Abstract

The development of the Chinese high-speed railway has experienced considerable dynamics in recent years. Further development of the trains depends to a large extent on the optimization of the key subsystems and monitoring of reliability and safety. In this paper the sample identification based health monitoring method for fault diagnosis and health monitoring by use of a Modelica based model of the train system is addressed. In this study the proposed method solved the issue of generating enough fault samples for health monitoring and be validated by the train operation real time data. The paper demonstrates the applicability of the method and modeling concept by means of diagnosis and monitoring of the state of health of the braking system.
