Ship Local Structure Damage Simulation Subjected Underwater Explosion

采用理论分析以及数值计算的方法对水下爆炸作用下水面目标的局部毁伤效应进行研究。首先对水面目标局部毁伤种类进行说明,然后建立了挠曲变形理论计算模型;选取典型目标,采用计算模型对其毁伤效应进行计算,计算结果同模型试验测试进行了比对分析。比对结果表明模型计算结果与试验测试结果在局部毁伤效应方面结果一致,验证了模型的正确性以及计算方法的可行性。

Ship local structure damage effect subjected underwater explosion has been studied by using theory analysis and numerical simulation method.Firstly,form of local structure damage has been introduced;secondly,the numerical model of deformation and crevasse has been established.The structure damage effect of classical ship has been gained according those models and the results have been compared with experiment data.These show that those two methods have been achieved the same results in protecting ship local structure damage effect.Those results have validated correctness of theory model and feasibility of numerical simulation.
