【摘要】：隨著船舶設計和推進技術的發(fā)展,現代水面艦船推進器越來越多地采用雙調距槳雙舵推進,對于該類艦船的操縱和推進性能研究是具有理論和實用意義的重要問題。本文研究了雙調距槳雙舵艦船操縱運動模型的建立和操縱性能優(yōu)化問題,應用虛擬現實技術,實現了雙調距槳船舶運動的虛擬現實仿真,直觀地展現了所建立的艦船模型的操縱運動性能。本文完成的主要研究工作如下：(1)本文根據某算例船型數據建立了雙調距槳雙舵船舶的MMG操縱運動模型,分別建立了作用于裸船體、槳和舵上的流體動力和力矩數學模型,用所建的模型進行了操縱性能仿真試驗。(2)在所建模型的基礎上,利用粒子群優(yōu)化算法對雙調距槳船舶操縱性能和推進器負荷進行優(yōu)化,旨在改善船舶的旋回性能和調距裝置的可靠性,論文具體分析了船舶作旋回運動時旋回圈特性參數值和內外槳負荷值的變化。(3)實現了雙調距槳船舶運動和推進器傳動機構的數字仿真和虛擬現實仿真,數字仿真部分利用Matlab/Simulink計算船舶運動模型的信息,包括船舶位姿、航速、航向角等,同時把數值信息實時體現在視景界面的船舶模型中；虛擬現實仿真部分通過Vega API獲取船舶運動參數建立了基于Vega平臺的船舶運動虛擬仿真系統(tǒng),實現了船舶操縱視景仿真同時將在3D max中建立的模型在Creator中進行優(yōu)化,利用DOF節(jié)點構建了動態(tài)模型,實現槳轂工作原理三維實時動畫演示功能。
[Abstract]:With the development of ship design and propulsion technology, modern ship propeller adopts more dual propeller twin rudder ship propulsion, for this kind of manipulation and Research on propulsion performance is an important problem that has theoretical and practical significance. The establishment and manipulation of performance optimization this paper studies the problem of dual propeller twin rudder ship maneuvering motion model the application of virtual reality technology, virtual reality simulation of the dual propeller of ship motion, displayed the model of ship maneuvering motion performance. The main research work of this paper are as follows: (1) based on a kinematic model of ship data to establish a dual propeller twin rudder ship MMG control, were established on bare hull, the hydrodynamic force and torque mathematical model of propeller and rudder on, with the model of operating performance test. (2) based on the model , using particle swarm optimization algorithm of dual propeller ship maneuverability and propeller load optimization, reliability to improve the ship performance and cycle distance adjusting device, this paper analyzes the ship turning movement when turning circle parameters change and external load value. The paddle (3) digital simulation and virtual reality simulation of the dual propeller ship and propeller drive, digital simulation using Matlab/Simulink calculation model of ship motion information, including the ship position, speed, heading angle, while the numerical information in real time reflected in the ship model visual interface; virtual reality simulation by Vega API to obtain the ship motion parameters a ship motion virtual simulation system based on Vega platform, realizes the ship maneuvering as Jing Fangzhen also will be built on the 3D Max model optimized in Creator, The dynamic model of the DOF node is constructed to realize the 3D real-time animation demonstration function of the working principle of the wheel hub.
