摘要
目的评估含能材料产品在热烤环境下的热安全性,研制一套热烤环境试验用多温区热控装置。方法从热烤试验需求出发,制定试验系统功能、指标。进行系统功能分解,重点分析加热方式和加热元件的选型,温区之间的温度耦合及控制。基于试件含能,危险性较大的情况,制定安全策略。基于组态软件实现热控系统的软件设计,考虑了参数及曲线设置、试验过程状态观测、数据存储、报警和安全保护等。结果利用该多温区热控系统开展了验证性试验,设置的温度为室温~229℃,温变速率为6℃/h,三温区控制,温度误差为±1.5℃。结论含能材料热烤试验用多温区热控装置可以完成大试件小温升速率热烤试验的要求,为大尺寸含能材料热烤试验提供了试验能力。
The paper aims to evaluate the safety of energetic materials products under cook-off environment,one heat test apparatus is developed.In this paper,the functions and index of the apparatus are formulated from the needs of the cook-off test,especially the selection of heating mode and heating element,and temperature coupling and control between temperature zones.Safety strategies are made in consideration of the dangerous of the energetic materials.The software design of the heat system is accomplished through configuration technology,including set of parameters and curves,status observation of test progress,storage of data,alarms and safeguard strategy.A simulated test piece for energy-containing material is designed and a functional verification test for the thermal control device is carried out.The scope of the temperature is from normal temperature to 229℃with a rising rate at 6℃/h under the control of three temperature zones..The results show that the deviation of the temperature is within±1.5℃.The design of the thermal control device for the hot baking test with small temperature rise rate can meet the requirements of the hot baking test..The heating element with matching heating capacity should be selected in the test design stage, and the heating power output state of the thermal control device should be maintained in good condition.
