摘要
大型船舶在设计航速下的操纵性通常不佳,导致船舶安全航行不断面临风险挑战。与此同时,在船舶智能化、无人化不断发展的今天,大型船舶的先天操纵性不佳问题也对实现安全的船舶自主操控提出了更为严苛的技术要求。为了提升现有船舶的减速性能,文章提出了一种减速鳍装置,基于实尺度计算流体动力学(CFD)绕流阻力分析研究其减速性能,并对其减速效果进行仿真。研究表明,配备设计得当的减速鳍,可明显提升大型船舶的减速及转艏性能,从而大幅改善船舶操纵性及航行安全性。
The manoeuvrability of large ships is generally undesirable at their design speed,resulting in continuous risks to ship navigation safety.Meanwhile,the development of intelligent and unmanned ship design and construction brings stricter technical requirements for the safe realisation of autonomous ship navigation due to the inherent weakness in the manoeuvrability of large ships.To improve the braking performance of existing ships,the study proposes the installation of a pair of spoiler fins,the braking performance of which is investigated using real-scale CFD flow resistance analyses.Furthermore,the braking effects are simulated.The study shows that equipping large ships with properly designed spoiler fins can significantly improve their deceleration and steering performance,thereby promoting higher ship manoeuvrability and navigation safety.
