In this study, discard lifetimes of 6 × 36 Warrington-Seale steel wire ropes subjected to bending over sheave (BoS) fatigue have been determined theoretically and experimentally. Multiple linear regression model has been devised and novel theoretical discard life prediction equation has been presented by using the least square method. The results indicate that there is a powerful correlation between the results obtained by theoretical model and experimental data. The theoretical discard life prediction equation results can be used in the range of specific tensile loads investigated and diameter ratios used with acceptable error when the values of coefficient of determination (r2) and correlation coefficient (r) are considered.
Key words: Discard fatigue life / stranded steel wire rope / regression analysis
