<P>PROBLEM TO BE SOLVED: To provide a railway car vibration control device that can effectively suppress the car body vibration by providing stable thrust force. <P>SOLUTION: The railway car vibration control device 1 for suppressing vibration of the vehicle body B includes a cylinder 2, a piston 3 which is slidably inserted into the cylinder 2, a rod 4 which is inserted into the cylinder 2 to be linked to the piston 3, a rod-side chamber 5 and a piston-side chamber 6 which are partitioned by the piston 3 in the cylinder 2, a tank 7, a first open/close valve 9 which is provided midway along a first passage 8 that links the rod-side chamber 5 and the piston-side chamber 6, a second open/close valve 11 which is provided midway along a second passage 10 that links the piston-side chamber 6 and the tank 7, and actuators A1, A2 having a pump 12 for supplying a liquid to the rod-side chamber 5. The first open/close valve 9 and the second open/close valve 11 are opened and the pump 12 is driven in order to warm up the actuators A1, A2 after start-up and before the device switches to normal control mode for suppressing vibration of the vehicle body. <P>COPYRIGHT: (C)2013,JPO&INPIT |
