| 摘 要： | 为了提高供电系统的安全性和可靠性,CMS-03A新型中低速磁浮列车采用了一定量的冗余设计.考虑到动态故障树方法特别适合于冗余系统的故障建模,采用动态故障树方法对CMS-03A供电系统进行了故障分析.首先给出CMS-03A供电系统冗余设计方案,之后介绍动态故障树(DFTA)原理,然后用DFTA建立供电系统的故障模型,详细分析了该模型;文章的最后给出冗余设计方案与非冗余设计方案的对比分析,讨论了冗余设计方案的优劣.

| Abstract: | To improve the safety and reliability of the power supply system, redundant design is adopted for the CMS-03A mid-to-low speed maglev train. As the dynamic fault tree (DFTA) method is quite applicable for the fault modeling of the redundant system, the method is used for the fault analysis of CMS-03A power supply system. The redundant design scheme is given for the CMS-03A power supply system and then DFTA principle is illustrated. The fault model is also built and analyzed. Comparisons are made on the redundant and non-redundant design scheme. Advantages and disadvantages are discussed for the redundant design scheme. |
