| description | To make up for the deficiencies in the present method of measuring microdetonator output energy, this paper uses PVDF (Polyvinylidene Fluoride) piezoelectric films as sensors and designs a system to test the output pressure of microdetonators with a 2.5 mm diameter. The average measured output pressure was 9.87GPa. In addition, detonation tests were carried out which showed that a microdetonator with a 10 mg charge could reliably detonate a JO-9C(III model) lead explosive with an 8 mg charge in a 0.7 mm air-gap. The detonation simulations for lead explosives using LS-DYNA software were consistent with the detonation test results. There was less than 5% error between the output pressure values and the test values of microdetonators. The results showed that PVDF piezoelectric films have rapid response times, high precision and low production cost in output pressure tests. The simulation model has practical significance for the quantitative evaluation of microdetonator output energy. |
