摘要
弹靶参量是影响PELE后效的重要参数,为分析着靶速度、弹丸壳体厚度、靶板厚度对PELE横向效应的影响,通过建立PELE垂直侵彻金属薄靶板的理论模型,阐明横向效应的产生机理;利用有限元软件AUTODYN对横向效应增强弹撞击金属薄靶的过程进行数值模拟。结果表明:在着速为900~1400m/s范围内,提高着靶速度,PELE穿靶后外壳径向速度增大;弹丸壳体厚度在1~3.5mm范围内,弹丸的横向效应随着壳体厚度的增大而减弱;在一定靶板厚度范围内,随着靶板厚度的增加,弹丸的轴向消耗相应增加。
Projectile target parameters are important parameters that affect the aftereffect of PELE.In order to analyze the transverse effect of target velocity,shell thickness and target plate thickness on PELE,the theoretical model of PELE vertical penetration of thin metal target plate was established to clarify the mechanism of transverse effect.Finite element software AUTODYN was used to simulate the process of transverse effect enhancing projectile impact on thin metal target.Results show that the target speed is improved with 900~1400 m/s range,PELE shell after wearing a target radial velocity increases;Projectile shell thickness is in 1~3.5 mm,and the projectile lateral effect weakens with the increase of the thickness of the shell;Target plate thickness is in a certain range,and with the increase of target plate thickness,projectile axial cost increases accordingly.
