摘  要:依据GJB 4300-2002《军用防弹衣安全技术性能要求》中Ⅳ级的防破片等级要求,采用数值仿真方法对陶瓷-钢板组合式防护层的防弹性能进行研究。设定相应等级的初始速度,通过改变陶瓷板和钢板的厚度进行建模仿真,确定2种材料厚度对整体抗弹性能的影响。仿真结果表明,当陶瓷靶较厚时,钢板只起到整体支撑作用,对抗弹性能几乎没有影响,钢板的厚度可根据对靶板最大变形量的要求适当选取。因此,要满足GJB 4300-2002中Ⅳ级的防破片等级要求,陶瓷靶板的厚度应在12 mm以上。According to standard IV fragment-proof grading requirements of GJB 4300-2002 Army Bullet-Proof Vest Safety Technology Requirement,use numerical simulation method to study the bullet-proof performance of ceramic/ steel targets.The initial velocity was set,and then through changing thickness of two materials,the entire bullet-proof performance of different states was confirmed.The results of simulation showed that,when the thickness of ceramic plate was large,the bullet-proof performance was effect slightly by steel plate.Then the thickness of steel plate can be selected following the demand of maximum deforming.The conclusion is that,if the demand of standard IV in GJB 4300-2002 could be met,the thickness of ceramic plate must be above 12mm.The results are useful to engineering application.
