Abstract

Procédé de détermination de la valeur de la raideur de la fixation du support d'un dispositif d'amortissement pendulaire à un composant de groupe motopropulseur de véhicule, ce dispositif d'amortissement pendulaire visant à amortir une oscillation de torsion se propageant dans le groupe motopropulseur, et comprenant au moins un corps pendulaire mobile par rapport au support, ce dispositif d'amortissement pendulaire étant associé à un moment d'inertie dynamique égal au rapport entre le couple associé à l'oscillation de torsion appliqué sur le dispositif d'amortissement pendulaire et la dérivée seconde temporelle de l'angle de rotation autour de l'axe de rotation du composant d'un point du support du dispositif d'amortissement pendulaire par rapport à sa position de repos, procédé dans lequel: - on détermine une valeur absolue prédéfinie pour le produit : - de la valeur du couple transmis à travers la fixation du support du dispositif d'amortissement pendulaire au composant lorsqu'une oscillation de torsion est appliquée sur le dispositif d'amortissement pendulaire, et - de la valeur de ce moment d'inertie dynamique, et - on détermine la valeur de cette raideur de manière à ce que la valeur absolue dudit produit soit inférieure à la valeur absolue prédéfinie.A method of determining the value of the stiffness of the attachment of the bracket of a pendulum damping device to a vehicle powertrain component, the pendulum damping device for damping a torsional oscillation propagating in the powertrain , and comprising at least one pendular body movable relative to the support, this pendular damping device being associated with a dynamic moment of inertia equal to the ratio between the torque associated with the torsional oscillation applied to the pendular damping device and the second time derivative of the angle of rotation around the axis of rotation of the component of a point on the support of the pendulum damping device with respect to its rest position, method in which: - an absolute value is determined predefined for the product: - the value of the torque transmitted through the attachment of the support of the pendulum damping device to the component when a bone torsional oscillation is applied to the pendulum damping device, and - the value of this dynamic moment of inertia, and - the value of this stiffness is determined so that the absolute value of said product is less than the value predefined absolute.
