为研究密闭爆发器试验压力损失对发射药起始动态活度比的影响,分别对未破碎发射药、低温和常温破碎硝胺发射药、破碎15/9发射药进行了起始动态活度比试验分析.根据实际试验条件与计算需求,采用能够修正密闭爆发器试验中燃烧全过程压力曲线的方法对不同破碎发射药试样的试验结果进行了压力修正,计算了压力修正前后破碎发射药的起始动态活度比的相对误差.分析结果表明,压力损失对发射药起始动态活度比的影响较小,在实际试验中可以依据实际条件选择是否进行修正.

To study the influence of pressure loss in closed bomb test on initial dynamic vivacity ratio(IDVR) of propellant, the IDVR was tested and analyzed for unfractured propellant, fractured ammon propellent under low-temperature and normal temperature,and fractured 15/19 propellant,respectively. According to actual testing conditions and computational requirement, a method of correcting pressure curve of whole burning process in closed bomb test was adopted to correct the testing results of different fracture propellant samples,and the relative error of IDVR of fracture propellant was computed. Analyzed result shows that pressure loss has a little effect on the computation of IDVR, and it depends on actual conditions in test whether or not correct pressure loss.
