    Abstract
  • In order to study the energy conversion relations in the process of collision between ship and the flexible floating collision-prevention system (FFCPS), the influence of elastic modulus of connecting cable chain on energy dissipation was analyzed.Based on the basic principle of energy conservation, reasonable assumptions were made on the simulation conditions of numerical calculation, and the movement process of flexible floating collision-prevention system was simulated when the system was hit by ship.Under different elastic moduli of connecting cable chain, the changing rules of moving distances of gravity anchors were analyzed.2 kinds of mathematical models were established based on the principle of similarity in displacement and equality in energy, and the numerical calculation results were compared with the experiment results.Analysis result indicates that the elastic moduli of connecting cable chain measure the deformation degree of cable chain, and it is an important influencing factor in the conversion between ship kinetic energy and elastic potential energy.Under the same conditions, the bigger the elastic modulus of connecting cable chain is, the harder the deformation of connecting cable chain is, the less the energy that ship kinetic energy converts into elastic potential energy is, themore the energy that ship kinetic energy converts into friction energy is, and the longer the moving distance of gravity anchor is.Through the comparison between numerical calculation results and experiment results, the suitable value of elastic modulus of connecting cable chain in model test is 260 GPa.To be sure that the connecting cable chain cannot be broken, the selection of cable chain directly affectes the moving distance of system anchor, thus affects the arresting effect of flexible floating collision-prevention system.
