Lateral Vibration and Decreasing Measure of it on a Shinkansen Train (Decrease of Train Vibration with Yaw Damper between Cars)

摘要

From the vibration data obtained simultaneously on several cars in the same Shinkansen train, it was observed that the vibration amplitude of the tail car is greater than those of the other cars in a train (Fig.1). 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 carbody hunting characteristics of the train for the yawing mode are likely to emerge, and when aerodynamic forces work in tunnel section. Referring to these results, it was found by simulation analysis, etc. that two car end yaw dampers longitudinally and parallel installed between car ends (Fig. 2) in proportion to the angular velocity, are effective to decrease the train vibration including the tail car's vibration.
