  • 摘要:
      目的  旨在阐述采用吊舱推进船舶在波浪中的功率增加预报试验方法,并通过模型试验得到目标豪华邮轮在实际海域中的功率增加值。
      方法  针对一艘采用吊舱推进的豪华邮轮,在拖曳水池中开展波浪中的自航模型试验研究,通过在缩尺后的吊舱包内安装专为本试验研制的吊舱动力仪,测量吊舱桨发出的扭矩和转速,然后将传统的静水自航试验方法拓展至波浪中,依据ITTC推荐规程对试验数据进行后处理并分析影响试验精度的误差来源。
      结果  根据ITTC推荐的扭矩转速法预报得到的目标船功率增加峰值出现在波浪周期12 s附近,当有义波高为2 m时,波浪中功率增加值为554 kW,占静水中功率的比例达18.53%。
      结论  所述自航模型试验方法适用于吊舱推进船舶,可用于预报船舶在波浪中的功率增加,可为深入研究船舶在波浪中的推进特性,进一步丰富船舶节能减排的设计优化手段提供有益参考。

     

    Abstract:
      Objectives  This paper aims to expand the prediction method of a power increase in waves for ships with podded propulsion, and to predict the power increase of a luxury cruise ship in actual seas through model experimentations.
      Methods  A self-propulsion test for a cruise ship with podded propulsion in waves is performed in the towing tank. A tailor-made dynamometer is installed inside the model scale pod unit for torque and revolution measurement, and the traditional self-propulsion test method in calm water is further developed and applied to the test in waves. Additionally, the experiment data is post-processed according to ITTC recommended procedures, and the error sources was analyzed.
      Results  According to the ITTC torque and revolution method, the obtained peak power increase of the target cruise ship occurs at wave periods close to 12 s; when the significant wave height is 2 m, the power increase in waves is 554 kW, corresponding to 18.53% of the power consumption in calm water.
      Conclusions  The experimental method presented in this paper is applicable for ships with podded propulsion and can be used for the prediction of a power increase in waves. This provides a reference for a more detailed investigation into the ship's propulsion characteristics in waves and can help expand the design optimization approaches towards more energy-efficient ships.
