摘 要: 阐述了动力定位推进系统中螺旋桨之间干扰的研究方法及研究进展,重点介绍了目前国内外关于螺旋桨与螺旋桨干扰的研究方法与成果,集中对有关经验公式进行总结和分析,得出了一系列的结论。有针对性地提出了模型试验及数值试验方法。最后,就如何有效降低螺旋桨-螺旋桨之间的干扰,从而提高动力定位推进系统的推进效率,加强动力定位能力,进行归纳与说明。提出了最优推力分配模块中禁止角边界条件这一概念,这对于解决动力定位推进系统中螺旋桨与螺旋桨之间的水动力干扰具有显著的作用。 This article elaborated on the recent research progress of the interaction mechanism in the dynamic positioning propulsion system. And some research results which are valuable for the engineering were also presented, including some useful empirical equations. Focused on the causes of the interference, this article discussed the mechanism of thruster-thruster interaction, and summarized the methods of how to reduce effectively the effects of hydrodynamic interaction. The main objective of the work is to improve the capability and efficiency of the dynamic positioning propulsion system. Consequently the concept of forbidden angle was presented aiming at improving the hydrodynamic characteristics of the dynamic positioning propulsion system.
