“…static/dynamic) are applied to study a variety of complex behaviors and properties of strands/ropes that are beyond the capacity of analytical models. For instance, de Menezes et al [6] have applied a variety of models to predict the tensile/torsional/bending response of a single-layered strand under a wide range of helical angles and have systematically compared the models in terms of accuracy. The models have included an analytical model, a finite element model using beam elements, a finite element model using solid elements in a quasi-static setting and a finite element model using solid elements in a dynamical setting.…”

As an important part of transmission lines, preformed helical fitting plays an indispensable role in the safe and stable operation of electronic circuits. However, due to the poor service environment of transmission lines, preformed helical fitting can often slip, scatter, and detwist. This paper explores variations in the holding force of the preformed helical fitting under different geometric parameters. First, the geometric structure of preformed helical fitting is analyzed, and the secondary development is conducted using the ABAQUS finite element software. The script program is written in Python language to realize the parametric modeling. Based on the experimental results, the changing trend of the holding force is consistent, which confirms the correctness of the finite element model. In addition, the preformed helical fitting is studied under different values of molding aperture, pitch length, pitch number, and armor rod diameter, and changes in the holding force under different parameters are analyzed. The results show that the holding force of the preformed helical fitting increases with the decrease in the molding aperture and pitch length, and the molding aperture has a negative linear correlation with the overall holding force. The holding force increases linearly with the pitch number; so, reducing the pitch length can increase the holding force of preformed helical fitting. Moreover, the results indicate that the holding force increases with the armor rod diameter. The research results presented in this study have important guiding value for the design of performed helical fitting.

Using differential geometry theory, geometric modeling and finite element modeling of round strand and compacted strand before and after the rolling process are carried out. Using Costello theory, the rationality of the model is verified. The effects of five different friction factors on the mechanical properties of both were simulated and analyzed under the same axial tensile load. The results show that under the same axial tensile load and friction factor, the maximum equivalent stress and displacement of the compacted strand is smaller than those of round strand. When the axial load is 5 kN and the friction factor is 0, the maximum equivalent stress of the compacted strand relative to the round strand is reduced by 38.1%, and the displacement is reduced by 19.3%. Under the same axial tensile load and different friction factors, the maximum equivalent stress of the round strand increases approximately linearly with the friction factor; while the maximum equivalent stress of the compacted strand has a small increase between the friction factor of 0 and 0.05, and after 0.05 the maximum equivalent stress almost does not change. The displacement of both decreases as the friction factor increases. Under the same strain, the reaction force of the compacted strand is greater than that of the round strand, which proves that the compacted strand has higher tensile strength than the round strand.
