Ice engineering tests have been conducted in ice bank laboratories for decades, the first ice engineering tests started with the research of icebreakers, the first low temperature ice bank laboratory in the world was soviet-integrated in 1955, and the second ice bank was built in 1969 by finland. The development of an ice engineering laboratory in the initial stage is very slow, the scale is small, the level is low, the developable test content is less, the sailing performance of ships in ice in an ice area is mainly concerned, and a test method and a model ice manufacturing method are not unified. After the 20 th century and the 80 th century, with the rise of marine oil development activities in cold sea areas, the marine development activities are continuously expanded to the cold sea areas, the demands of ships and marine engineering equipment in ice regions are gradually increased, and a large number of low-temperature ice engineering laboratories appear.

However, as the size of ice water pools increases, so does the number of test channels that ice water pools can perform during a freezing process. When the length of the ice water pool is short and the width of the ice water pool is narrow, the ship model can only carry out a test of one channel. And after the channel is used, the next freezing process is required, so that the test of the next channel is convenient to carry out. When the experiment is carried out in the ice water pool with the narrow width, the two ends of the ice layer are connected with the pool wall to limit the movement of the ice layer, and even if the ship model generates thrust to the ice layer when sailing by breaking ice, the ice layer can not slide due to the limitation of the pool wall. Nowadays, the ice water pool is longer in length and larger in width, and a plurality of navigation channels can be opened up simultaneously for testing. However, when the ship model is used for the ice breaking test, after one channel is opened, one side of the remaining flat ice is connected with the pool wall, and the other side of the remaining flat ice is not limited by the pool wall or other ice layers, so that the ice layers are easy to slide when the ship model is used for the ice breaking test.
