Abstract: |
In order to study the impact of high and low temperatures on the firing performance of firearms, a simulation test device for firearm ignition was used to conduct ignition tests of firearms under high and low temperature environments. This resulted in obtaining the pressure time curves of truncated shells under high and low temperature conditions. Additionally, numerical simulations of the ignition performance under high and low temperatures were carried out, calculating the characteristic parameters of the ignition powder temperature, stress, and primer output pressure. The simulation results were compared with the experimental data, and the maximum relative error of the characteristic parameters of the primer pressure was less than 15%, which verified the correctness of the simulation model. This model can effectively simulate the response process of firearm ignition. This study can provide a certain theoretical basis for improving the primer design and enhancing the reliability of firearms in high and low temperature environments, which is conducive to enhancing the performance and combat effectiveness of firearms in extreme environments. |
