摘要
针对提出的深V单体复合船型从理论预报与模型试验研究其纵向运动性能。理论预报采用STF法,在水动力计算中加入粘性与航态修正;在船模拖曳水池进行耐波性试验。理论计算与模型试验结果表明:考虑粘性与航态修正的STF法能够较好地预报深V单体复合船型的纵向运动性能,满足工程精度要求;深V船型耐波性比常规圆舭船型较优,加装减纵摇组合附体后其纵向运动性能进一步得到大幅提高。
The longitudinal motion performance of a deep-V mono--hull was researched. STF method with modification of viscous and bow up state was used for theory prediction, and model test for sea-keeping performance was done in towing tank. The theoretical results indicated that method proposed can get the satisfactory result for longitudinal motion, and it meets the request of engineering precision. And the model test results showed that the sea-keeping performance of deep-V ship is better than round bilge ship, and it is much better after installing the built-up stabilizing append- age.
