| 摘 要： | 针对当前飞机的腐蚀损伤评估模式，构建了一种较为合理的腐蚀管理全寿命分析模型。该模型可将全寿命阶段飞机结构可能遭受的各种腐蚀形态、MSD和结构材料性能随时间的退化作为变量纳入到一个框架中，提高了分析精度和可靠性，为新机定寿和老龄飞机延寿提供技术支持；方法具有一般性，可推广到其他装备结构寿命评定中。

| Abstract: | Based on the characteristic of corrosion of aircraft structure under service conditions,a fatigue holistic assessment model that can incorporate the effects of various corrosion damage and age-degradation into a systematic damage tolerance framework was established with existing engineering principles.The influence of age-degradation and fatigue interaction on aircraft structure integrality was quantified through this model.In the meantime,the predictive model of residual strength and crack growth of the wi... |
