| Abstract: | Steel
wire ropes are used in elevators, cranes, mine hoistings, bridges, offshore and
aerial ropeway systems. In this study, bending over sheave (BoS) fatigue
lifetimes of 6 × 36 Warrington-Seale steel wire ropes have been determined
theoretically and experimentally. Experimental findings have critical
importance in identifying behavior of wire rope subjected to bending over
sheave fatigue. Experimental studies have been performed to show effects of
tensile load and sheave diameter parameters on BoS fatigue lifetimes of 6 × 36
Warrington-Seale steel wire ropes. Besides, a multiple linear regression model
has been devised and novel theoretical BoS fatigue 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 BoS fatigue lifetime results can be used in
the range of specific tensile loads investigated and diameter ratios used with
acceptable error. |
