基于GO-FLOW方法的转辙机部件预防性维修策略研究

Study on preventive maintenance strategy for switch machine components based on GO-FLOW method

为解决目前转辙机因采用固定时间间隔的预防性维修导致的维修资源浪费及潜在人为失误造成的安全隐患,提出一种基于GO-FLOW方法的转辙机部件预防性维修策略;依据转辙机的组成结构和工作流程,建立转辙机GO-FLOW模型,在设备整体可靠性约束下,利用故障统计数据,计算在不同服役时间段内转辙机主要部件的可靠度,据此确定维修时间间隔变化的转辙机部件预防性维修方案,以实施针对性维修,更好地平衡维修经济性和安全性。

To deal with maintenance resources waste and potential human error hazards caused by fixed-interval preventive maintenance of switch machine components,a preventive maintenance strategy for switch machine components based on the GO-FLOW model is proposed.According to the composition,structure and working flow of the switch machine,a GO-FLOW model of the switch machine is constructed.Under the constraints of overall reliability of the switch machine,the degree of reliability of major components of the switch machine in different servicing periods can be quantitatively derived by use of failure statistics.Based on that,the preventive maintenance plan for switch machine components at variant maintenance intervals can be formulated so as to make more targeted maintenance,better balancing the economy and safety of maintenance.
