RAILWAY VEHICLE DAMPING DEVICE
First Claim
1. A damping device for a railway vehicle, comprising:
- at least two front side vibration suppression force generating sources interposed between a front bogie and a vehicle body of the railway vehicle;
at least two rear side vibration suppression force generating sources interposed between a rear bogie and the vehicle body of the railway vehicle; and
a programmable controller programmed to;
determine a yaw suppression force for suppressing vibration in a yaw direction of the vehicle body;
cause the front side vibration suppression force generating sources and the rear side vibration suppression force generating sources to output the yaw suppression force; and
when the railway vehicle travels in a curve section, cause at least a part of the front side vibration suppression force generating sources and at least a part of the rear side vibration suppression force generating sources to output the yaw suppression force while causing all of remaining front side vibration suppression force generating sources and all of remaining rear side vibration suppression force generating sources to function as passive dampers.

Abstract
A railway vehicle damping device comprises at least two front side actuators interposed between a front bogie and a vehicle body of a railway vehicle, and at least two rear side actuators interposed between a rear bogie and the vehicle body of the railway vehicle, and suppresses vibration in a yaw direction of the vehicle body using a yaw suppression force generated by the actuators. After determining that the railway vehicle is traveling in a curve section, a control device causes at least one of the front side actuators and at least one of the rear side actuators to generate a yaw suppression force, and causes all of the remaining actuators to function as passive dampers. As a result, passenger comfort in the railway vehicle during travel in the curve section is improved.
