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.

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.

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.

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.

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.

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.
