تحلیل عددی اثرات توزیع فشار هیدرودینامیکی بر روی شناور تندرو کامپوزیتی و بهینه‌سازی سازه شناور

In this research, hydrodynamic distribution pressure in continuous times is done and stress and displacement of a high speed vessel are studied. Hydrodynamic distribution pressure is studied for different dead rise angle according to vertical and horizontal vessel velocity at dry chine and wet time steps and is applied to vessel at continues times of vessel variable position. Vessel body is divided to some parts according to different dead rise angles and loading is applied as incremental loading. Shell of composite vessel is modeled using ABAQUES commercial finite element software as layer to study the effect of ever layer in stacking sequences, then change of the core thickness and optimization of vessel structure is studied that causing safety factor is increased and weight is decreased. At the end, results of critical stress and maximum displacement of different parts of vessel is compared and evaluated in initial and optimized vessel.
