Effects of different lay angles on characteristic fatigue responses of steel wire ropes

This paper establishes the effects of different lay angles of steel wire ropes on the resulting damage modes and fatigue fracture characteristics. For this purpose, seven-wire strand (1×7) wire ropes with left lay arrangement and lay angles, a of 11°, 18° and 24° were simulated using finite element...

For this purpose, seven-wire strand (1×7) wire ropes with left lay arrangement and lay angles, a of 11°, 18° and 24° were simulated using finite element (FE) method. Axial load cycles (Pmax = 0.144 minimum breaking load (MBL), R=0.1) along with the Coulomb friction µ of 0.5 between the contacted drawn steel wires are assumed. Results showed that the peak contact pressure, corresponding to the maximum applied load, varies from 1936 to 327 MPa when the lay angle is changed from 11° to 24°.

The wire rope with the lay angle of 24° experiences the smallest load-displacement hysteresis loop with the relative displacement range of 22 µm.
