<p>To more accurately and more simply realize data collection and analysis for analyzing fatigue phenomenon of materials by the Rainflow Method, strain signals from a strain detecting means attached to an object for analyzing fatigue is A/D-converted at predetermined intervals, a peak of the A/D-converted strain signal is sampled, the peak value is detected, a valley is sampled, the valley value is detected, the difference between the peak value and the valley value is calculated, count values for respective levels are calculated in accordance with the magnitudes of the differences and the count values at the respective levels are written to a memory card detachably provided to the main body of the device of sampling data. <IMAGE></p> |
