| 摘 要： | 为研究动车组受电弓在不同运营阶段的故障分布规律,文章以CRH3型动车组受电弓在不同运行阶段的两组故障数据为基础,运用最小二乘法分析故障数据的分布规律。计算结果表明,动车组受电弓故障数据服从威布尔分布;动车组受电弓在早期运营阶段故障率高,后期运营阶段故障率逐渐降低。本文的分析结果可以为不同运营阶段的动车组检修与故障预测提供理论依据。

| Abstract: | In order to study the fault distribution law of EMU pantograph in different operation stages, based on the fault data of CRH3 EMU pantograph in two different operation stages, this paper analyzed the fault distribution law with the least square estimation method. The calculation results show that the pantograph fault data of EMU obey Weibull distribution, in the early operation stage, the failure rate is high and the failure occurs frequently, and the failure rate decreases gradually in the later operation stage. By using the method of reliability data analysis, the fault distribution in different stages can provide theoretical basis for the maintenance and fault prediction of EMU running on line at different times. |
