| 目的 在装药结构的热安全性试验时选择合理的加热方法。方法 从燃料、加热速率、温度范围、温度可控性、温区可控性、对试件影响等方面对开放油池火烧、可控喷射火烧、红外辐射灯阵、电加热带、电加热箱等常用的加热方式进行对比分析。结果 对于快烤加载，红外辐射灯阵兼具开放油池火烧和可控喷射火烧的优势，能够实现温度为800~1200 ℃、升温速率不低于200 ℃/s、温度控制偏差不大于5%的模拟火烧温度稳定控制，且具备清洁环保的优势；对于慢烤加载，红外辐射灯阵兼具电加热带和电加热炉加载的优势，能够实现温升速率3.3 ℃/h~1.0 ℃/min可调节，加热温度不低于400 ℃，温度分区不低于4个的分区慢速烤燃温度控制，且不会给试样反应等级带来额外影响。结论 合理选择慢烤、快烤加热方式，避免对装药结构的反应等级产生影响，是装药结构的热安全性试验时需重视的一个问题。 |

| In order to choose an optimized heating methods of the thermal safety performance for ammunition structures. The comparison analysis from the aspects of fuel, heating rate, temperature range, temperature controlled, and its effects to ammunition reaction of the open pool fire, controlled propane jet fire, electric heating swathes, electric heating case and infrared radiation lamps array. For fast cook-off test heating methods, the infrared radiation lamps array had the advantages of open pool fire and improved temperature controlled propane jet fire. It could imitated the flame temperature whose temperature region was located 800~1200 ℃, temperature rising rate was not lower than 200 ℃/s, temperature offset was not greater than 5% and had advantage of cleanness and environmental protection. For slow cook-off test heating methods, the infrared radiation lamps array had the advantages of electric heating swathes and electric heating case. It could imitated the slow cook-off temperature whose temperature region was not lower than 400 ℃, temperature rising rate was regulated between 3.3 ℃/h~1.0 ℃/min, temperature domains were not fewer than 4 and could not produce added influence to the reacting degree. Optimized choosing of the fast/slow cook-off heating methods which avoided effecting the reaction degree of ammunition was an important problem for the heating safety test of ammunition structures. |
