Title:
VIBRATION CONTROL DEVICE FOR ROLLING STOCK
Document Type and Number:
WIPO Patent Application WO/2019/065434
Kind Code:
A1
Abstract:
This control device is configured including a damper control device, which variably controls damping force generated by 1-axle through 4-axle dampers, and an anomaly detection estimation unit, which detects and estimates anomalies in the 1-axle through 4-axle dampers. The anomaly detection estimation unit is provided with a roll data calculation unit (roll data output device), which outputs roll data that changes depending on the roll (leftward and rightward rocking) of a body, and a breakdown assessment device 14, which compares the roll data outputted from the roll data calculation unit with a breakdown assessment value in a prescribed travel condition and assesses whether or not the 1-axle through 4-axle dampers 7A-7D have broken down.
