Research on Preventive Maintenance Interval Decision of As Car Door System Based on Maintenance Cost
In order to ensure the safety of subway operation,regular maintenance strategies are commonly a-dopted by subway operating enterprises.Regular maintenance strategies can lead to situations of excessive and insufficient maintenance.Reasonable maintenance interval decisions can be made to reduce the problems of exces-sive and insufficient maintenance,which is beneficial for cost reduction,efficiency improvement,and safe and re-liable operation of vehicles.This article establishes a fault distribution model and reliability function for the door system of As subway vehicles based on historical fault data.According to the fault distribution model and relia-bility eigenvalue of the door system,considering the maintenance economy and availability requirements of metro vehicles,a preventive maintenance interval Decision model based on maintenance cost is established to analyze and obtain the feasible optimal preventive maintenance interval decision-making.
