    摘要:

    由于气候变暖,北极冰盖正在以更快的速度融化,北极航道的利用价值也愈渐升高。根据我国第七次科学观测北极海冰空间分布情况,模拟真实碎冰分布,采用LS-DYNA软件中的流固耦合方法,研究了不同碎冰尺度、碎冰厚度、碎冰域密集度及船舶航行速度对船冰碰撞中船体结构响应的影响,获得了船体结构损伤应力大小、能量吸收及碰撞力等结构响应规律和力学特性。

    Abstract:

    As the climate warms, the Arctic ice cap is melting at a faster rate, and the sea lanes are becoming more valuable. According to China's seventh scientific observation space distribution of the arctic sea ice, simulate the real distribution of broken ice, using ls-dyna software method of fluid-structure interaction, studied the different size broken ice, ice thickness, broken ice field intensity and the speed of ships sailing on the ship hull structure in the collision response, the influence of the hull structure damage stress, energy absorption, and the collision force and structure response law and mechanical properties.
