER MATERIALIEN
Abstract:
(EN) The invention relates to a method for producing a visco-elastic damping element comprising at least one visco-elastic spring element, characterized in that the visco-elastic spring element is structured from at least one visco-elastic material having a tan δ of at least 0.5, determined according to DIN 53535: 1982-03, and produced by means of a 3D printing method. The invention further relates to a visco-elastic damping element, which is produced or can be produced according to said method, and to a solid body comprising or consisting of a plurality of damping elements.
(FR) L'invention concerne un procédé de fabrication d'un corps d'amortissement viscoélastique comprenant au moins un élément ressort viscoélastique. L'invention est caractérisée en ce que l'élément ressort viscoélastique est constitué d'au moins un matériau viscoélastique présentant un tan δ d'au moins 0,5, déterminé selon la norme DIN 53535: 1982-03, et peut être produit par un procédé d'impression 3D. L'invention concerne en outre un corps d'amortissement viscoélastique, qui est fabriqué ou peut être fabriqué selon ce procédé, ainsi qu'un corps volumique, comprenant ou constitué d'une pluralité de corps d'amortissement de ce type.
(DE) Die Erfindung betrifft ein Verfahren zur Herstellung eines visko-elastischen Dämpfungskörpers umfassend mindestens ein viskoelastisches Federelement, dadurch gekennzeichnet, dass das viskoelastische Federelement aus mindestens einem viskoelastischen Material mit einem tan δ von wenigstens 0,5, bestimmt nach DIN 53535: 1982-03, aufgebaut ist und über ein 3D-Druckverfahren erzeugt wird. Die Erfindung betrifft zudem einen Visko-elastischer Dämpfungskörper, der nach diesem Verfahren hergestellt oder herstellbar ist sowie einen Volumenkörper, umfassend oder bestehend aus einer Vielzahl von derartigen Dämpfungskörpern.
