• This paper describes with the improvement in reliability of the truck frame for Shinkansen trains. Vibration characteristic of high order of truck frame is clarified by the vibration modal analysis in order to improve the reliability on the strength of truck frame, and it is necessary to select structure and dimension of the truck frame which does not resonate for main vibration source. And, it is important that it makes of the welded bonding condition by the cutting of the truck frame in order to improve the quality of the welded joint, periodically and confirmation test and constructs the system that feeds back and can improve the result in the manufacturer. Though "Nozomi" business operation was started from the time schedule revision in March, 1992 by the Series 300 Shinkansen cars, there is no matter either, and the generation of the crack of the truck frame which originates from the design over the intervals about 11 is regarded as acquiring the very high reliability.
