Rolling stock has been generally inspected and maintained on the basis of the preventive maintenance. However, the reliability of the sensors and information technology has drastically improved, and with this background the objective of this research is to develop the condition monitoring system for the bogies of the Shinkansen cars. This paper describes an algorithm for detecting fault in some parts of bogies. This scheme is based on the statistic analysis of vibration acceleration. This algorithm detects the signs of faults by examining the amplitude and duration of measured vibration acceleration. For examining the possibility to detect fault in the bogie, experiments simulating some fault modes in bogie parts are conducted in the rolling stock field simulator at Komaki Research Center of JR Central. From the results of these experiments, we can show the reliability and the validation of this scheme for monitoring conditions of Shinkansen bogies developed in this study.
