摘要
According to the hysteresis quality of ship collision,this paper puts forward a concept of lag coefficient, and then subdivides the process of ship collision into two stages, i.e. plastic collision and elastic collision, thus the algorithm foundation of ship collision is improved. Then, the recovery coefficient is solved for the first time by the coupling principle of internal and external dynamics. Finally, the ice force time history curve and other characteristics of the collision load are calculated by the central difference method. © 2020, Editorial Board of Journal of Ship Mechanics.
