摘要

为保证混合动力内燃机车可靠性设计要求，针对其关键部件动力电池系统进行了全面分析，对影响其可靠性的关键因素进行了有效识别。首先，基于故障树分析法FTA建立了动力电池系统故障树模型，得出各因素对动力电池系统安全风险影响程度；其次，基于FTA分析结果，结合层次分析法，建立系统层次结构模型，计算出影响动力电池系统可靠性的关键因素；最后，根据可靠性分析结果对动力电池系统提出优化方案。文章的设计理念为混合动力内燃机车的动力电池系统可靠性设计提供了理论依据和实际设计指导意见。

Abstract

In order to ensure the reliability design requirements of hybrid locomotives, the key components of the power battery system were comprehensively analyzed, and the key factors affecting its reliability were effectively identified. Firstly, based on the fault tree analysis (FTA) method, a fault tree model of the power battery system was established to arrive at the degree of impact of various factors on the safety risk of power battery system. Secondly, based on the results of FTA analysis, combined with the hierarchical analysis method, the system hierarchy model was established to calculate the key factors affecting the reliability of the power battery system. Finally, according to the reliability analysis results, the optimization scheme was put forward for the power battery system reliability design of hybrid locomotives, which provides theoretical basis and practical design guidance.
