摘要

船舶操纵模拟器是内河航道设计和船长培训的重要工具。机动预测的真实感是成功的关键因素。本文建立了一个6自由度机动模型,该模型能够预测不同刚性连接构型(驳船数量、驳船吃水和推力器位置)和不同水深条件下推力船的机动行为。通过自保模型试验确定了该机动模型的各项系数,并通过若干快速仿真运行,包括采用舵、螺旋桨不耦合控制的车队原地转弯,验证了该机动模型的真实性。在有经验的船长的实时模拟运行中进行最终验证。内河船舶的机动预测知识是决定航道通航性的关键因素,特别是当其水深有限(浅水)时。数学模型的质量和准确性需要不断提高。在浅水区作业的推式车队被大量用于执行长途旅行或复杂的机动,如从河流转向港口,现场转向和后退航行。要对其机动能力进行适当的建模,需要一个能够在四个象限(正倒车运动,结合正倒车推进)中运行的数学模型。在文献中,处理为这种类型的内河船舶建立可靠的数学模型及其应用的论文相当稀少。

Maneuvring Behavior of Push Convoys in Different Barge Configurations
Ship maneuvring simulators are a useful tool for the design of inland waterways and for training of skippers. The realism of the maneuvring prediction is a key success factor. In this paper, a 6 DOF (degrees of freedom) maneuvring model is presented which is able to predict the maneuvring behavior of push convoys in different, rigidly connected configurations (number of barges, draft of the barges, and position of the pusher) and for different water depths. The coefficients of this maneuvring model have been determined based on captive model tests and the realism is exemplified with a number of fast time simulation runs, including the turning on the spot of a convoy by means of uncoupled control of rudders and propellers. Final validations were performed during real-time simulation runs with experienced skippers. Knowledge on the maneuvring prediction of inland vessels is a key factor to determine the navigability of the waterways, especially when their water depth is limited (shallow water). The quality and accuracy of mathematical models require a continuous improvement. Push convoys operating in shallow water are intensively used performing long trips or elaborated maneuvers such as turning from a river into a harbor, turning on the spot, and astern sailing. An appropriate modeling of their maneuvring capacity requires a mathematical model able to operate in four quadrants (ahead or astern motion, combined with ahead or astern propulsion). In literature, papers which deal with the creation of reliable mathematical models for this type of inland vessels and their applications are rather scarce.

期刊介绍: Original and Timely technical papers addressing problems of shipyard techniques and production of merchant and naval ships appear in this quarterly publication. Since its inception, the Journal of Ship Production and Design (formerly the Journal of Ship Production) has been a forum for peer-reviewed, professionally edited papers from academic and industry sources. As such, it has influenced the worldwide development of ship production engineering as a fully qualified professional discipline. The expanded scope seeks papers in additional areas, specifically ship design, including design for production, plus other marine technology topics, such as ship operations, shipping economic, and safety. Each issue contains a well-rounded selection of technical papers relevant to marine professionals.
