“…Only few works, instead, considered the evolution of plastic deformations under axial-torsional loads. Jiang et al ( [13], [14], [15]) proposed a refined finite element (FE) approach, which takes into account plastic deformations and allow for an accurate description of internal contact conditions.

AbstractIn this work a new formulation for modelling the elastic-plastic behaviour of metallic strands subjected to axial-torsional loads is presented. Simple and accurate cross sectional constitutive equations are derived, fully accounting for the evolution of plastic deformations in the wires, starting from a description of the internal structure of the strand. The proposed approach is suitable both for straightforward analytical calculations as well as for implementation into finite elements for the large-scale structural analyses of cable structures. A full three-dimensional (3D) finite element (FE) model, based on a parametric description of the strand internal geometry, is also developed.

“…The 1 x 7 is the basic strand construction which contains 7 individual wires wrapped in a right or left lay direction. Since there are many parameters which can be varied in the construction of a rope strand, it is important to have a general and accurate model which can predict the effects of possible variations of these parameters on the performance of the strand [9]. The solid models of the right and left lay wire ropes were developed and used to perform the simulations in ANSYSTM, so that the behavior of the wire rope at the application of torque could be studied.…”

Analysis of optimum wire rope configuration for equal unidirectional torsional stiffness for flexible steering shaft

Abstract. The design and modeling of Low Stiffness Resilience Shaft (LSRS) for the Semi-Active Steering (SAS) system using wire ropes is discussed in this paper, along with the static structural torsion test simulation of the wire ropes in order to determine the best possible configuration which serves the purpose of an LSRS. The importance of this study arises due to the unidirectional torsional properties of a wire rope. For an effective operational LSRS, the wire ropes need to have similar angular deflection in both the clockwise and anti-clockwise direction. LSRS, an integral component of the SAS is a flexible shaft that can replace the conventional rigid shaft of the steering system and allows active control to be performed. 3D solid models of the simple strand and the 4 strand wire ropes used in finite element analysis were generated in CAD software SolidWorksTM. The single strand and the different configuration of wire ropes required to function the LSRS effectively were then analyzed using Finite element simulation in ANSYSTM. A single wire rope could not be used because its construction has inconsistency in the torsional stiffness in clockwise and anti-clockwise direction. The single-strand right-direction lay wire rope is found to have 16.05% angular deflection percentage difference in the clockwise and anticlockwise directions which indicates that using a single strand wire rope for the LSRS will cause the vehicle to have a variable response in the clockwise and anti clockwise direction upon turning the steering wheel. Due to this inconsistency, two variations namely Variation 1 and Variation 2 with arrangement of 4 strand wire rope were devised so that the angular deflection percentage difference would be negligible. Simulation results indicated that Variation 1 of the two variations with an angular deflection percentage difference of 0.34% in the clockwise and anti-clockwise direction respectively is best suited for the use in LSRS as it has almost negligible angular deflection percentage difference and will allow the vehicle to have similar steering response in the clockwise and anti-clockwise direction.

“…Numerical applications of the proposed cross sectional and finite element formulations are then presented for the case of a well documented steel strand, extensively studied in literature both for a combination of axial-torsional loads [4,15,16,19,20] as well as under the combined action of axial load and planar bending [9].…”

Abstract. A new formulation to model the mechanical response of metallic strands undergoing a combination of axial load and planar bending is developed. Each wire of the strand is modeled as an elastic curved thin rod. A kinematic model is then introduced to relate the generalized strain variables of the strand to those of the wires. The stress-strain state of the wires is evaluated starting from the analysis of the internal contact conditions. Friction is modeled through the classic Amontons-Coulomb law and the elastic tangential compliance of contact patches is accounted for. A non-holonomic material constitutive law in terms of
