| Abstract: | Taking aim at the MG750-1915 GWD shearer,the fault tree model of traction unit has been established.The occurrence probability of every fault mode, unreliability and unavailability of traction unit are quantitatively studied by using the reliability software RELEX.Based on the results of analysis,the components of high probability of fault may be improved for enhancing the reliability of whole traction unit. |
