摘要
有许多因素引起膛内危险压力波甚至爆炸.本文讨论了另一个可能的因素,火药颗粒内部的热应力而导致火药的破碎.文中假设颗粒为球形的,推导了理论结果,获得了最大热应力公式,并讨论了一些相关的问题.
As we know.There are many factors leading to dangerous pressure waves,even breechblows.This paper makes an examination of another possible condition caus-ing the breechblows,the thermal stress within propellant grains.The propellant grainsbeing assumed as spherical grains,this paper derives some theoretical results,obtains aformulas about the maximum thermal stress,and discusses some relative problems.
