Abstract
A new geometry design method of three-layered Seale wire strand is proposed.
The included angle between adjacent helical wires in the same layer, which is
assumed as zero in the conventional design method, can be predefined
arbitrarily by using the new method. The key process of deriving the diameter
ratio of each layer wires was formulated into a one-dimensional problem and
golden section method was applied to solve the problem efficiently. Finite
element analysis of the newly developed three-layered Seale strand was also
implemented by using a concise finite element model (FEM) which takes full
advantage of the helical symmetry and cyclic symmetry of the three-layered
Seale strand analysed in this paper. Three-dimensional solid brick elements
were used for structural discretization. Nonlinear factors such as inter-wire
contact and material plasticity were also taken into account. Numerical results
show that the circumferential angle of helical wires is very small for the threelayered Seale strand subjected to axial tensile loads. For the 19-wire Seale
strand loaded in the linear region, when included angle is predefined beyond
0.0042°, it can be ensured that the helical wires in the same layer will not touch
each other.
