摘要
数值模拟方法是当前主要的冰阻力研究方法之一,能对船舶破冰的全过程进行快速模拟,具有模拟成本低、参数易于控制和结果较为准确等优点。简要梳理冰区航行船舶冰阻力数值研究进展情况,包括基于网格单元的有限元模型,基于无网格方法的离散元模型、SPH法和近场动力学模型,以及网格模型与无网格模型的耦合方法。基于研究现状,提出尚需进一步解决的问题,为进一步提高冰阻力数值模拟精度提供参考。
Ice resistance is one of the key factors that affects the navigation performance of ships.It can do quick simulation of the whole progress of ship ice breaking with advantages of low cost,flexible parameter control and relatively accurate results.The paper briefly reviews the progress of numerical research on ice resistance of ships sailing in ice areas,including finite element model based on grid element,discrete element model based on meshless method,SPH method and Peridynamic method,as well as coupling method of mesh model and meshless model.Based on the current study situation,problems to be solved are puts forward,which provides reference for further improving the accuracy of ice resistance numerical simulation.
