Fault Tree Analysis of Shearer Pilot Circuit for MG750/1915-GWD

Xiaojun Zhang

Abstract

Fault tree model of shearer pilot circuit is established for MG750/1915-GWD.Probability、unavailability and unreliability of every fault event are quantitatively researched by Relex Studio,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.
