Title:
ROLLING STOCK BODY BENDING VIBRATION DAMPING DEVICE
Document Type and Number:
Japanese Patent JP3309802
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To ensure constant comfortableness even in the case of active bending vibration control being out of function by connecting a body and a vibration damping device in parallel by an elastic support member and a rigid body support member, and making the connection of the rigid body support member releasable.
SOLUTION: An actuator 4 is disposed at the underfloor of almost the center part of a body 1 and connected to an active mass 5. A sensor 6 fixed to the floor face of the body 1 detects the vertical vibration of the body 1. A controller 7 actuates the actuator 4 on the basis of the detected quantity of the sensor 6 to generate inertia force of the active mass 5 so as to reduce the bending vibration of the body 1. Rigid body support mechanism 8 connects the body 1 and the actuator 4, supports the weight of a control device, transmits inertia reaction of the active mass 5 to the body 1 and releases connection if necessary. An elastic support body 9 connects the body 1 and the actuator 4 in parallel with the rigid support mechanism 8. An action command device 10 outputs connection release and reconnection signals of the rigid body support mechanism 8 by signals from the controller 7.
