Assessing the number of twists of stranded wires using ultrasound

Wiring, of different degrees complexity, is a dominant part mechanical support in constructions, electromagnetic and telecommunication signal transmission cables, among other applications. Single manifold twisted wires are prominent examples such utilities susceptible to irritations deterioration. They require ultrasonic non-destructive testing health monitoring. The objective develop an ultrasound-based technique automatically measure the number twists per meter winded wire strands implementable industry, be used during scan provide cable production, for instance, verify that calibration still place. Fourier transformation applied as expedited method wires. Digital processing obtain spatial time spectral representation recognition due amplitude variance, induced by varying distance between transducer wire, developed depending on twists. Two analyses satisfactorily quantify providing each twist. robust applicable when strand not constant, industry requires.
