Bending fatigue of locked coil ropes in the proximity of cast sockets: Part 1: Influence of tensile force and swinging angle

摘要

The ropes of many suspension structures are exposed to oscillations which cause increased alternating bending stresses at their ends. The aim of the tests carried out was to investigate how the alternating bending of a locked coil rope in the proximity of the cast socket affects its fatigue strength. In the tests a single locked coil rope was used (diameter 31mm, breaking strength 985kN). The compound cast sockets were tested both with and without soft lined protective sleeves which were attached at different distances in front of them.
