Reliability Study of Friction Clutch Based on FMECA

In order to solve the problem of improper maintenance of the friction clutch system and affects the safety of ship navigation, the reliability of friction clutch is studied based on the failure mode, mechanism and hazard analysis method. The hardware hierarchical functional block diagram of friction clutch is established, and the statistical table of fault mode and fault mechanism analysis are obtained. The hazard matrix and product hazard method are used to analyze the hazard of fault mode respectively. The analysis results show that the components such as bearing bush, air bag and elastic element are the key factors affecting the reliability of the friction clutch system, providing a reference for the maintenance and diagnosis of the friction clutch system.
