Bridge electromechanical equipment maintenance method for long-term performance

The invention discloses a long-term performance-oriented bridge electromechanical equipment maintenance method. The method comprises the following steps of: 1, establishing an equipment reliability model; 2, establishing a strategy-to-equipment reliability correction model; 3, establishing a maintenance comprehensive cost optimization index; and 4, analyzing a bridge electromechanical dynamic maintenance strategy. The method has the beneficial effects that the influence of equipment importance, redundancy and reliability maintenance strategies is fully considered, the sum of the direct cost of long-term maintenance and the indirect cost of social influence is taken as a strategy evaluation index on the premise of ensuring that the perfectness ratio meets the bridge operation requirements, the maintenance strategies are selected, and the maintenance efficiency is improved. Therefore, the operation safety of the whole facility and the economical efficiency of the maintenance activity are ensured. 本发明公开了面向长期性能的桥
