Ice rink distribution and data processing method for ship ice breaking resistance experiment

Abstract

The invention discloses an ice rink distribution and data processing method for a ship ice breaking resistance experiment. Broken ice is evenly distributed in a broken ice region before each ship icebreaking resistance experiment, and the mutually overlapped broken ice is eliminated, so that the working condition is close to the design working condition of the experiment; independent repeated experiment is carried out on each ship ice breaking resistance experiment to reduce the influence of accidental factors; after the experiment is finished, interval division processing is carried out on experiment data, the experiment data corresponding to unreasonable sub-regions is eliminated on the basis of mathematical statistics, and uncertainty analysis is performed; and image correction is carried out on a broken ice region picture in the data before the experiment, sub-region pictures are obtained by carrying out sub-region-based division, the actual coverage rate of the sub-regions is calculated, and the ice breaking resistance in the experiment data corresponding to each remaining sub-region is corrected, so that the experiment data is more reliable.

Description

technical field [0001] The invention relates to an ice rink deployment and data processing method for ship ice crushing resistance experiments Background technique [0002] Due to global warming, Arctic shipping routes are increasingly becoming a reality. For the design of polar ships, ice resistance is a factor that must be considered. Therefore, it is extremely valuable to carry out the ship ice crushing experiment. However, the current guidance methods for ship ice crushing experiments, especially for the treatment process of the ice crushing area in the experiment, are still relatively scarce. Contents of the invention [0003] According to the above-mentioned technical problems, an ice field layout and data processing method for ship ice breaking resistance experiment is provided. The invention aims at the ice rink layout and data processing flow of the crushed ice resistance experiment of ships to solve the discrepancy between the actual situation of the crushed i...
