The safety and reliability of the initiating explosive devices (IEDs) are critical for the weapon system. As the core components of IEDs, the method of resistance designing and the performance of conversion energy of energy conversion components (ECCs) are worth being studied. In this paper, the design method for the resistance of ECCs is established based on the finite element discrete method, and the currents of melting and electric explosion are presented for evaluating the performance of ECCs. The results show that the resistance of the ECCs is 1 ± 0.05 Ω with consistency. The ECCs were designed by the established design method of resistance and manufactured by the established machining method. The melting current of ECCs is 1.8 A, which is calculated by the infrared temperature measurement and finite element simulation. The electric explosion current of ECCs is 5 A, which was obtained by combining the snapshot obtained via the high-speed camera and finite element simulation. [ABSTRACT FROM AUTHOR]

In this study, a novel high-speed flyer launching strategy based on electric explosion and laser coupling was proposed to improve the launching ability of electro-explosively actuators and expand the dynamic high-pressure loading method. First, an electro-explosively actuated flyer launcher with a transparent glass substrate was fabricated by microelectromechanical system (MEMS) scale methods, which acted as a carrier to verify the idea of electric explosion and laser coupling. Then, a device of electric explosion combined with laser driving high-speed flyers was established to study the influence of nanosecond pulsed laser on the flyer launching ability of electro-explosively actuators. Finally, the velocity characteristics of the flyer and the plasma characteristics under coupled conditions are studied. The test results indicated that the introduction of laser had a positive effect on increasing the speed of the flyer. In addition, it was found that the acceleration history of the flyer is affected by the energy of electric explosion, laser energy, and the introduction time of laser. [ABSTRACT FROM AUTHOR]
