Reliability Assessment for the Braking System of EMUs Based on SmallSample Size and GO Method

摘要

In order to solve the reliability evaluation problem of the braking system of EMUs, the GO-ss method hasbeen proposed in this paper. In the proposed method, multi-Bayes theory is applied to analyze the failure rate of key componentbrake controller under small sample. And then, the braking system is assessed based on GO method to achieve thereliability assessment of EMUs brake control system. Finally, the results of experiment and test data validate that thismethod can solve the reliability evaluation problem of the braking system, which provides a theoretical basis for the safeoperation of the braking system of EMUs.
