| 摘 要： | 针对飞机结构的损伤容限设计特点,提出了采用不等间隔的检测策略,同时考虑了不同检测等级的不同检测完备程度对飞机结构维修费用和维修决策的影响.研究了在此策略下的不同更新情况和相应的更新概率,以检测间隔、首检期系数和检测等级为优化变量,期望维修费用率为目标函数,建立了基于不完备检测的飞机结构维修优化模型.通过实例验证了模型的有效性和经济性.

| Abstract: | Based on the damage tolerant design of the aircraft structure,a check policy of non-periodic intervals is presented and different inspection levels are considered to have different effects on the maintenance cost and decision-making.Then,the renewal probability of the aircraft structure is studied.Furthermore,the inspection interval,the threshold coefficient and the inspection level are chosen as the optimized variables.And the optimal maintenance model of the aircraft structure based on imperfect inspectio... |
