考虑拆卸结构的动车组系统动态机会维修策略
A Dynamic Opportunistic Maintenance Strategy for Electric Multiple Unit Systems Considering Disassembly Structures
摘要
Abstract
To study the impact of disassembly structures on the maintenance planning of electric multiple unit(EMU)systems,a disassembly hybrid graph model is used to analyze the optimal disassembly sequence for individual components.Additionally,a cost-effectiveness analysis method is employed to select multi-level maintenance strategies,and the optimal reliability threshold of components,considering disassembly costs and installation/debugging costs,is calculated.On this basis,the concept of opportunity maintenance is introduced to address the problem of disassembly sequence planning for multiple components before maintenance.A multi-objective disassembly sequence optimization method is proposed,and a dynamic opportunistic maintenance strategy model considering waste of reliability value is established.Case analysis shows that compared to traditional sequential preventive maintenance strategies,the dynamic opportunistic maintenance strategy reduces downtime by 16 times through merging maintenance opportunities,effectively reducing downtime costs caused by excessive preventive maintenance and disassembly time.The total maintenance cost is saved by 16.6%,which can meet the economic requirements of maintenance departments and provide theoretical support for the study of maintenance strategies considering complex interdependencies in EMU systems.关键词
