Title:
VIBRATION CONTROL DEVICE FOR RAILWAY ROLLING STOCK
Document Type and Number:
Japanese Patent JPH06239232
Kind Code:
A
Abstract:

PURPOSE: To restrain excessive consumption of energy to drive the actuators of a vibration control device by inputting a speed signal to a controller, and controlling vibration only in a previously set speed range.

CONSTITUTION: Fluid actuators 4 acting in the right and left directions between a vehicle body 1 and bogies, and fluid actuator 5 acting in the vertical direction on both side positions of a vehicle, are provided. Lateral vibration acceleration and vertical vibration acceleration detected by means of lateral vibration accelerometers 2 and vertical vibration accelerometers 3, and actuator stroke and inner pressure detected by means of sensors provided on the actuators are inputted to a controller. The control output required for vibration control is obtained by computation, meanwhile a speed signal V from a speedmeter is inputted to the controller, it is compared with a previously set control lower limit speed Vc, and in the case of V>Vc, the actuators are driven so as to control vibration.
