Numerical simulation and experimental study on stress deformation of braided wire rope

To explore the mechanical properties of braided wire rope, relevant theories of differential geometry are applied to deduce the space curve parametric equation of braided wire rope, specific to the structural features of the rope. On this basis, a geometric entity model of YS9-8 × 19 braided wire rope is established. Through mesh generation, a finite element model of braided wire rope is obtained. Constraints and loads are applied for numerical simulation calculations. The numerical simulation results are analyzed to reveal the stress and deformation distribution rules of the rope strands along the rope axis direction and on the cross sections of strands. Tensile tests of YS9-8 × 19 steel wire ropes are performed. The test data and the analogous simulation results coincide, verifying the rationality of the model. The study provides theoretical bases for subsequent frictional wear and life studies on this steel wire rope.
