Experimental mechanical study of ship structure during automatic mooring operation

In order to ensure the safety and reliability of the strength of the ship structure which is adsorbed during the automatic mooring operation, resistive strain gauges and an online strain monitoring system are arranged in the places where the stress of the ship structure is concentrated, so that the stress and deformation of the ship structure can be monitored and analyzed. The locations of the maximum values of stress and deformation of the ship structure are determined by the finite element method, and these locations are selected as the place of the resistive strain gauges. The measured values of the ship structure are obtained through the strain online monitoring system and compared with the results of the finite element calculation. Comparative analysis of the strain theoretical calculation results and test results of the ship structure shows that the theoretical data are in good consistency with the experimental data, which proves the correctness and effectiveness of the online strain monitoring system for the ship structure.
