Reliability analysis for an EHCS of automatic transmission based on GO method

The expanded GO method for multi-functional repairable systems is proposed in this paper. The expanded method was used to analyze the electro-hydraulic control system of an automatic transmission which has the characteristics of multi-function and repairability, and the minimal cut-sets and availability are obtained by the qualitative and quantitative analysis of the method. Finally, the qualitative and quantitative analysis results of the expanded GO method are compared with the qualitative analysis results of FTA and the quantitative analysis results of Monte Carlo to verify its accuracy and applicability.
