The Effect of Lay Length on the Antipull Performance of Steel Cords and the Spinning Loss Based on the FEM

This paper is mainly aimed at 0.28 + 6 × 0.26 steel cords and 0.26 + 6 × 0.24 steel cords under different lay length conditions through the ABAQUS finite element analysis software to limit the tensile performance of the steel cord and the stress field distribution during the tensile loading. Based on the finite meta-analysis, in this experiment, the tensile simulation of the same kind of steel cord at the twist lay length of 5 mm, 7 mm, 9 mm, 11 mm, 13 mm, and 15 mm was carried out under the condition of 2 mm/s. The results show that, under certain conditions of other process conditions, with the increase of the twisting distance of the steel cord strands, the strength of the steel cord increases, the deformability decreases, the stress concentration decreases, and the spinning loss decreases. The spinning loss formula is modified to reduce the calculation error.
