In order to clarify the relation between train dynamics and track irregularity, test trains running on track irregularities artificially set were run at a speed of up to 210km/h and the responses of the carbody, etc., were observed on the Jyoetsu Shinkansen line in Japan. The authors analysed the responses of the carbody to alignment irregularity with gauge enlargement (enlargement of the rail-flange clearance) on the basis of the observed data. The responses were compared with the results of vehicle dynamics simulation. In addition, using the same simulation program, the influence of gauge variation on carbody hunting motion of a new high-speed Shinkansen train, which has soft suspension between the carbody and bogie owing to the bolsterless bogie, was studied. It was concluded that gauge enlargement decreases the response to alignment irregularity but lowers the stability of hunting characteristics.

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. The authors' 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 a train for the yawing mode are likely to emerge, and when aerodynamic forces work in a tunnel section. Referring to those results, by simulation analysis etc., it was found that two longitudinal dampers installed parallel between the car ends (Fig. 1) with their forces depending on the angular velocity between cars, are effective in decreasing the train vibration including the tail car's vibration. Then, the prototype of the longitudinal dampers between the cars for Shinkansen was designed by obtaining the proper damping coefficient through simulation. The effectiveness of the installed damper was verified when it was tested up to 310 km/h in the Shinkansen train.
