Finally, according to different test objects and test requirements, different test instruments and sensors are installed in the device box structure 532 to complete the test task.

[0081] like Fig. 22As shown in the figure, in practice, the wave-making of ships is caused by the different changes in the water pressure around the hull along the length of the ship when the ship is sailing. The changes in the pressure around the hull and the distribution along the length of the ship are closely related to the ship type, ship speed, ratio of water depth to draft, etc., and the wave-making caused by high-speed ships (the channel boat 100 belongs to a high-speed ship) is more serious. During the high-speed ship towing test in open waters, two high-speed channel boats 100 will generate huge waves, which will have a huge impact on the test data and results of the model, so measures must be taken to reduce the adverse effects of wave-making on the test; on this basis, such as Fig.23 As shown, a blocking and isolating method is adopted, that is, two wave-breaking blade-shaped plate devices 400 are arranged on the inner side of two channel boats 100. The blade-shaped plate 411 of the device is shaped like a long and thin knife. When it comes into direct contact with the waves, it directly cuts the waves, making it have strong wave resistance. At the same time, the wave-making and wave-making resistance generated are small, and the impact on the test data and results of the model 539 is very small. The most important thing is that the blade-shaped plate 411 is like a wall, blocking the wave-making generated by the channel boat 100 and diverting it to the rear, which will not have any impact on the model at all. At the same time, circular hole-shaped wave-breaking holes 412 are evenly distributed under the blade-shaped plate 411. When the wave water flows through the wave-breaking holes 412, a certain amount of energy consumption will be generated, thereby achieving the effect of further eliminating the wave-making generated by the channel boat body 101.

[0082] like Figure 24 to Figure 27 As shown in the figure, in practice, conventional water tanks use the roll restoring moment generated by the different liquid levels of the water tanks on the left and right sides of the single hull to offset the wave disturbance moment; Fig.25 and Fig. 27 As shown, the device of the present invention is composed of two left and right channel boat bodies 101. Therefore, in terms of roll, the anti-roll water tank 110 uses the roll restoring moment generated by the different liquid level heights of the left and right hull water tanks to offset the transverse wave disturbance moment, and in terms of pitch, the anti-roll water tank 110 uses the pitch restoring moment generated by the different liquid level heights of the front and rear water tanks of the single hull to offset the longitudinal wave disturbance moment. The anti-roll water tank 110 of the present invention is suitable for the low-speed navigation state of the ship, and adopts active control, that is, relying on the angular velocity gyro installed on the hull to sense the roll angular velocity signal or pitch angular velocity signal of the ship, and adopts a servo control valve to control the water volume of the entire front, rear, left and right anti-roll water tanks 110 to establish a stable counter torque of the test device, ensuring the smooth navigation of the high-speed ship towing test.

[0083] like Figure 28 to Figure 31As shown, in practice, conventional anti-roll fins are generally installed on the bilges on both sides of the ship, and the cross-section is symmetrical wing-shaped. The anti-roll fins are rotated by the operating mechanism to make the water flow produce an upward or downward force to form a damping force to reduce the roll of the ship. The anti-roll effect of the anti-roll fin depends on the speed. The higher the speed, the better the effect. The device of the present invention symmetrically installs four anti-roll fins (left rear fin 121, right rear fin 122, left front fin 124 and right front fin 125) on the left and right channel boat hulls 101. In terms of roll, the present invention adopts an adjustment method in which the anti-roll fins on the left hull and the anti-roll fins on the right hull rotate in opposite directions, and one side of the hull generates upward hydrodynamic lift and the other side generates downward hydrodynamic pressure to form a roll restoring moment to offset the lateral wave disturbance moment. In terms of pitching, the fins on the front hull and the fins on the rear hull rotate in opposite directions, forming different hydrodynamic lifts or hydrodynamic pressures in front and behind to generate pitching restoring moments, thereby achieving the purpose of offsetting the longitudinal wave disturbance moment. Therefore, the fins 120 in the present invention are applied to the high-speed navigation state of the ship, and an active control system is also adopted, relying on the angular velocity gyro installed on the hull to sense the roll angular velocity signal or pitch angular velocity signal of the ship, and using a servo control valve or a servo motor to control the hydraulic drive and the electric drive to achieve the forward and reverse rotation of the fins 120, establish a stable counter torque of the test device, and ensure the smooth navigation of the high-speed ship towing test.

[0084] The present invention adopts a unique frame connection structure to construct a double-channel boat high-speed towing test vessel that meets the requirements of open water tests; at the same time, the present invention also actively controls the channel boat body 101 equipped with a roll-reducing fin 120 and a roll-reducing water tank 110, establishes a stable counter-torque of the test device, and ensures smooth navigation of the high-speed boat towing test; finally, the present invention specifically sets up a wave-breaking blade plate device 400, which solves the problem of the influence of the wave-making generated by the channel boat body 101 on the test data and results of the model 539.
