Abstract
The present invention relates to a method for monitoring axial loads in structures by identifying natural frequencies. The analyzed structures are made up of elements connected by means of contact and are subjected to tractive loads, such as mooring lines. The proposed method uses bench testing and a computer model of the structure to determine the variation in the natural frequencies in relation to the variation in load. Monitoring is carried out using vibration sensors, in particular accelerometers, laser position sensors or strain gauges, to measure the dynamic behaviour of the structure, a data capture and signal conditioning unit and a computer to correlate the load applied and the vibration behaviour using a computer algorithm, and also to present the result. The invention discloses an easy calibration method for the dimensional template of the structures in question, high accuracy and easy installation and operation in the field.
