摘要
为了研究发射载荷下战斗部装药内部孔隙的变形过程对发射药安全性的影响,采用ANSYS/LS-DYNA非线性有限元分析软件进行了数值模拟。结果表明,相同体积的椭球形孔隙和球形孔隙的变形特征相差很小。
In order to investigate the effect of the deformation process of interior pore of warhead under the lauch load on the safety of gun propellant, a numerical simulation is carried out by ANSYS/LS- DYNA software. The results show that there is little difference to elliptical and spherical pore with the same volume for the deformation characteristics.
