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.

Description

technical field [0001] The invention belongs to the relevant technical field in the field of large-scale production equipment monitoring, and in particular relates to a fatigue failure algorithm for large-scale tower crane cables. Background technique [0002] After obtaining the cable state information through the optical fiber sensing equipment, further diagnosis and analysis to extract the state characteristic information of the cable is the key to realize the cable evaluation. The diagnosis methods mainly include conventional cable fault diagnosis and diagnosis methods based on artificial neural network. adapt to learning ability. [0003] The existing fatigue failure algorithm technology of large tower crane cables has the following problems: the existing fatigue failure algorithm of large tower crane cables cannot operate well on the fatigue of various aspects during work, which may cause rope failure. Too much fatigue may cause the rope to fall off when it cracks se...
