摘　　要：结合新型中型海洋救助船的功能需求和主尺度特点,对其快速性特征进行分析。运用CFD方法,首先对初始方案的线型进行静水阻力计算,然后根据流场信息,分别对球鼻艏、前体线型以及分水踵进行优化,得到了最终方案,阻力比较初始方案有了大幅降低。将最终方案进行模型试验,模型试验结果与CFD计算结果吻合良好,证明了优化过程的正确性以及最终方案阻力性能的优秀。Based on the functional requirement and main dimensions, analysis of speed performance is carried out for a new medium-size salvage vessel. By using CFD method, resistance in calm water for the initial hull form is calculated, which provides information about the flow field for further optimization. Then the hull body including bulbous bow, forebody and skeg is optimized, and a final hull form with a dramatic reduction in resistance is obtained. Results of model test agree well with that of CFD for the final hull form, and it is shown that the optimal process is reasonable and the final hull form is excellent in resistance performance.
