To reduce the running vibration of Shinkansen train, especially in tunnel sections, a potential of inter-vehicle lateral dampers installed between car-bodies is examined. Here, it has been regarded to be difficult to improve the ride quality in both open and tunnel sections only with lateral dampers or anti-rolling devices between car-body and truck. An equivalent single-car model, that represents an intermediate car in infinite-length train, is utilized to examine the effect of the inter-vehicle lateral damper and specify its damping coefficient. Then, a practical train model composed of eight cars is used to verify the tendency analyzed by the equivalent single-car model. As a result, qualitative effectiveness of the equivalent single-car model is confirmed, and it is shown that the inter-vehicle lateral dampers installed under the gangway have the possibility to reduce the vibration in tunnel and improve the riding comfort.
