摘要
描述了进行相应数值模拟计算所需的计算方法和关键技术,以及弹体、战斗部、舰船结构的本构模型及其相应参数的确定方法。通过典型算例计算得到数值仿真结果,与试验数据对比定性符合。在此基础上研究了反舰导弹武器对某型舰船的损伤,分别给出破坏模式效应图像、损伤范围等图表及曲线,旨在为研究舰船防爆抗冲击提供依据。
In this paper ,the numerical simulation methods and key technologies of calculating the deformation of warship under cross-cabin load are described with the constitutive model of missile ,warhead and ship structure ,as well as the corresponding parameters . The typical example which indicates qualitative coincidence between the numerical simulation results and experimental data is presen-ted .Damage of the warship subjected to missile penetration and explosion is studied by the above-mentioned methods while charts and curves of damage effect and extent under damage model are given in this paper ,which provides the basis for the research of ship impact resistance .
