中文摘要:
      应用有限元方法, 通过算例模拟了桥丝式电火工品(EED)静电发火的三维温度场,并采取统计方法估算了火工品临界发火温度;结合可靠性理论应力-强度模型,采用蒙特卡罗方法,计算了EED在人体静电作用下的发火概率;最后分析了各因素对火工品发火概率的影响。结果表明,人体静电电压是影响桥丝式EED发火概率的最主要因素,EED在人体静电作用下的发火概率高达17.1%
英文摘要:
      By a concrete example, the finite element method was used to simulate the three dimensional temperature field of bridge wire electric explosive device (EED) during ignition under the action of electronic static discharge (ESD). The critical ignition temperature of EED was estimated by statistical methods. According to a stress-strength model of reliability theory and using Monte-Carlo simulation method, the ignition probability of EED under the action of human body ESD was calculated. The influences of different factors on ignition probability of EED were analyzed. The results showed that human body electrostatic voltage is the main factor influencing the ignition probability of EED; the ignition probability of EED under the action of human body ESD can reach up to17.1%.
