Molded Lines Optimization Design of High-Speed Passenger Ship Based on Full Parameterization Modeling

以某型高速客船为研究对象。采用CAESES FRIENDSHIP-Framework软件进行全参数化建模,对初始模型采用SHIPFLOW软件进行兴波阻力计算,将计算结果与船模试验结果进行对比,以验证计算的可靠性。采用Sobol算法进行特征参数的灵敏度计算,以有效降低设计空间维数,提高计算效率。建立多航速优化模型,完成船体艏部兴波阻力优化。结果表明,优化模型的兴波阻力在多航速下较初始模型均明显降低,研究结果具有一定的工程实用价值。

A type of high-speed passenger ship is taken as the research object.The CAESES FRIENDSHIP-Framework software is used to make the full parameterization modeling,the SHIPFLOW software is used to calculate the wave-making resistance of original model,and the calculated results are compared with the ship model test results to verify the calculation reliability.The Sobol algorithm is used to calculate the sensitivity of characteristic parameters to effectively reduce the design space dimensions and improve the calculation efficiency.A multiple speed optimization model is established to complete the wave-making resistance optimization of hull bow.The results show that the wave-making resistance of optimization model is significantly lower than that of original model at multiple speeds,and the research results are of certain practical value in the engineering.
