A particular analysis research on bullet launching process is made, and the relation between the length of bullet and the velocity of detaching from the carrier and the relation between the length of bullet and burning rate of powder and the relation between the length of bullet and maximal pressure of emission hole and the relation between the length of bullet and the emitting time are gained.
对子母式穿甲弹子弹的发射过程进行详细的分析,得出了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,为子母式穿甲弹设计提供了依据。
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.
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。
The new theory of launching over-loading of charge is proposed in the paper.
