Parametric modeling and finite element analysis of triangular strand wire rope

The triangular strand wire rope exhibits superior performance and holds substantial potential over its round strand counterpart, which is brought by its unique and excellent structural design. However, the investigation of specialized strand components with such distinctive shapes remains limited, and the predominant challenge resides in modeling. This paper introduces a precise vector expression for the spatial trajectory of distinct steel wire types within the triangular strand wire rope structure. Moreover, a comprehensive suite of parametric modeling methodologies tailored for finite element analysis have been established, based on ABAQUS/CAE. The finite element model has been validated by experiments. Furthermore, a series of examples with various boundary conditions and parameters are intended to evaluate the factors affecting the accuracy of the FE model. Employing the established parametric modeling method, triangular strand wire ropes with a range of lay length were established, the differences in their mechanical properties under tensile load were compared, yielding insights that form the basis for proposed design considerations regarding lay length ratios. This model is apt for investigating the macroscopic mechanical response and local force characteristics of triangular strand wire ropes during typical service processes. Moreover, its versatility extends to the realm of other complex rope structures, promising to address the behavioral analysis of intricate strands and rope configurations.
