Finite Element Modeling of Steel Cord in Engineering Radial Tires Using Parametric Equations

The finite element method provides feasibility for the analysis of complex structures, specifically for helical wire rope structures like radial tire cords. For models with specific pitch length and rotation radius, it is usually very difficult to complete helical wire rope models with good interface contact characteristics. In the present work, parametric equations were developed to establish geometric model of steel cord considering the distance between the centerlines of the core and the strands to prevent the strands from interfering. The minimum rotation radius was determined by considering the effect of pitch length. The finite element method was used to analyze the deformation and stress distribution of radial tire steel cord. This study can provide support for rapid establishment of helical models.
