【摘要】：在内河限制航道中,由于水深受限,同时受到风、流和岸壁效应的作用,导致了船舶的运动状态与无限水域中有很大不同。为了提高人民的生命和财产安全,预防船舶的碰撞,搁浅以及其它影响船舶航行安全的情况。通过仿真能够帮助船员预测一些紧急情况。因此对内河限制航道客船操纵运动的仿真是非常有必要的。本文通过建立了限制航道的客船操纵运动数学模型,在数学模型的基础上以内河客船“世纪神话”的相关数据为参考,对“世纪神话”在内河限制航道中的多种运动情况进行了仿真。首先,本文是采取的日本数学模型小组的方法,分别考虑船,桨,舵各部分的作用力,然后考虑了它们相互之间的一些干涉作用。在深水船舶运动数学模型的基础上,乘上浅水修正系数,将深水模型转化为浅水模型。同时对船舶的大小不同漂角采用不同的计算方式,来保证船舶运动的连续性。考虑到内河风流的影响在浅水模型的基础上加入风和流的数学模型。最后因为岸壁效应的影响,在上述模型的基础上加入岸壁效应作用力和作用力矩。在本文建立了完善的数学运动模型后,采用了四阶的龙格-库塔法对船舶操纵运动方程进行数值的求解。并且建立船舶任意时刻运动的位置和其余相关参数的确定方程。对模型求解后,本文利用C++编程语言,对船舶在受限水域的回转性能以及相关的一些操纵运动进行了仿真。尤其是对船舶在不同航道,不同水深,不同航速情况下,船舶受岸壁的作用力的影响分别进行了仿真。就仿真的相关结果,本文得出一系列的结论,所得结论与前辈们的理论分析相吻合,也论证了该仿真结果的正确性。本文通过相关研究得出客船在内河限制航道航行的时候,它的旋回性能与深水中有较大差异,同时由于离岸距离不同,航行速度不同,水深与吃水比不同,它所受的岸壁效应的影响也不一样。这一结果对预防海事事故以及内河船员掌握在限制航道航行时船舶的操纵性有很大的参考价值,同时对于学生学习和了解内河限制航道里复杂的航行情况有很大的帮助。本文对于开发完整的船舶模拟器也有一定的理论参考价值。
[Abstract]:In the limit of inland waterway, due to limited water depth at the same time, by the wind, flow and wall effect, lead to big different motion state of ship and the infinite water. In order to improve people's lives and property safety, ship collision prevention, stranding and other effects of ship navigation safety. The simulation can help the crew prediction of some emergency. So it is very necessary for the simulation of inland waterway ship maneuvering limit maneuvering model. In this paper, through the establishment of limited waterway passenger ships, based on the mathematical model based on the data of inland passenger ships "century myth" as a reference to the "Century myth" was simulated in the inland limit a variety of movement of the channel. First of all, this paper is method of mathematical model of the Japanese team, considering the ship, propeller, rudder force of each part, and then test Considering the interaction between them. Based on some deep water ship motion mathematical model, a shallow water correction coefficient, the model is transformed into a deep shallow water model. At the same time, the size of the ship at different drift angle is calculated by using different methods, to ensure the continuity of ship motion mathematical model. Considering the influence of the inland air based on shallow water model with wind and current. Finally, because of the impact of bank effect, and the effect of adding bank effect force moment on the basis of the above model. In this paper the mathematical model established, solved using the Runge Kutta method of order four on the ship maneuvering motion equations numerically. To determine the position of the movement equation of ships at any time and other relevant parameters and established. To solve the model, using the C++ programming language, the performance of ships in restricted waters to turn And some related maneuvering motion simulation. Especially the ship in different channel, different depth, different speed, impact force of the ship by the quay are simulated. The simulation results, this paper draws a series of conclusions, the conclusion of theoretical analysis and the predecessors of the match, right it proves that the simulation results. This paper studies in the Inland Waterway Navigation passenger restrictions, different cycle performance and its deep water, at the same time as the distance from the shore, sailing speed, water depth and draft ratio, influence it by bank effect is not the same as the results. On the prevention of maritime accidents and inland crew master has great reference value for handling ships in restricted water navigation, at the same time for students to learn and understand the complex navigation in inland waterway limits It is of great help to the situation. This paper also has a certain theoretical reference value for the development of a complete ship simulator.
