ABSTRACT

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