在深入了解CMS-3型磁悬浮列车电源系统结构的基础上,建立了列车电源系统失效的故障树,引入功能相关门,表述该树中的特殊逻辑关系。提出划分动态子树,并转化为马尔可夫模型的可靠性分析法,对比分析了电源系统改进前后的可靠性。通过计算证明该电源系统设计符合磁悬浮列车在安全性和可靠性方面的要求。
Based on the deep understanding of the power system structure of CMS-3 magnetic levitation vehicle, the failure tree of train power system is established, and the function-related gates are introduced to express the special logic relations in this tree. The dynamic analysis method of partitioning dynamic subtree into Markov model is proposed, and the reliability of power system before and after the improvement is compared and analyzed. The calculation shows that the power system design meets the requirements of magnetic levitation trains for safety and reliability.
