  • Publication number: 20200190735
    Abstract: A stranded wire having a plurality of steel wires twisted together includes, in its cross section perpendicular to its longitudinal direction, a central wire as the steel wire, a plurality of first circumferential wires as the steel wires arranged in contact with the central wire to surround an outer periphery side of the central wire, and a plurality of second circumferential wires as the steel wires arranged in contact with the first circumferential wires to surround an outer periphery side of a region where the first circumferential wires are arranged, the second circumferential wires being greater in yield stress than the central wire and the first circumferential wires. The central wire is in surface contact with the first circumferential wires. The first circumferential wires are in surface contact with the second circumferential wires.

  • Patent number: 8890516
    Abstract: A tension measurement apparatus that can carry out tension measurement of superior reproducibility with high sensitivity even for a target object of a stranded wire structure is provided. A cylindrical magnetizer arranged to surround a portion of a long magnetic element that becomes the target object of measurement direct-current magnetizes the magnetic element in the longitudinal direction up to the range of approach to saturation magnetization. Using a Hall element (magnetic sensor) arranged in proximity to the magnetic element at the central region in the longitudinal direction of the magnetic domain, the spatial magnetic field intensity in the neighborhood of the surface of the magnetic element, greatly differing corresponding to stress variation, is detected. Based on the detection value, the tension acting on the magnetic element is measured. Accordingly, a measurement result of superior reproducibility with high sensitivity is obtained.
