Abstract

L'invention concerne un système et un procédé à amortissement variable de type à rétroaction intelligente, applicables à un appareil d'amortissement. Le système d'amortissement comprend un moteur linéaire (1), un vérin (2) à action directe, un bloc (3) de soupapes de commande de course, un moteur pas à pas (6), un bloc (7) de soupapes de commande d'étranglement, un processeur d'acquisition (8), un dispositif de commande (9), un capteur de pression (10), un vérin (11) d'amortissement, un couvercle (13) de vérin d'amortissement, un capteur de vitesse (14) et un capteur de déplacement (16). Le réglage automatique de la capacité d'amortissement dans une large plage est mis en œuvre au moyen d'une commande en boucle fermée du capteur de vitesse (14) et du capteur de pression (10). Une extrémité du vérin (2) à action directe est reliée au moteur linéaire (1), et l'autre extrémité est reliée au bloc (3) de soupapes de commande de course. Le bloc (3) de soupapes de commande de course est relié au vérin (11) d'amortissement au moyen d'un tuyau. Une extrémité du vérin d'amortissement (11) est reliée au bloc (7) de soupapes de commande d'étranglement, et l'autre extrémité est reliée au couvercle (13) de vérin d'amortissement. Le capteur de vitesse (14) et le capteur de déplacement (16) sont reliés au couvercle (13) de vérin d'amortissement. Le dispositif de commande (9) et le capteur de pression (10) sont reliés au bloc (7) de soupapes de commande d'étranglement. Le moteur pas à pas (6), coaxial avec le vérin (11) d'amortissement, est relié au bloc (7) de soupapes de commande d'étranglement. Le système d'amortissement et le procédé d'amortissement peuvent amortir une charge d'impact incertaine, réduire efficacement le volume d'une source d'énergie et compenser une fuite d'huile hydraulique d'un amortisseur hydraulique.
