| 中文摘要: |
| 目的 评定飞机日历寿命,测定飞机典型结构件的地面停放系数随日历年限的变化规律(C-T 曲线)。 方法 针对典型飞机结构连接件,首先在实验室条件下采用加速腐蚀的预腐蚀试验及预腐蚀后的疲劳试验,得到不同加速当量腐蚀年限下的疲劳寿命,然后对疲劳试验数据进行统计及处理。 结果 最后拟合得到飞机典型结构件的地面停放系数随日历年限的变化规律曲线。结论 通过 C-T 曲线可为某型飞机的定寿提供基础。 |

| Objective To evaluate aircraft calendar life, and to determine the change rule of local parking coefficient with calendar years (C-T curve). Methods Targeting at the typical aircraft structural connector, precorrosion test with accelerated corrosion and fatigue test after precorrosion were conducted under laboratory conditions, and fatigue life in different equivalent corrosion duration was obtained. Then the fatigue test data was statistically analyzed. Results Fatigue test data was statistical processed and C-T curve was fitted. The determination of C-T curve establish the foundation of the aircraft calendar life evaluation. Conclusion The C-T curve can provide a basis for life determination of an aircraft. |
