摘要
为获得阻力性能优良的船型,以某深拖母船作为母型船,运用参数化建模技术在优化平台Friendship中建立参数化模型,以兴波阻力作为优化目标,先运用全局搜索Sobol算法进行初步优化,再运用局部搜索Tsearch算法进行二次优化,结果显示,优化船型的兴波阻力较母型船明显降低,优化效果良好。将优化结果与CFD软件STAR-CCM+的计算结果以及母型船模型试验结果对比表明,基于兴波阻力的船型优化对于总阻力有一定的降阻效果。
To search for minimum wave-making resistance hull form,a deep-towing system mother-ship was used as parent model and rebuilt into a parametric model.With the wave-making resistance as the optimization target,the Sobol algorithm was used for the initial optimization,followed by the local Tsearch algorithm for the secondary optimization.The results showed that the wave-making resistance of the optimized ship is obviously lower than that of the parent ship.Comparing the optimization results with that of CFD software STAR-CCM+and the result of model test of the parent model,showing that the hull optimization based on wave-making resistance can reduce the total resistance to a certain extent.
