中文摘要:
      目的 提出装药结构在跌落/撞击事故条件下安全性的定量评估方法。方法 针对装药结构跌落/撞击条件下含能部件非冲击点火存在的不确定性大、缺乏可供工程应用的点火判据等问题,采用基于数理统计思想的定量评估思路,建立“3类试验+1种方法”的安全性评估体系,并提出试验设计、方法选取和评估实施的方法及要求,可供工程应用。结果 采用该方法,开展了某装药结构跌落安全性的定量评估,通过标准试验探索获得了特定约束下的起爆阈值范围,通过设计并开展多发能包络整体级响应的构型试验,获得的实验数据可作为评估的样本数据。采用单侧置信下限方法进行了定量评估,获得了安全度为0.999 99(置信度0.9)的定量评估结果。结论 该方法可实现对武器装备、航天发动机跌落/撞击条件下安全性的定量评估,但该方法仅适用于装药结构具有足够安全裕度的情况。
英文摘要:
      To propose a quantitative method for safety assessment of charge construction under the condition of droping/impact accident. Aiming at the problems of large uncertainty in the non-shock ignition of energetic components under the condition of the charge construction drop/impact, and lack of ignition criteria for engineering applications, a quantitative evaluation method based on mathematical statistics is adopted, and an evaluation system of “3 types tests and 1 method” is established. The methods and requirements of experimental design, quantitative evaluation method selection, and evaluation implementation are given, which can be used in engineering evaluation. Based on this method, a quantitative assessment of the drop safety of a certain charge construction is carried out, and the detonation threshold range under the specific constrains is obtained through exploration using standard tests. The safety value data of sample tests are obtained by designing and carrying out a configuration test which can envelope the overall response, and the quantitative evaluation result of safety is 0.999 99( with confidence level of 0.9). This method can realize the quantitative assessment of safety for weapon equipments and aerospace engines under drop/ impact conditions, but this method is only suitable for the situation where the charge construction has sufficient safety margin.
