摘要
提出对实测载荷谱进行计数处理的雨流 -回线法 ,使用该法能够简便地将实测载荷谱分离出独立的完整应力循环 ;并提出了二维疲劳载荷分布假设检验及其参数估计方法。最后 。
A rainflow loop method to make counting treament to load spectrum of actual measurement is presented. By means of this method, the load spectrum can be conveniently separated into the complete and independent stress cycles. A hypothesis test method for the two dimensional fatigue load distribution and a parameter estimation method are given. At last, their practical examples are presented.
