Lateral Vibration of a Shinkansen and its Decreasing Measure
Hiroshi FUJIMOTO, Masayuki MIYAMOTO, Yoichi SHIMAMOTO
From the vibration data obrained 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 tlhe installed damper was tested up to 310 km/h in Shinkansen, and it was
verified.
