摘要
利用动态活度定义推导了动态活度比,提出了用起始动态活度比描述发射药破碎程度的方法,研究了破碎发射药动态活度比数据处理方法.对几种不同形状、不同破碎程度发射药的起始动态活度比进行了计算.结果表明,起始动态活度比随发射药破碎程度增加而增大,这与试验结果一致.
The dynamic vivacity ratio was deduced by using the definition of dynamic vivacity. The method of describing fracture degree of propellant using initial dynamic vivacity ratio was put forward, and the method to deal with fracture propellant data of dynamic vivacity ratio was also studied. The initial dynamic vivacity ratio of few kinds of different shape propellant with different fracture degree were computed. The results show that the initial dynamic vivacity ratio increases with the increase of fracture degree of propellant, which is agreement with the experiment.
