A Methodology For Systems Reliability Estimation Through Condition Monitoring

Giuseppe Curcurù


Complex systems are constituted by many interconnected components and sub-systems. Optimization of the maintenance costs, improvement of the system reliability and safety are the main goals of the technical management. To this purposes, condition monitoring is one the most effective tools to be used both for an early detection of working anomalies and/or incipient failures and for increasing the system availability during the working activities. This paper proposes a methodology for modeling data coming from the monitoring system when Stress Wave technology is used in a naval vector. In particular, through the detection of Stress Wave Peak Amplitudes, a statistical model based on the mean values of such peaks, generated by friction or shock events, is proposed to be employed for system/component reliability estimation. The proposed methodology can be easily extended to a whatever real system. Finally, a numerical example is presented.
