Study on Transverse Harmonic Rolling Model in Ship Waves

In recent years, China's ships are gradually moving toward deep blue, and the maritime trade with other countries is becoming more frequent, especially with the expansion of the “Maritime Silk Road”, which has promoted this trend. China's ships will encounter various complex sea conditions, and it is no longer possible to guarantee the safety of navigation by simply manipulating the ships with experience. At present, many scholars have conducted a lot of research and practice on the navigation safety of ships in waves, especially in the harmonic oscillation of waves, and have obtained a number of enlightening and constructive research results. In this paper, according to the information parameters of the ship itself and the parameters of the sea wave, the transverse harmonic roll model of the ship in the wave is established, the harmonic roll coefficient and the harmonic roll danger area are solved, and the theoretical reference is provided for the study of the suppression of the harmonic roll of the ship in the wave.
