摘要:
为降低X型爆炸箔点火器的发火电压，提高点火可靠性，设计了一种带约束管的爆炸箔点火器。它由壳体、约束管、点火药、盖片和堵盖等组成，外径为18.00 mm，高度为25.00 mm；输入点火药选用爆发点较低的热敏感型B/KNO3点火药，装药密度为（1.45±0.05） g/cm3，装药量为（0.13±0.05） g；输出点火药选择许用B/KNO3点火药，装药密度为（1.75±0.05） g/cm3，装药量为（0.62±0.05） g；输入装药约束管外径为5.00 mm，高度为4.50 mm，厚度为0.50 mm；输出装药约束管外径为8.00 mm，高度为7.00 mm，厚度为0.50 mm。并对爆炸箔点火器进行结构强度仿真和主要性能测试。结果表明：点火器在点火过程受到的最大应力约为54.513 MPa，最大应变约为3.699 3×10－4；输出压力为17.90 MPa；50%发火电压为672 V。满足了使用要求。
Abstract:
In order to reduce ignition voltage of the X-type exploding foil igniter and improve its ignition reliability, an exploding foil igniter with restraint tubes was designed. It consists of a shell, a restraining tube, ignition powder, a cover, and a plug, with an outer diameter of 18.00 mm and a height of 25.00 mm. The input ignition powder is a thermal sensitive B/KNO3 ignition powder with a lower explosion point, with a charge density of (1.45±0.05) g/cm3 and a charge amount of (0.13±0.05) g. Permissible B/KNO3 ignition powder is selected as the output ignition powder, with a charge density of (1.75±0.05) g/cm3 and a charge amount of (0.62±0.05) g. The outer diameter of the input charging restraint tube is 5.00 mm, the height is 4.50 mm, and the thickness is 0.50 mm. The outer diameter of the output charging restraint tube is 8.00 mm, the height is 7.00 mm, and the thickness is 0.50 mm. Structural strength simulation and main performance test were conducted on the exploding foil igniter. The results show that the maximum stress and strain experienced by the igniter during the ignition process are approximately 54.513 MPa and 3.699 3×10-4, respectively. The output pressure is 17.90 MPa. The 50% firing voltage is 672 V. It meets the usage requirements.
