Abstract
In order to study the ignition performance of self-powered overload igniter based on Lead Zirconate Titanate (PZT), shock simulation tests for different electro-explosive devices (EED) were carried out by using separated Hopkinson pressure bar to simulate overload environment. The output energy of PZT, temperature rise process of bridge wire in EED, initiation temperature of the detonator, ignition energy, and initiation delay of igniter are experimentally analyzed. The experimental results show that: 1) the matching degree between the resistance of EED and PZT plays a key role in the sensitivity of the igniter; 2) Whether the igniter can detonate successfully depends not only on the maximum overload but also on the overload action time; 3) During the ignition process, the initiating explosive starts to react before the bridge wire fuses; 4) There is a delay time from the output energy to the reaction temperature of the initiating explosive to the complete reaction of the initiating explosive, which is the main reason for the delay of the igniter.
