Numerical Model of Striking the Percussion Cap in the Air Force Institute of Technology (AFIT) Test Device
Journal Title: Problemy Mechatroniki. Uzbrojenie, lotnictwo, inżynieria bezpieczeństwa - Year 2013, Vol 4, Issue 4
Abstract
Results obtained on the device described in [1] were interpreted by means of the numerical model. A conformity of the model and experimentally based profiles of delay time (400-100 s), firing pin immersing (360 m approx.) and the absorbed energy (160 mJ approx.) up to the moment of percussion cap igniting versus the striking mass energy (200-1500 mJ) was obtained. A discrepancy of the energy values that determined with an aid of accelerometer mounted on the striking mass and that absorbed in the cap material (metal and pyrotechnic substance) depends on the delay time in a given mechanical system. The energy utilized to ignite a pyrotechnic material (3.3 mJ approx.) is much smaller then the total absorbed energy.
