  • A NOVEL AND FLEXIBLE DESIGN OF MAGNETOSTRICTIVE SENSOR FOR Strand/Rope DEFECT INSPECTION
    2015
    Co-Authors: X. J. Wang, D. Wang
    Abstract:

    Steel Strands and Ropes are widely used to support heavy structures, such as bridges, buildings, lifts, and cable cars. They are also used in transmission lines to deliver power to cities as well as electrical trains. Failures occurring in Strands/Ropes may cause serious casualties and suspension of services. Therefore, it is of prime concern to provide advanced warnings prior to fatal failures. Magnetostrictive sensor (MsS) has become popular in generating and receiving desired ultrasonic guided waves to detect Strand/Rope defects. Conventional MsS usually uses hard sensing coils to generate the necessary dynamic magnet field to excite the desired guided waves for defect inspection. However, the hard coils are bulky and difficult to install on Strands/Ropes with different diameters. Such inflexibilities limit the use of MsS in man

However, the hard coils are bulky and difficult to install on Strands/Ropes with different diameters. Such inflexibilities limit the use of MsS in many practical situations. This paper reports the design of a new type of MsS that uses innovative flexible coils, called flexible printed coil (FPC). The FPC is made of flexible film with the desired printed circuit pattern so that it can replace the conventional hard coils. The FPC-based MsS can be easily installed on or removed from the inspected Strand/cable because of its flexible structure and the wrapped around type of mounting fashion. Moreover, the inspection performance of the new FPC-based MsS has been greatly increased because the FPC can be wrapped into multiple layers. The more the layers, the higher the wave energy can be emitted. The results obtained from the experiments conducted on seven-wire steel Strand samples have proven the superior abilities of FPC than the conventional hard coils. The multi-layer FPC-based MsS has longer inspection range and higher sensitivity in detecting small cracks.Copyright © 2011 by ASME

  • Tension/Torsion Interactions in Multicomponent Mooring Lines
    Offshore Technology Conference, 2013
    Co-Authors: C.r. Chaplin, G. Rebel, I. M. L Ridge
    Abstract:

    Six Strand Ropes generate torque under tension. This can lead to transfer of twist to other mooring line components, either permanently, or dynamically. The effects of this imposed twist can seriously affect strength and fatigue endurance. In order to predict the torsional interactions between components it is necessary to quantify the tension/torsion behavior of all the different categories of mooring line component, not just the six Strand Rope. This paper discusses the problems of torsional interaction and presents results of measurements of tension/torsion behavior of six Strand Rope, stud link chain and a PET fiber Rope.

  • Wire strain variations in normal and overloaded Ropes in tension-tension fatigue and their effect on endurance
    Journal of Strain Analysis for Engineering Design, 2005
    Co-Authors: J. J Evans, I. M. L Ridge, C.r. Chaplin
    Abstract:

    This paper investigates wire strain variations in tension-tension fatigue for two six-Strand Rope constructions under normal and overloaded conditions. It has been found that for Ropes in tension there is a considerable variation in wire strains both on different wires at the same cross-section and to a marginally lesser extent along the length of the same wire. It has also been found that a Lang's lay Rope has a wider variation of strains than the identical ordinary lay Rope. Load cycling has been found to reduce the distribution slightly for an initial period, around 8 per cent of the Rope's life (for the load range used), after which the variations in wire strains do not change significantly for the rest of the life of the Rope. Tests involving initial overload have shown a considerable reduction in wire strain variation. By way of an example for an ordinary lay Rope an initial overload caused the wire strain standard deviation to decrease from 22 per cent of mean to 11 per cent of mean and was accompa...
