摘要
本文根据降阻机理对压浪线型作了有益的探索和重点研究 ,开发了组合式新船型 ,并提出了两个新概念 :带分水踵船型的波形认为是主船体和分水踵两者波形的叠加 ;压浪高度随 Fr的变化而变化。通过对比试验 ,取得在 Fr=0 .32设计航速时 ,新船型比原船阻力降低 16 %的明显效果。此外 ,还对两船型的首底砰击进行理论计算 ,计算结果表明新船型首底砰击力度明显减缓。
The paper presents a study on the wave suppression hull form of the landing ship according to the resistance reduction theory, which results in a new composite type hull form and two new concepts:the wave form of the hull with dividing heel is the superimposition of the wave from hull and wave from heel, and the height of wave suppression varies with the change of Frvalue. Through comparing test, good effect of resistance reduction is verified that the resistance of the new hull form is 16% lower than that of original hull form at design speed with Fr=0.32. In addition, calculation is carried out for fore bottom slamming for two ship types and the results indicate that the slamming force on fore bottom is considerably reduced for the new ship type.
