| The development of modern materials science to promote a change in ship manufacturing to new material, Ship manufacturing by composite material has become a trend. Based on the advantage of higher specific stiffness, corrosion resistance, nonmagnetic and molding entirely, glass fiber reinforced plastics (GFRP) is becoming more and more attention in ship application. To ensure the ship had been able to maintain a strong blast, when the vitality of this paper to GFRP for structural lectotype, and then Compartment model for the selected type of experimental analysis, the final adoption of the dynamic response results obtained Ship impact of the anti-explosion capabilities.The hull in different form has a direct impact on the hull structure and performance. In this paper, five kinds of hull structural forms, namely: transverse framing system, longitudinal framing system, combined framing system, hardshell type and sandwich type are numerical analyzed under the conditions of equal load and same quality. It's taken into account the wave load and explosive load during the lectotype process of hull structure.First, analysis takes into account the wave load, and carried out the quasi-static treatment. With energy principle, momentum principle and D'Alembert principle, using the equivalent static method, the explosive load is equivalent to static load to analyze the response and performance of the hull under underwater explosion. Respectively, by calculating and comprehensive performance comparison under wave load and explosive load, one structural form will be selected not only to satisfy structural performance, but also to meet the requirement. Finally, to confirm the best composite material hull structure under wave loads and explosive load.By comparison of Response to numerical analysis and results, hardshell type is the final determining the hull structure. In order to save research time and research costs, it's effective to use compartment model in place with the entire ship model for simulating in ship design. Hence, underwater explosion as basis theory in this paper, it's carrying through non-linear analyzing of composite material compartment model under underwater explosion, and providing numerical analysis reference for compartment design. |
