摘要
PCTC(车辆运输船)作为一种中高速船,其兴波阻力在阻力成分中的占比较高。采用非线性兴波数值计算手段以及半参数化方法对一条PCTC进行了线型优化设计。通过多轮计算,最终获得一个优化线型。在此基础上,开展了模型试验验证。试验结果表明,优化线型方案的总阻力系数下降约2%。
In order to carry out lines optimization for a PCTC, nonlinear wave-making numerical method and partial parametric method of lines are adopted. An optimized hull is obtained with this method. Corresponding model test indicates that about 2% reduction of total resistance can be achieved for the optimized lines in comparison with the prototype.
