| Abstract: |
| 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. |
