摘　　要：在建立弹靶模型的基础上,采用有限元软件LS-DYNA对装填尼龙的侵彻膨胀弹以不同着靶速度侵彻4340钢靶板的过程进行了数值模拟。结果表明:着靶速度对侵彻膨胀弹横向效应的产生有一定的影响。在PELE能够穿透靶板的前提下,随着着靶速度的进一步增加,横向效应的作用区域呈现出先减小后增大的趋势,而PELE穿透靶板后的速度损失越来越小;综合考虑横向效应的有效发挥和常规发射条件,PELE着靶速度的选取应选取800 m/s^1 300 m/s较为合适。Based on builiding model of the penetrator with enhanced lateral effect（PELE） and steel plate,,LS-DYNA finite element method software is used to simulated penetration of PELE filled nylon against 4340 steel plate using the different speed.As a result,the impact speed have definite influence on producing of lateral effect.On condition of PELE having penetrated target,with farther increase in impacting speed,operation region of PELE take on the direction of decrease firstly and augmentation thereafter,the remnant speed after penetrating target at the same time is less;Take into account validity of lateral effect and general launching condition,selecting the speed of impacting speed at the range of 800 m/s^1 300 m/s is suitable for PELE.
