Title (EN) CABIN VIBRATION DAMPING SYSTEM FOR WORK VEHICLE
(FR) SYSTÈME D'AMORTISSEMENT DE VIBRATIONS D'HABITACLE POUR VÉHICULE DE TRAVAIL
(JA) 作業車両のキャビン制振システム
Abstract:
(EN) This cabin vibration damping system (100) comprises: a shock absorber (10) provided between the frame (2) and cabin (6) of a tractor (1) and able to freely change the damping force for damping the cabin (6) vibration; an acceleration sensor (62) for detecting at least the acceleration (α) of the cabin (6) in the vibration direction of the cabin (6); and a control device (60) for controlling the magnitude of the damping force to be generated by the shock absorber (10), on the basis of the acceleration (α) of the cabin (6) detected by the acceleration sensor (62) and resonance frequency (fm) of the cabin (6).
(FR) L'invention concerne un système d'amortissement de vibrations d'habitacle (100) comprenant : un amortisseur (10) disposé entre le châssis (2) et l'habitacle (6) d'un tracteur (1) et apte à modifier librement la force d'amortissement pour amortir les vibrations de l'habitacle (6) ; un capteur d'accélération (62) permettant de détecter au moins l'accélération (α) de l'habitacle (6) dans la direction de vibration de l'habitacle (6) ; et un dispositif de commande (60) permettant de commander l'amplitude de la force d'amortissement devant être générée par l'amortisseur (10), sur la base de l'accélération (α) de l'habitacle (6) détectée par le capteur d'accélération (62) et de la fréquence de résonance (fm) de l'habitacle (6).
(JA) キャビン制振システム(100)は、トラクタ1のフレーム(2)とキャビン(6)との間に設けられ、キャビン(6)の振動を減衰する減衰力を変更自在な緩衝部(10)と、少なくともキャビン(6)の振動方向におけるキャビン(6)の加速度(α)を検出する加速度センサ(62)と、加速度センサ(62)で検出されたキャビン(6)の加速度(α)及びキャビン(6)の共振周波数(fm)に基づいて、緩衝部(10)が生じる減衰力の大きさを制御する制御装置(60)と、を備える。
