摘要
通过试验和理论分析,研究了随机疲劳载荷的小载荷取舍标准、载荷之间的相互作用效应和顺序效应对疲劳损伤的影响。最后提出了与随机载荷历程等效的疲劳谱的编制方法及准则。
By experiment and theoretic analysis,the present paper studied the criterion for omitting small loads in the random fatigue loads,and the influence of interactive and sequential effects among the loads on the fa- tigue damage.At last,it were put forward the criteria and methods for constructing fatigue load spectrum which had equal damage with the random load course.
