| 摘 要： | 为研究心形装药结构的破片飞散特征与能量增益效应,基于LS-DYNA对典型心形装药结构与同质量和尺寸的轴对称装药结构的破片驱动飞散、能量分布和对靶板侵彻作用效应进行了数值模拟,结果表明心形装药结构在径向飞散角-30°~30°内的破片比例为94.3%,而轴对称装药结构仅为16%.心形装药结构的破片速度在2097~349 m/s之间分布,平均速度虽明显低于轴对称装药结构,但在径向飞散角-5°~5°之间的破片总动能约是轴对称装药结构的4倍,能够明显提高定向方向范围内的破片分布密度和动能,增强对目标的侵彻作用效应.

| Abstract: | To study on fragments dispersal characteristics and energy gain effects of a heart-shaped charge, comparisons with the same quality and size of an axisymmetric charge kinetic energy distribution and penetration effects on a target plate were simulated by LS-DYNA in fragments scattering. Results show that fragment proportion of the heart-shaped charge in radial dispersal angles between -30° and 30° is 94.3%, and the axisymmetric charge is only 16%. Fragment velocities of the heart-shaped charge are range from 2097 m/s to 349 m/s, which are lower than that of the axisymmetric charge. The total kinetic energy of fragments of the heart-shaped charge is 4 times of the axisymmetric charge in radial dispersal angles between -5° and 5°. Research illustrates that the heart-shaped charge enhances fragments distribution density, kinetic energy and penetration effects on a target plate in the specified direction. |
