Effect of Parameter Variation of Viscoplastic Sea Ice Material Model on Ship Ice Collision

( Volume 5 Issue 9,September 2018 ) OPEN ACCESS

Lin Wang, Xiaogang Qian, Shuaishuai Zhu


In this paper, the nonlinear finite element method is used to select the viscoplastic ice material model to simulate the ship ice collision. The dynamic structural response characteristics of sea ice collisions under different parameters such as different density and elastic modulus are studied respectively. The collision energy absorption law and collision force under different working conditions are revealed. The ice constitutive model under different parameters is obtained. The mechanism of the impact on ship ice collision is to provide reference for improving the ship's anti-ice load design.
