摘要/Abstract

摘要： 极地船舶舷侧结构时常与层冰发生挤压,探究这一作用机理对于极地船舶设计和安全运营至关重要。该文采用离散元分析方法建立了层冰与舷侧作用的数值仿真模型,利用室内冰水池开展舷侧挤压冰载荷模型试验,对数值模型的合理性进行验证。基于所建立的层冰与舷侧挤压数值模型,研究分析了层冰漂移方向与艏向夹角变化对舷侧挤压冰载荷的影响,探讨了舷侧挤压作用机理及非线性冰载荷分布规律,为层冰与舷侧挤压场景的冰载荷及结构响应预测提供了技术支撑。

Abstract: Extrusion between the side structure and the level ice is one of the most common scenarios encountered by polar ships. It is of great significance for the design and operation of polar ships to explore the mechanism of the extrusion between the level ice and the broadside. A numerical simulation model of the interaction between the level ice and the broadside is established by using the discrete element method in the current study. The rationality of the numerical model is verified based on the results of a model test on the ice loads during the broadside extrusion conducted in an indoor ice tank. The influence of the variation of the angle between the level ice drift direction and the ship's heading on the ice loads during the broadside extrusion is studied and analyzed based on established numerical model of the extrusion between the level ice and the broadside. The mechanism of the broadside extrusion and the distribution law of nonlinear ice loads are discussed. It can provide technical support for predicting ice loads and structural responses in the scenario involving the extrusion between the level ice and the broadside.

Key words: level ice, ice load, discrete element method, ship-ice extrusion
