Abstract :
With the theories of reliability mathematics, reliability system engineering and machine design, the paper presents the reliability analysis on the electrode plates driving system of the water resistance test system of high speed diesel locomotive. Stress strength interference theory and item stress analysis are applied to its mechanical and electrical parts to derive reliability calculation formulae. The probability models of system life are established and the reliability prediction is worked out. The life curve is arrived to indicate the relations between the reliability and the working hours of the system. The results show that the system is of high reliability, which declines with the increasing of working hours, and is mainly influenced by reliability of electric parts, with an enough life in mechanical parts.
