Abstract
(EN)
An actuator is provided between a vehicle body and a bogie. A damper is provided between the bogie and each wheel. The bogie is provided with a bogie-side acceleration sensor. The vehicle body is provided with a vehicle body-side acceleration sensor. A control device causes the bogie to vibrate by causing the actuator to vibrate at a prescribed frequency, to determine an abnormality of the damper or the sensor.
(FR)
Un actionneur est disposé entre une carrosserie de véhicule et un bogie. Un amortisseur est disposé entre le bogie et chaque roue. Le bogie est pourvu d'un capteur d'accélération côté bogie. La carrosserie de véhicule est pourvue d'un capteur d'accélération côté carrosserie de véhicule. Un dispositif de commande amène le bogie à vibrer en amenant l'actionneur à vibrer à une fréquence prescrite, pour déterminer une anomalie de l'amortisseur ou du capteur.
(JA)
車体と台車との間には、アクチュエータが設けられている。台車と各車輪との間には、ダンパが設けられている。台車には、台車側加速度センサが設けられている。車体には、車体側加速度センサが設けられている。制御装置は、アクチュエータを所定の周波数で加振させることによって台車を加振させ、ダンパまたはセンサの異常を判定する。
