AI Technical Summary

Problems solved by technology

[0003] The impact resistance test of ship structures under calm water and the structural fatigue strength and stability tests have been fully studied by scholars at home and abroad, but the working condition tests in different sea area wave environments have not been fully studied, mainly because the waves in different sea areas Various forms and the simulated wave environment have high requirements for the test site, and it is difficult to achieve high-quality waves

[0004] At present, there are roughly three types of test methods in different wave environments at home and abroad. The first method is to expand the test site. The test site is larger and the active wave-making device creates ideal waves. In the process of motion transmission, energy is consumed, and a passive wave-absorbing area is set at the edge of the test site to eliminate wave reflection. This method has great limitations, requires a large test site, is expensive and has low accuracy.

The second method is a small wave-making tank, which creates waves in one direction. A small passive wave breaker is installed on the other side of the wave-making tank device. This method has poor wave elimination ability and cannot eliminate reflected waves in real time. Test the wave quality Difference

The third method is to actively compensate the wave-making tank. Actively create waves on one side of the wave-making tank, install a wave height measuring instrument in front of the wave-making device in the tank, and feed back the wave records reflected by the boundary to the active wave-making system. The returned wave information actively compensates the wave size, so that the target wave remains unchanged, and actively eliminates the reflected wave. This method is difficult to implement, and it cannot achieve high precision and high quality of the target wave.
