摘要
本文提出了两种预测电磁透波复合材料结构疲劳寿命的方法,即定性预测方法和定量预测方法,并结合ARJ21-700飞机机头雷达罩对定量预测方法进行了详细说明。通过这两种方法,能够准确地预测疲劳寿命,有效地保证了产品的安全性和耐久性。
Two different methods of prediction for fatigue life of electromagnetic wave-transmitting composites structure is developed in this paper,qualitative and measurable.Measurable method is applied in the life prediction of ARJ21 nose radome.Fatigue life of electromagnetic wave-transmitting composites structure is estimated accurately by using these methods.This study can assure safety and durability of composites structure.
