Abstract
This study mainly conducts the research on the discontinuous contact elastic properties of wire rope based on WR‐CVT. The geometry model and finite element model of continuous contact and discontinuous contact of 2/3 lay pitch wire rope are established. And the contact stress distribution of the steel wire is analyzed through 5 sections and 5 contact points. The results show that on the C‐C plane, the contact stress of the discontinuous contact model is 229.4 MPa higher than that of the continuous contact, but this difference is not obvious on the D‐D plane. The contact stress nephogram is elliptical, but in the noncontact area, the shape of the contact trace shows a distinct noncomplete ellipse, and the contact trace is distributed along the spiral trajectory of the steel wire. Point 4 due to the reduction in contact area, compared with continuous contact, discontinuous contact shows a higher stress value. The geometric dimensions of the wear scars of continuous contact and discontinuous contact indicate that regardless of the length of the wear scar or the width of the wear scar, the geometric characteristics of steel wire wear mark in discontinuous contact are larger than that in continuous contact, so the discontinuous contact aggravates the surface wear of wire. This research lays a theoretical foundation for the discontinuous contact wear and fatigue of WR‐CVT wire rope and other components.
Highlights
Steel wire rope is widely used in mine lifting, elevator, ropeway, and other industries due to its excellent tensile, torsion, and bending resistance
Because wire rope continuously variable transmission (WR-CVT) is evolved from MB-CVT, WR-CVT is mainly used in passenger car transmission
Chen et al [2, 3] analyzed the bending mechanical properties of triangular and circular steel wire strands based on the structural characteristics of the strands, the elasticity of the steel wire material, and the frictional contact between the steel wires and other factors. e finite element models of two kinds of steel wire strands were established, and the bending mechanical properties of two kinds of steel wire strands with the same twist angle and total steel wire sectional area were analyzed
Summary
Steel wire rope is widely used in mine lifting, elevator, ropeway, and other industries due to its excellent tensile, torsion, and bending resistance. Its flexible characteristics are designed and applied to the wire rope continuously variable transmission (WR-CVT) [1]. E WR-CVT researched in this study is applied in the field of passenger car transmission. Metal belt continuously variable transmission (MBCVT) is widely used in passenger cars as an ideal vehicle transmission device, and our team scholars proposed WRCVT. E wear of the steel wire rope is an important factor restricting the service life and reliability of the steel wire rope because the mechanical properties of the material have a decisive effect on the use of the steel wire rope. Chen et al [2, 3] analyzed the bending mechanical properties of triangular and circular steel wire strands based on the structural characteristics of the strands, the elasticity of the steel wire material, and the frictional contact between the steel wires and other factors. Zhang et al [4] conducted a study on the wear failure behavior of wire rope subjected to variable loads under bending and found that the outer steel wire rope and Advances in Materials Science and Engineering (a)
