摘要:
针对不敏感引信传爆序列热安全性设计的迫切需求,提出了引信慢速烤燃特性的等效试验方法。该方法通过建立导爆药、传爆药与壳体为耦合的热传导界面,且在耦合界面上温度和热流连续的引信慢速烤燃仿真模型,对不同升温速率条件与标准试验方法的慢速烤燃特性进行对比仿真,得到等效试验方法,缩短慢速烤燃试验的耗时,提高研究效率。仿真和试验结果表明,1 ℃/min和3.3 ℃/h不同升温速率下,引信反应程度基本相同,反应温度相差不超过3%。因此,可以采用1 ℃/min的升温速率代替3.3 ℃/h的升温速率进行等效试验,以缩短引信慢速烤燃特性试验的时间,提高研究效率。
Abstract:
Aiming at the urgent need for thermal safety design of detonation sequence of insensitive fuze, an equivalent test method for slow cook-off characteristics of fuze was proposed. The influence of heating rate on the characteristics of fuze was obtained by simulation, and the experimental verification was completed. The simulation and test results showed that the fuze booster reacted earlier than the detonator,. When the heating rate was 1℃/min and 3.3℃/h, the reaction degree of fuze was almost the same, and the difference of reaction temperature was not more than 3%, so the equivalent acceleration of 1℃/min could be used instead of 3.3℃/h in the test, which could greatly improve the research efficiency. Therefore, the 1℃/min could be used to replace 3.3℃/h as the heating rate for equivalent test method, so as to shorten the test cycle and improved the research efficiency.
