Title (EN) RAILROAD CAR VIBRATION DAMPING DEVICE
(FR) DISPOSITIF D'AMORTISSEMENT DE VIBRATIONS DE WAGON DE CHEMIN DE FER
(JA) 鉄道車両用制振装置
Abstract:
(EN) This railroad car vibration damping device (V1) comprises: an actuator (A) which can be expanded and contracted by hydraulic fluid supplied from a pump (12) that is driven by a motor (15); and a controller (C1) which has an estimation unit (42) for estimating the thrust of the actuator (A) from the current of the motor (15), and which feeds back the estimation thrust (Fm) estimated by the estimation unit (42) and controls the actuator (A).
(FR) L'invention concerne un dispositif d'amortissement de vibrations de wagon de chemin de fer (V1) qui comprend : un actionneur (A) qui peut être déployé et contracté par un fluide hydraulique fourni par une pompe (12) qui est entraînée par un moteur (15); et un dispositif de commande (C1) qui a une unité d'estimation (42) pour estimer la poussée de l'actionneur (A) à partir du courant du moteur (15), et qui renvoie la poussée d'estimation (Fm) estimée par l'unité d'estimation (42) et commande l'actionneur (A).
(JA) 本発明の鉄道車両用制振装置(V1)は、モータ(15)で駆動されるポンプ(12)からの作動液体の供給により伸縮可能なアクチュエータ(A)と、モータ(15)の電流からアクチュエータ(A)の推力を推定する推定部(42)を有して、推定部(42)が推定した推定推力(Fm)をフィードバックしてアクチュエータ(A)を制御するコントローラ(C1)とを備えている。
