Methods of Measuring the Mechanical Behavior of Wire Rope

摘要

Techniques were developed for the accurate measurement of load, elongation and torque generated in a wire rope during an axial static mode of tensile loading. Selection of parameter measurement systems was based upon the unique response of wire rope to axial loads. A tension-torque transducer was designed for the simultaneous but independent measurement of applied load and induced torque. An electro-optical tracking system was adapted for use as a rope extensometer. Measurement of elongation is performed continuously and directly upon a section of the rope. Furthermore, expendable electro-optical-targets permit extension measurements up to and including specimen rupture. Both measurement systems are capable of an accuracy of 1%. (Author)
