چکیده

This paper demonstrates the possibility to detect suspension failures of railway vehicles using a multiple-model approach from on-board measurement data. The railway vehicle model used includes the lateral and yaw motions of the wheelsets and bogie, and the lateral motion of the vehicle body, with sensors measuring the lateral acceleration and yaw rate of the bogie, and lateral acceleration of the body. The detection algorithm is formulated based on the Interacting Multiple-Model (IMM) algorithm. The IMM method has been applied for detecting faults in vehicle suspension systems in a simulation study. The mode probabilities and states of vehicle suspension systems are estimated based on a Kalman Filter (KF). This algorithm is evaluated in simulation examples. Simulation results indicate that the algorithm effectively detects on-board faults of railway vehicle suspension systems.

Model-based Condition Monitoring for Railway Vehicle Systems

Although modelling techniques for railway vehicle dynamics are well-developed, much of the development in railway vehicle condition monitoring has relied on the knowledge-based techniques where no analytical system model is employed and only qualitative or empirical system knowledge are used for fault diagnosis. In this paper, the model-based approach is proposed as an alternative for railway v...
