高耐波性排水型单体复合船型试验研究

以某一常规单体圆舭船型为母型,研究开发了一高耐波性单体复合型。选取三个单体复合船型方案模型进行了静水阻力、规则波及不规则波试验。分析了构成复合船型的组合附体的线型、尺度与安装位置对阻力和耐波性的影响,优选出一耐波性优良的复合船型。试验结果表明,所开发的单体复合船型可显著抑制舰船的纵向运动,具有合理的线型、尺度和布局的组合附体所形成的单体复合船型,对原船的静水阻力影响不大。该船型的开发对大幅提升常规单体排水型舰船的耐波性具有较大实用价值。

The Test Research on High Seakeeping Performance Displacement Hybrid Monohull Ship

The model tests of a hybrid monohull ship which is designed on basis of conventional rounded chine monohull ship are carried out.There is a stabilizing appendage on the bottom of the stem of the ship which consists of a semi-submerged hull and passive bow-fin.Three appendage schemes are selected.The purpose of the tests is to analyze the affect of the appendage on resistance and seakeeping of the ship and to find the optimal scheme.The test results show that the longitudinal motions of the hybrid monohull ship are reduced considerably compared with the conventional rounded chine monohull ship,and the resistance is the same nearly as one of the conventional rouded chine ship.
