【摘要】：在內(nèi)河限制航道中,由于水深受限,同時(shí)受到風(fēng)、流和岸壁效應(yīng)的作用,導(dǎo)致了船舶的運(yùn)動(dòng)狀態(tài)與無(wú)限水域中有很大不同。為了提高人民的生命和財(cái)產(chǎn)安全,預(yù)防船舶的碰撞,擱淺以及其它影響船舶航行安全的情況。通過(guò)仿真能夠幫助船員預(yù)測(cè)一些緊急情況。因此對(duì)內(nèi)河限制航道客船操縱運(yùn)動(dòng)的仿真是非常有必要的。本文通過(guò)建立了限制航道的客船操縱運(yùn)動(dòng)數(shù)學(xué)模型,在數(shù)學(xué)模型的基礎(chǔ)上以內(nèi)河客船“世紀(jì)神話”的相關(guān)數(shù)據(jù)為參考,對(duì)“世紀(jì)神話”在內(nèi)河限制航道中的多種運(yùn)動(dòng)情況進(jìn)行了仿真。首先,本文是采取的日本數(shù)學(xué)模型小組的方法,分別考慮船,槳,舵各部分的作用力,然后考慮了它們相互之間的一些干涉作用。在深水船舶運(yùn)動(dòng)數(shù)學(xué)模型的基礎(chǔ)上,乘上淺水修正系數(shù),將深水模型轉(zhuǎn)化為淺水模型。同時(shí)對(duì)船舶的大小不同漂角采用不同的計(jì)算方式,來(lái)保證船舶運(yùn)動(dòng)的連續(xù)性�？紤]到內(nèi)河風(fēng)流的影響在淺水模型的基礎(chǔ)上加入風(fēng)和流的數(shù)學(xué)模型。最后因?yàn)榘侗谛?yīng)的影響,在上述模型的基礎(chǔ)上加入岸壁效應(yīng)作用力和作用力矩。在本文建立了完善的數(shù)學(xué)運(yùn)動(dòng)模型后,采用了四階的龍格-庫(kù)塔法對(duì)船舶操縱運(yùn)動(dòng)方程進(jìn)行數(shù)值的求解。并且建立船舶任意時(shí)刻運(yùn)動(dòng)的位置和其余相關(guān)參數(shù)的確定方程。對(duì)模型求解后,本文利用C++編程語(yǔ)言,對(duì)船舶在受限水域的回轉(zhuǎn)性能以及相關(guān)的一些操縱運(yùn)動(dòng)進(jìn)行了仿真。尤其是對(duì)船舶在不同航道,不同水深,不同航速情況下,船舶受岸壁的作用力的影響分別進(jìn)行了仿真。就仿真的相關(guān)結(jié)果,本文得出一系列的結(jié)論,所得結(jié)論與前輩們的理論分析相吻合,也論證了該仿真結(jié)果的正確性。本文通過(guò)相關(guān)研究得出客船在內(nèi)河限制航道航行的時(shí)候,它的旋回性能與深水中有較大差異,同時(shí)由于離岸距離不同,航行速度不同,水深與吃水比不同,它所受的岸壁效應(yīng)的影響也不一樣。這一結(jié)果對(duì)預(yù)防海事事故以及內(nèi)河船員掌握在限制航道航行時(shí)船舶的操縱性有很大的參考價(jià)值,同時(shí)對(duì)于學(xué)生學(xué)習(xí)和了解內(nèi)河限制航道里復(fù)雜的航行情況有很大的幫助。本文對(duì)于開發(fā)完整的船舶模擬器也有一定的理論參考價(jià)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.
