Abstract

To explore the influence of bridge area width and the material of acceleration chamber on flyer speed, AUTODYN was used to simulate the process of flyer driven by electric explosion of bridge foil. The results show that, compared with bridge width of 0.27 mm, 0.30 mm, 0.33 mm, 0.36 mm and 0.42 mm, the speed of the flyer driven by the bridge width of 0.24 mm is the largest. Compared with aluminum, nickel and copper, Al₂O₃ ceramic accelerator improves the speed and shear effect of flyer with small deformation due to its high hardness. Al₂O₃ ceramic is better than the other three kind of materials as acceleration chamber.
