| 摘 要： | 在电火工品一维热传导方程的基础上,给出了电火工品热传导方程,并用变分法推导了电火工品临界参数值的计算公式.通过对药剂HMX,PENT,RDX的计算表明,临界点火条件和临界点火温度随药剂活化能的增大而减小,随桥丝输入能量的增大而增大,临界点火时间则随桥丝能量的增大急速减小.

| Abstract: | Based on the 1 D heat transfer model of EEDs, their heat transfer functions are given, and the variational model adopted to calculate their critical values. The results show that the critical ignition condition and critical ignition temperature can be minimized when E increases, and it tends to be increased when the energy increases. It also shows that the critical ignition time tends to be strongly minimized an increase in energy. |
