Abstract

The reliability of a hydraulic shovel system has been assessed through the application of fault-tree methodology. Fault-tree analysis assists in the evaluation of the reliability of a system or alternative designs and identifies critical components for system success and potential causes of system failure. It uses deductive reasoning to identify system failure. A reliability block diagram and fault tree of the shovel system were developed. An algorithm for obtaining the minimum cut set as well as the minimum path set from the fault tree is presented and the reliability of the machine and its sub-systems with time is evaluated. The analysis indicates room for improvement in different aspects of the machine.
