Load-Bearing Capacity Modelling and Testing of Single-Stranded Wire Rope

important factor for the precise rope design. This value mainly
depends on the rope cross-section and the strength class. The
nominal value of the load-bearing capacity can be found in the
standards. However, this value is on the side of safety. For new rope
constructions or improvements in production technology, it is
suitable to determine the real value of load-bearing capacity. In this
paper, we present two approaches, how to determine the real value
of the load-bearing capacity related to the single-stranded wire rope.
The first approach is based on a simplified experiment using a
tensile test. This phase of the research is divided into two separate
experiments. The first experiment is focused on tests of individual
wires forming the rope. The second experiment is designed to test
the entire wire rope.
Finally, the second approach uses the finite element method to
create a computer model is presented. Since the rope tensile test is a
strongly non-linear task, the solver LS-DYNA with an explicit time
integration technique is used for simulation of the experiment. The
results from both presented approaches are compared
With the nominal value. Designed experiment for testing the whole
rope and computer modeling method is created based on the
practical requirements from industry, and the obtained results will
be reflected in the design of new types of wire ropes.
