摘要
提出了对蜂窝芯层进行SPH离散化的平移阵列法,可形成蜂窝芯层的SPH几何模型数据。采用LS—DYNA软件的SPH功能,对蜂窝夹层板超高速撞击过程进行了仿真研究。仿真结果显示,蜂窝芯层限制了碎片云的径向飞散,改变了碎片云的形态。
A method used to dispersing the honeycomb type plate is put forwarded, called paralleled moving array. With this method, a practical honeycomb type plate case is dispersed into SPH geometry model. The SPH simulation of this case is done. The result show that it is defference than two-layer plate, the debris shape is limited in radial derection.
