Title (EN) METHOD AND APPARATUS FOR MEASURING AND LOGGING THE PERFORMANCE OF A VEHICLE SUSPENSION SYSTEM
(FR) PROCÉDÉ ET APPAREIL DE MESURE ET D'ENREGISTREMENT DE LA PERFORMANCE D'UN SYSTÈME DE SUSPENSION DE VÉHICULE
Abstract:
(EN) A method for measuring and logging the performance of a wheeled vehicle suspension system by measuring the dynamic performance of at least one component of said vehicle suspension system, the method including the steps of: setting the vehicle on a pre-determined path and within a pre-determined speed range; causing the suspension of said vehicle to be displaced by a substantially predetermined amount by causing the wheels of the vehicle to roll over one or more objects of known size on said path; measuring the displacement of said at least one suspension system component relative to the sprung mass of the vehicle and/or one or more fixed objects in response to said displacement; measuring the oscillation frequency of said at least one vehicle suspension system component in response to said displacement; and determining the suspension damping characteristics relating to the at least one vehicle suspension system component using the displacement and frequency measurements.
(FR) L'invention concerne un procédé de mesure et d'enregistrement de la performance d'un système de suspension de véhicule à roues par mesure de la performance dynamique d'au moins un composant dudit système de suspension de véhicule, le procédé comprenant les étapes consistant à : paramétrer le véhicule sur un trajet prédéfini et à l'intérieur d'une plage de vitesse prédéfinie ; amener la suspension dudit véhicule à se déplacer d'une quantité sensiblement prédéfinie en amenant les roues du véhicule à rouler sur un ou plusieurs objets de taille connue se trouvant sur ledit trajet ; mesurer le déplacement dudit composant de système de suspension par rapport à la masse suspendue du véhicule et/ou à un ou plusieurs objets fixes en réponse audit déplacement ; mesurer la fréquence d'oscillation dudit composant de système de suspension de véhicule en réponse audit déplacement ; et déterminer les caractéristiques d'amortissement de suspension par rapport audit composant de système de suspension de véhicule à l'aide des mesures de déplacement et de fréquence.
