Abstract
Two cycle counting algorithms, based on Range Pair and Rainflow methodologies, are quantitatively compared using three typical automotive load histories. Both algorithms were found to produce essentially equivalent counted spectra based on the resultant amplitude exceedance data. Because of the output format, the range pair algorithm is generally recommended for applications requiring damage accumulation calculations and spectrum analysis. The rainflow algorithm is recommended for applications involving cycle counting of arbitrary duration field load histories.
