摘要
为探讨冰、水、结构物之间的相互作用关系,采用近场动力学方法建立二维冰-水-圆柱结构物的运动计算模型,采用近场动力学微分算子模拟海水流动,采用常规态型近场动力学模拟海冰的损伤行为以及海冰与结构物之间的作用.进一步研究不同圆柱结构物移动速度和直径对冰载荷的影响,将数值计算结果与试验结果进行对比以验证方法的可行性,为研究冰、水、结构物相互作用提供理论支撑.
Abstract
The interaction of ice-water-structure is one of the common phenomena in the study of polar engineering.In order to explore the interaction relationship between ice-water-structure,a two-dimensional ice,water,and cylindrical structure calculation model is established by using peridynamic theory.The peridynamic differential operator is adopted to simulate the flow process of fluid.The normal state peridynamic is used to simulate the damage behavior of sea ice and the impact between sea ice and structures.The influence of the moving speed and the diameter of the cylinder on the ice load is further studied.The numerical calculation results are compared with the experimental results to verify the feasibility of the method,which provides theoretical support for the study of ice-water-solid interaction.
