研究简介Abstract

碎冰区航行涉及大量离散冰块的接触、平移、旋转与再碰撞。为减少不同冰块在背景网格速度场中的非物理混合，研究采用按冰块身份区分的多速度场物质点计算框架，并从船体阻力、冰块运动和接触网络等方面分析冰况及航速的影响。

Navigation through fragmented ice involves repeated floe contacts, translations, rotations, and collisions. To mitigate artificial mixing of distinct floes on a shared computational grid, this project investigates a floe-resolved, multi-velocity-field MPM and examines ship resistance, floe dynamics, and contact networks over varying ice conditions and vessel speeds.
