1. Via using the loads above to construct load spectrum, the changes of amplitude and load phase angle can be taken into consideration.
2. Viewing the entire life time, except the first load, the rest are cycle of "".
3. The test lifetime between two trials of same load is 50 block spectrum at most.
4. The reason leading to different lifetime of A spectrum and B spectrum is not difference in order of high and low load, but the order of different phase angle load.
5. The closer the calculation result of one method to 1 is, the more precise the prediction is. |
