摘　　要：为解决某机型飞机空调系统故障频发的问题,选择空调系统中的重要部件热交换器作为研究对象。在现有维护方案的基础上,尝试对热交换器维护周期进行优化,基于可靠度、有效性以及经济性等角度优化维护周期,促使维护周期更为合理。首先,利用某航空公司连续两年热交换器故障数据进行数据拟合,找出符合故障模式的分布函数,利用K-S检验法验证拟合结果;其次,利用线性回归分析计算出故障函数的具体参数,以确定具体的函数表达式;再次,分别基于可靠度、有效性以及经济性,利用故障函数计算出基于不同维度的三种维护周期;最后,利用模糊决策法综合考虑三个因素确定最终的维护周期,实现维护方案的优化。结果表明:现行的维护模式将对航班正常运行产生不利影响,使用经过优化的维护周期可以让维护工作更加贴合实际情况。该优化设计为解决飞机空调系统故障频发问题和保障飞行舒适度提供参考。To address the faults in the aircraft air conditioning system, this study focuses on the heat exchangers, an important component of the system. The maintenance cycle is optimized based on existing maintenance strategies to enhance reliability, effectiveness and the maintenance cost. Firstly, fault data from an airline over two consecutive years are fitted to determine an appropriate distribution function describing the faults pattern, with the fitting results validated by using the K-S test. Secondly, linear regression analysis is used to determine the specific parameters of the faults function and its mathematical expression. The fault function is then used to calculate three maintenance cycles in different dimensions based on different parameters, including reliability, effectiveness and cost. Finally, the fuzzy decision-making method is employed to determine the final maintenance cycles based on these three factors, to optimize the maintenance strategy. The results show that the existing maintenance model has negative impacts on flight operations, while the optimized maintenance cycle effectively aligns with the practical conditions. The proposed optimization provides valuable insights for mitigating the frequent faults in aircraft air conditioning systems and enhancing flight comfort.
