Abstract
The physical mechanism of the exploding wires should be most important in the investigation of the initiation characteristics for Capacitor Discharge Unit(CDU) with exploding wires which shows a strong non-linear resistance characteristic. In this paper, the resistivity versus specific action data are used to describe the electrical characteristics of exploding wires, and linear interpolation is combined to predict their behaviors. A PSPICE model is built to simulate the CDU circuit with exploding wires. And corresponding experimental platforms are built to measure the working current and voltage of the exploding wires. The simulation results by PSPICE are general consistent with the measurement results. The difference of material characteristic will influence the detonation synchronicity with series exploding wires; while the detonation synchronicity and reliability will be influenced significantly by both the material characteristic and dimension with parallel exploding wires. The results suggest that the simulation model can be used to quantitatively evaluate the detonation synchronicity and reliability for multiple exploding wires detonation.关键词
