【Abstract】 After analysing the types and causes of routine faults with the eontact system, we, for the first time, establish the reliability model of the system by using relevant principles and methods of reliability engineering. Formulas on calculating the reliability indices of the single-side supply and the double-side supply are derived. A practical case is analysed to show that this mod-el can be used for qualitative evaluation and preliminary quantitative evaluation of the reliability of the contact system.更多还原
