Title
(EN) DYNAMIC MOTION CONTROL SYSTEM USING MAGNETORHEOLOGICAL FLUID CLUTCH APPARATUSES
(FR) SYSTÈME DE COMMANDE DE MOUVEMENT DYNAMIQUE UTILISANT DES APPAREILS D'EMBRAYAGE À FLUIDE MAGNÉTORHÉOLOGIQUE
Abstract
(EN)
An active suspension system comprises at least one biasing device configured to support a body from a structure, and at least one motor. A magnetorheological (MR) fluid clutch apparatus(es) is coupled to the at least one motor to receive torque from the motor, the MR fluid clutch apparatus controllable to transmit a variable amount of torque. A mechanism is between the at least one MR fluid clutch apparatus and the body to convert the torque received from the at least one MR fluid clutch apparatus into a force on the body. Sensor(s) provide information indicative of a state of the body or structure. A controller receives the information indicative of the state of the body or structure and for outputting a signal to control the at least one MR fluid clutch apparatus in exerting a desired force on the body to control movement of the body according to a desired movement behavior.
(FR)
La présente invention concerne un système de suspension active qui comprend au moins un dispositif de sollicitation conçu pour supporter un corps d'une structure, et au moins un moteur. Un ou plusieurs appareils d'embrayage à fluide magnétorhéologique (MR) sont accouplés à un ou plusieurs moteurs pour recevoir le couple du moteur, l'appareil d'embrayage à fluide magnétorhéologique pouvant être commandé de sorte à transmettre une quantité variable de couple. Un mécanisme est agencé entre le ou les appareils d'embrayage à fluide magnétorhéologique et le corps pour convertir le couple reçu du ou des appareils d'embrayage à fluide magnétorhéologique en une force sur le corps. Un ou plusieurs capteurs fournissent des informations indiquant un état du corps ou de la structure. Un dispositif de commande reçoit les informations indiquant l'état du corps ou de la structure et est destiné à délivrer un signal pour commander le ou les appareils d'embrayage à fluide magnétorhéologique afin d'exercer une force souhaitée sur le corps en vue de commander le mouvement du corps en fonction d'un comportement de mouvement souhaité.
