Abstract: The present disclosure discloses a method of ice distribution and data processing for ship ice resistance experiment in broken ice field, the ice floe is uniformly distributed in the broken ice field before each ship ice resistance experiment with eliminating the mutually overlapped broken ice to make it close to the experimental design working condition, and independent repeated experiments are carried out on each ship ice resistance experiment to reduce the influence of accidental factors; after finishing the experiment, the experimental data are divided into intervals and the experimental data corresponding to unreasonable subdomains are eliminated by mathematical statistics, and the uncertainty analysis is carried out; image correction is carried out for pictures of in broken ice field in the pre-experimental data, and the pictures are divided to obtain subdomain pictures to calculate the actual coverage rate of each subdomain; the ice resistance in the experimental data corresponding to each remaining subdomain is modified, so as to make the experimental data more reliable.
