Numerical simulation of the ignition law for a hot bridge wire electroexplosive device

Xuxu Lyu et al.

Summary: This paper studies the thermal ignition process and safety testing technology of hot bridge wire electroexplosive devices (EEDs). By constructing a temperature rise model and conducting theoretical and numerical analysis, the sensitive criterion for ignition of a hot bridge wire EED is determined. The research also explores the impact of bridge wire and reagent parameters on the ignition process. The findings demonstrate that the first derivative of the reagent temperature with respect to the radial distance is a sensitive criterion for accurate ignition. The study provides guidance for safety testing, production, and use of hot bridge wire EEDs.

Feasibility and Error Analysis of Using Fiber Optic Temperature Measurement Device to Evaluate the Electromagnetic Safety of Hot Bridge Wire EEDs

Xuxu Lyu et al.

Summary: Most studies assessing the safety of hot bridge wire EEDs use temperature sensors without analyzing the accuracy of the temperature measurement. This study establishes the response function of the exposed bridge and temperature rise system, comparing and analyzing their characteristics under different excitations. The results show that temperature rise measurements can be directly applied under steady conditions but not under pulse conditions.
