Abstract
Recently, tilting system of car body has been adopted in here and there in order to improve riding comfort. Tilting system has the ability of independently doing an tilting motion. so it ensured high reliability and safety so that it may not inhibit the riding comfort. But, in order to attempt further improvement of reliability, we have been studied the condition monitoring system with data processing. In this report, first to begin with the basic concept of condition monitoring system for composition rolling stock set is described. Here judgment technique of the line shape for condition monitoring is discussed in detail. In continueing, system constitution method and actual car test result are described. From car test result, a promising knowledge for future system constitution is obtained.
