| The main way of mooring marine equipment is that the mooring cable passes through the guide pulley to realize the connection between the cable winder on the ship and the bollard of the wharf. The work aims to study the real-time monitoring technology and device of cable tension to ensure the mooring safety of marine equipment. With the pulley shaft, the main load-bearing member of the guide pulley, as the research object, the pulley shaft structure was reformed on the premise of ensuring the structural strength, and new structures and devices for monitoring the cable tension were developed. Solution to shear problem of the pulley shaft with large aspect ratio was transformed into measurement of the unidirectional deformation of local characteristic points, and the calibration coefficient was obtained through the full-scale test, and the cable tension was indirectly calculated. The feasibility and accuracy of the monitoring method were verified by comparing the test data with the finite element calculation results. Through simulation analysis and experimental calibration, it was shown that there was a linear relationship between the deformation of the characteristic points of pulley shaft and the cable tension. The cable tension calibration coefficient could be fitted linearly in segments with the cable tension of 280 kN as the boundary. The coefficients of measuring point 1 were 0.312 4 and 0.137 6, and the coefficients of measuring point 2 are 0.269 9 and 0.098 2. The technology and device established in this work can accurately monitor the real-time tension of mooring cables of marine equipment, and have the characteristics of high reliability, low cost and easy operation. |
