Abstract

The invention provides a measurement system and measurement method utilizing non-freezing model ice to obtain the ship model resistance in trash ice. First, by selecting non-freezing model ice from a conventional towing pool to replace frozen model ice in an ice pool, so that the towing pool without a low temperature environment is equipped with the condition of simulating ice trash working conditions; and then a unique buoy fence structure is designed on the surface of the towing pool to achieve simulation of an ice trash channel, and a force cell is used to realize measurement of the ship model resistance at different speeds. In addition, the invention adopts the means of firstly measuring the resistance of the open water and measuring the resistance at a very low speed (0.02m/s) under the floating ice condition, elements such as the open water resistance, the floating ice resistance and the clear ice resistance are separated, and the resistance performance of a corresponding ship model and a real boat in the working condition of trash ice is forecast. The measurement system and measurement method of the invention provides a new idea for measurement of the ship model resistance in the trash ice in a condition that now ice pool facilities in china are not perfect.

Description

technical field [0001] The invention relates to a measurement system and a measurement method for obtaining the resistance of a ship model in crushed ice by using non-freezing model ice, and belongs to the technical field of experimental measurement. Background technique [0002] With the warming of the global climate, the Arctic glaciers are gradually melting, which provides the possibility for the opening of the Arctic waterway and the development of the rich resources of the Arctic, and the games around the Arctic region are intensifying among countries around the world. Ships in the polar ice region are important equipment and carriers for resource exploration, development, transportation and scientific research in the Arctic region with low temperature, ice and extremely harsh climate, and will definitely play a central role. Therefore, countries around the world have increased the design and construction of ships in ice regions to expand their influence in the Arctic r...
