| Abstract: | 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. |
