Title Reliability Analysis of Metro Sliding Plug Door Based on FMECA
Abstract bWith the rapid development of urban rail transit, the safety of the metro has been paid more and more attention. The subway train door system as one of the key subsystem of the metro, reliability analysis of the door system to reduce the failure rate and find out the weak links of door design appears to be imperative.
First, this paper introduces each part of the sliding plug door and working principle of them. Then, the paper analysis the door system reliability modeling, and established the task reliability block diagram. Finally, I use FMECA method on the reliability analysis of the door system. In the FMECA analysis of the door system,we get the statistics of the door fault components to identify the main components of door system firstly, and then grade failure of the door system and give the calculation methods of the failure rate and failure effect probability. Finally, the analysis of failure mode effect and harmfulness for each failure mode in detail gets the larger hazard failure mode door system, and provides technical support for designing and repairing door system.
