| Abstract:The reliability of diesel electric governor is systematically analyzed using the Markov model. Failure Mode and Effects Analysis (FMEA) was carried out on the whole system based on each component to analyze the failure mode and its influence. The classification of diesel electric governor failures was put forward. In accordance with on line diagnostics and the maintenance characteristics of speed governing system, system maintenance ratio was introduced into the model. More comprehensive and efficient reliability analysis was carried out on the speed governor and limit state failure probability was obtained. The result shows that Markov model can be used to predict the reliability of diesel electric governor and guide system design. |
