近年來(lái)，大規?；蛉叽绲淖酝七M(jìn)仿真引起了人們廣泛的興趣。然而，這些數值模擬往往缺乏物理試驗的驗證。因此，可靠和有效的大規?；蛉叽缒Ｐ驮囼烇@得尤為重要。因此，自然環(huán)境下的大型模型試驗技術(shù)得到了足夠的重視和顯著(zhù)的發(fā)展。大型艦船模型試驗主要包括三個(gè)方面：螺旋槳的結構載荷與響應、波浪作用下的運動(dòng)和推進(jìn)性能。

In recent years, large-scale or full-scale self-propelled simulation has attracted extensive interest. However, these numerical simulations often lack the verification of physical experiments. Therefore, reliable and effective large-scale or full-scale model tests are particularly important. Therefore, the large-scale model test technology in the natural environment has received sufficient attention and significant development. The large-scale ship model test mainly includes three aspects: structural load and response of propeller, motion and propulsion performance under wave action.

艦船模型試驗系統的設計是一個(gè)復雜的過(guò)程，是保證試驗成功的關(guān)鍵。大型模型試驗系統可分為控制系統、數據測量與采集系統和GPS/INS組合導航系統三部分。

The design of ship model test system is a complex process, and it is the key to ensure the success of the test. The large-scale model test system can be divided into three parts: control system, data measurement and acquisition system and GPS / INS integrated navigation system.

模型控制系統是艦船模型驅動(dòng)的核心，主要包括上位機、從機、兩個(gè)螺旋槳和舵機伺服電機。主機發(fā)出控制命令，使用Windows7操作系統，控制軟件使用VisualBasic編寫(xiě)。

The model control system is the core of the ship model drive, mainly including the upper computer, the slave computer, the two propellers and the servo motor of the steering gear. The host sends out control commands, using Windows 7 operating system, and the control software is written in Visual Basic.

用戶(hù)控制界面顯示舵角、轉數等各種參數，也可以通過(guò)控制界面輸入參數來(lái)改變船模的運動(dòng)。從機接收到上位機發(fā)出的指令，將其轉換為實(shí)時(shí)信號，直接控制螺旋槳控制電機和方向舵控制電機。下位機讀取伺服電機的狀態(tài)數據，將其轉換為數字信號反饋給上位機。

The user control interface displays various parameters such as rudder angle and rotation number, and can also input parameters through the control interface to change the motion of the ship model. The slave computer receives the instructions from the upper computer, converts them into real-time signals, and directly controls the propeller control motor and the rudder control motor. The lower computer reads the state data of the servo motor, converts it into a digital signal and feeds it back to the upper computer.

在本次試驗中，自主研制了一臺儀器來(lái)準確測量螺旋槳產(chǎn)生的推力和扭矩。一個(gè)32位通道的商業(yè)數據收集器被用來(lái)把測量的電信號轉換成數字信號，然后傳輸到一臺筆記本電腦上。采用動(dòng)態(tài)信號分析軟件對數據進(jìn)行實(shí)時(shí)記錄和分析。

In this test, we independently developed an instrument to accurately measure the thrust and torque generated by the propeller. A 32-bit channel commercial data collector is used to convert the measured electrical signals into digital signals, which are then transmitted to a notebook computer. The dynamic signal analysis software is used to record and analyze the data in real time.

該模型使用了非遙感控制。船上少需要兩名人員進(jìn)行測試工作：一人負責駕駛，另一人負責數據收集。該數據測量與采集系統由三個(gè)加速度傳感器、一臺自行研制的儀器、一個(gè)數據采集器和一臺筆記本電腦組成。測量的參數包括船體的垂直加速度、螺旋槳的推力和扭矩。采用加速度傳感器測量船體的深沉運動(dòng)，對加速度曲線(xiàn)進(jìn)行二次積分，可以得到船體的升沉運動(dòng)曲線(xiàn)。

The model uses non remote sensing control. At least two personnel are required on board to carry out the test: one is responsible for driving and the other is responsible for data collection. The data measurement and acquisition system consists of three acceleration sensors, a self-developed instrument, a data collector and a notebook computer. The measured parameters include the vertical acceleration of the hull, the thrust and torque of the propeller. The heave motion curve of the hull can be obtained by measuring the heave motion of the hull with an acceleration sensor and integrating the acceleration curve twice.
