褶皱外观，镀铬钢闭锁环和压模锌线结构 - In this paper , firstly the macro parameter of the series connection app was comprehensively analyzed , among which the trajectory location of the bullet emission and the terminal velocity of the bullet were mainly analyzed , and the feasibility of the series connection app to cope with explosive reactive armor was demonstrated . and then the macro design about the head of the series connection app was made , among which a particular analyse about the bullet " s launching process was made , from which we concluded the relation between the thickness of the airproof loop and the velocity of the bullet detached from the carrier and the relation between the length of the bullet and the velocity of the bullet detached from the carrier and the relation between the length of the bullet and the burning rate of the powder and the relation between the length of the bullet and the maximum pressure of the emission hole and the relation between the length of the bullet and the emitting time of the bullet , and the reasonable str ucture of the head of the carrier and bullet were designed , then the intensity of the head of the carrier was checked out using of the software of ansys
本文首先对子母式穿甲弹总体参量作了全面的计算分析，其中主要分析了子弹射出的弹道位置和必要的子弹着靶速度，论证了子母式穿甲弹对付爆炸式反应装甲的可行性，然后对子母式穿甲弹弹头部进行了总体设计，其中主要对子弹的发射过程进行了详细的分析，得出了母弹弹头部发射孔内闭锁环厚度与子弹飞离母弹速度的关系、子弹长度与子弹飞离母弹速度的关系、子弹长度与火药燃烧率的关系、子弹长度与母弹弹头部发射孔内最大压力的关系以及子弹的长度与子弹发射所需时间的关系，设计出了合理的母弹弹头部结构和子弹的结构，并利用ansys有限元分析软件对母弹弹头部的强度进行了校核。
