摘要
针对某典型SPAR平台湿拖状态下的阻力特性进行研究。在低傅汝德数条件下对模型进行拖航试验,详细分析了SPAR模型湿拖过程中的阻力成分,由于SPAR阻力与常规船型不同,首先提出摩擦面积的概念,通过阻力换算,估算SPAR实际拖航过程中阻力大小,并对试验模型剰余阻力数据进行曲线拟合,提出对SPAR阻力的近似估算方法。
The research is mainly about resistance characteristic during the SPAR wet towing. The experiment was organized in low speed in order to analyze the resistance composition in SPAR wet towing. After resistance conversion, the real SPAR towing resistance can be obtained. This paper also include a regression formula of the residual resistance of SPAR wet towing using the method of the least squares, which provides guarantee for the SPAR construction effectively.
