摘　　要：在航运界节能减排的大背景下,我国内河船面临性能指标落后、缺乏持久竞争力等问题,亟待研发新一代船型。本文通过对影响双尾鳍水动力性能的关键参数组合进行研究,选定一组最佳参数并建立尾部全参数化模型。基于粘势耦合的数值计算方法,采用Sobol优化算法,以阻力和收到功率为优化目标对参考船进行参数优选,并多角度结合数值计算结果得到最终优化方案。经过拖曳水池模型试验,验证了优化线型具有良好的水动力性能。该方法在双尾鳍船型的线型设计阶段具有较高的工程应用价值,为常规双尾鳍内河船的快速设计提供了有效途径。Under the background of energy conservation and emission reduction in the shipping industry,the riverboat in our country,which has a poor performance and a lack of competitiveness,is in an urgent need for a new generation of hull form.In this paper,by studying the combination of key parameters affecting the hydrodynamic performance of twin-skeg ships,a full parametric model of stern form is established based on the best parameters.With the use of viscous and potential coupling numerical method and the sobol optimization algorithm,the optimization of a target hull form is carried out under the goal for low resistance and delivered power.In order to choose the best design,the calculation results are analyzed in different views.The towing tank model test verifies that the optimized hull form has a good hydrodynamic performance.The method has a significant engineering value in the design period of twin-skeg hull forms,which provides a effective way for the quick design of normal twin-skeg riverboats.
