Fault Tree Analysis of Shearer Pump Start

Guo Da

Abstract

When shearer is powered on, shearer pump always is failed to start. Fault tree model is established in view of this situation. Probability, unavailability and unreliability of every fault event are quantitatively researched by MATAB, which is used as analysis platform for system reliability. At the same time, analysis results are discussed in this paper and used to improve performance of electrical modules, which are high failure rate. As a result, the overall system reliability is improved.
