| 摘 要： | 针对火工品在试验中不具有可重复检测性的特点,提出了一种基于活化能的加速贮存寿命试验优化设计方法.利用Arrhenius方程推导了火工品加速系数计算公式,初估了火工品活化能,进而根据活化能的理论估计值和需要验证的寿命指标来估计加速贮存寿命试验的截尾时间.以验证某火工品的贮存寿命指标为例,说明了该方法的操作过程,为减少试验设计中的不确定因素提供了一种新的思路.

| Abstract: | Aiming at the one-off characteristics of pyrotechnics, an optimum design method of the accelerated storage life test was advanced based on its activation energy. The accelerated coefficient formula were deduced on the basis of Arrhenius equation and the activation energy of pyrotechnics was calculated. Then the end time of the test was estimated. This method puts forward a new idea to reduce the uncertainty in the test design. |
