摘要
分析了直升机承受高周疲劳载荷的特点及其关键动部件的高周疲劳特性,阐述了直升机使用飞行谱、疲劳载荷谱的编谱思想及疲劳寿命的评定方法。
Helicopter alternating fatigue loads and its critical component high-cycle fatigues are analyzed in this paper. The conception for developing helicopter flight and fatigue load spectrums, and the fatigue life evaluation are presented.
