Filed: 1998-08-31
Abstract: PROBLEM TO BE SOLVED: To provide an oscillation control device for a railway rolling stock in which a damper can generate a damping force having a suitable value even though vertical and lateral oscillation is applied to a vehicle body. SOLUTION: This oscillation control device for railway rolling stock has a lateral displacement sensor 17 for detecting a lateral displacement of a vehicle body 4, and a damping force correcting part (correcting means) for correcting a control signal B in accordance with a detection signal from the sensor 17. When a railway rolling stock 1 runs on a curved path, the vehicle body 4 vertically oscillates, and accordingly, vertical and lateral forces are applied to the vehicle body 4. Even though the damper is tilted, a lateral displacement of the vehicle body 4 is detected by the lateral displacement sensor 17, and a tilting angle of the damper is calculated on the basis of the detected signal. Then, a correction signal is calculated from the tilting angle of the damper 5, and a control signal is corrected in accordance with the correction signal. Thus, corrected control signal is delivered to a damping force control part. Accordingly, the damper 5 can generate a damping force in accordance with a tilting angle of the damper 5, thereby the damper 5 can generate a daming force having an appropriate degree even though vertical and lateral oscillation is applied to the vehicle body 4.
