摘要
根据焊接结构在各种随机谱载荷下长寿命区疲劳试验的有关资料，对变幅载荷下焊接结构在长寿命区疲劳累积损伤的分布规律进行了统计分析，根据长寿命区疲劳寿命高度离散性的特点。
According to the relative experimental data of welded structures in the long life range under a variety of random loading spectrums, the law of fatigue cumulation damage for the welded structures in the long life range under variable amplitude loading is analysed by the statistical method. On the high scattered feature of fatigue life in the long life range, a new probabilistic design model which has a changeable standard deviation is proposed.
