Fault Detection for Vehicle Suspensions Based on System Dynamic Interactions
نویسنده
چکیده
This paper presents a novel method for the fault detection and isolation for rail vehicle suspensions that explores the additional dynamic interactions between different motions of a bogie or body caused by the failure of suspension components by taking advantage of symmetrical mechanical configurations of railway bogies. The study is focused on the monitoring of the vertical primary suspensions of a conventional bogie vehicle to demonstrate the general principle and effectiveness of the proposed method in detecting damper faults, although the technique is equally applicable for suspensions in other directions.
