Fatigue failure algorithm for large tower crane cable

Abstract

The invention discloses a fatigue failure algorithm for a large tower crane cable, which comprises an optical fiber sensing equipment module and a signal sending module; the output end of the opticalfiber sensing equipment module is a signal sending module; the signal sending module receives signals from the optical fiber sensing equipment module. The optical fiber sensing equipment module and the signal sending module are in a sending and receiving relationship; according to the algorithm provided by the invention, the fusion of the influence of the cable section size, the material elasticity modulus, the unit type and the thickness on the damage increment and the static loading condition is realized; therefore, the fatigue can be effectively controlled; compared with the existing specified value, the specified value is set for the threshold range of the upper limit or the lower limit of a certain parameter, the monitoring result of this time is compared with the operation data of the cable over the years, and the monitoring results of the same cable or the same type of cables are compared, so that better detection can be carried out.
