Abstract

Ships are prone to localized structural damage under the adsorption of automatic mooring equipment. In order to reduce the damage of the ship structure during adsorption, a finite element model of the ship adsorption area should be established to analyze the structural strength and dynamic response of the ship adsorption area during the design of the ship. Apply the adsorption load to the ship adsorption part structure model and design three working conditions to dynamically simulate the adsorption process of the ship of the automatic mooring equipment. The structural strength and dynamic response of the ship during the adsorption process are analyzed. The results show that according to the maximum relative deformation and ultimate strength, the ship strength is ranked from low to high, and it is concluded that when the ship is adsorbed at berth, the more the ratio of the ship plate dimensions in the direction of the length and width tends to be equal, the better the stress is; the more intensively the reinforcement of the ship plate is, the better the stress is. Characteristics of adsorption change: when the ship structure comes into contact with the automatic mooring equipment, the collision force starts to rise rapidly and reaches the peak, which makes the ship structure undergo the maximum deformation, and then the force and deformation of the ship structure tends to stabilize and tends to a fixed value.
