| 摘 要： | 为了研究中心孔对聚能装药成形的影响,利用ANSYS/LS-DYNA软件对中心带孔聚能装药的成形过程进行数值模拟研究,研究了其成形过程,并分析了不同的中心孔直径对侵彻体成形情况和性能的影响。研究结果表明:当中心孔直径为装药直径的15%~20%时,在三倍装药直径距离处,侵彻体头部速度明显提高,侵彻体外形良好,其中,中心孔直径为装药直径的15%,头部速度最高,外形最好。

| Abstract: | In order to research on the influence of the center-hole on shaped charge's formation,the effort did the numerical simulation research on the center-hole shaped charge's formation process using the ANSYS/LS-DYNA software,revealed its formation mechanism,and studied the influence of six different sizes center-holes on its formation situation and the performance parameters.Test results showed that when the penetrator at a standoff of 3 CD,center-hole diameter accounted for 15%~20% of charge diameter,the foreh... |
