摘　　要：弹体底部厚度是影响横向效应增强型弹药(简称PELE)横向效应的一个重要因素。为了分析弹体底部厚度与PELE的横向效应之间的关系,弹芯、靶板不改变,仅改变弹体底部厚度,以ANSYS/LS-DYNA软件为平台对不同底部厚度的PELE作用不同厚度靶板的过程进行了数值仿真。通过破片的横向速度比较不同弹体底部厚度下PELE的横向效应,获得弹体底部厚度对PELE横向效应作用的影响规律。The bottom thickness of projectile is a crucial factor that affects the lateral efficiency of PELE bullet. In order to studying the connection between the bottom thickness of bullet and the lateral efficiency of PELE bullet, the core of projectile, the thickness of target is kept the same, but the bottom thickness of PELE bullet is changed. PELE of different bottom thickness impacting target is simulated by the non-linear dynamic software LS-DYNA. The lateral efficiency is charged by lateral velocity of fragments. The law is found by the results of numerical simulation.
