Abstract
In this paper, we consider fault detection issue for Rail Vehicle Suspension Systems. The faults considered are the secondary vertical damper fault, the vertical spring fault and sensor failure. A Kalman filter is applied to generate the residual for fault detection. When there is a detectable fault, the observer sends an alarm signal if the residual evaluation is larger than a predefined threshold. The effectiveness of the proposed approach is demonstrated by simulation results for several fault scenarios.Keywords
