摘要
随着极地资源的探测以及北极航道的开发,航行于极地的船舶数量与日俱增,碎冰作为极地典型海冰类型在研究船冰碰撞中需重点考虑,然目前构建碎冰的方法还不完备。现基于元胞自动机的理论创建碎冰位置,利用泰森多边形对生成的元胞点建立多边形模拟碎冰模型,结合MCD理论验证碎冰仿真模型的真实性,分别对碎冰尺度、概率分布和碎冰厚度进行优化,且将优化后的模型再次用MCD理论验证,得到接近真实碎冰冰情的碎冰模型,可为极地碎冰模型的构建提供一定参考意义。
With the exploration of polar resources and the development of Arctic shipping routes,the number of ships sailing in the polar region is increasing day by day.Broken ice should be considered in the study of ship-ice collision as a typical polar ice.However,the methods for constructing broken ice are not complete at present.Now,the theory of cellular automata created location for broken ice.Using the cell points to build a polygonal simulation model of broken ice by Voronoi diagram.The authenticity of the broken ice simulation model can be verified with MCD theory.Then the scale,probability distribution and thickness of the broken ice are optimized separately.What’s more,the optimized value will be optimized after each step of optimization and verified by MCD theory again to make the broken ice model close to the real broken ice condition.It can provide a certain reference meaning for the construction of polar ice crushing model.
