From the vibration data obtained simultaneously on several cars in the same Shinkansen train, it was discovered that the vibration amplitude of the tail car is greater than that of the other cars in a train. Our analysis arrived at the conclusion that the vibration mode of a train has a tendency for the tail car to vibrate more than the others when the car body hunting characteristics of a train for the yawing mode are likely to emerge. Referring to those results, by simulation analysis etc., it was found that installation of the car end yaw damper in proportion to the angular velocity between cars was effective for decrease of the tail car's vibration. The effect of the installed damper was tested up to 275 km/h in Shinkansen, and it was verified.
