计及结构变形能的冰载荷快速计算方法

摘要

The structural deformation energy was evaluated analytically in three typical positions of ice collisions with side grillage.The modified energy method considering structural deformation energy of evaluating ice loads was presented.The maximum ice loads and load-time curves were presented when ships strike the finite ice of various contact geometry in three typical positions of side grillage by MATLAB programs.The method can evaluate the local ice loads of ice-going ships rapidly and accurately.%借助解析方法估算出的船冰碰撞中舷侧3个典型碰撞位置结构变形能,对计算冰载荷的能量法进行修正和完善,得到计及结构变形能的冰载荷计算能量法,采用MATLAB编程计算得到不同接触面形状的有限大海冰与船舶舷侧3个典型位置相撞时的最大冰载荷和冰载荷随时间变化的曲线,实现了对冰区航行船舶局部冰载荷快速而准确的估算.
