| 摘 要： | 对某型飞机新成型座舱盖及使用后座舱盖有机玻璃的疲劳性能进行了试验研究.利用升降法试验得到了指定目标寿命下两种不同情况有机玻璃的条件疲劳极限,利用三参数法拟合得到了两种情况有机玻璃的S-N曲线.对新成型座舱盖及使用后座舱盖有机玻璃的疲劳性能进行了对比分析.对比分析的结果表明,与新成型座舱盖相比,使用后座舱盖有机玻璃的疲劳性能没有显著下降.

| Abstract: | Fatigue properties of the newly-formed and served canopy PMMA,which is applied in a certain airplane,are studied with an experimental method.In order to gain the fatigue strength in the designated life,experiments on up and down method had been conducted.The S-N curves of the PMMA were acquired based on three-parameter exponential function.Fatigue properties of the canopy PMMA in the two different condition of service were discussed.The results of analysis showed that fatigue properties of the served PMMA d... |
