| Cluster munitions as a indispensable types of ammunition for large-caliber artillery,rocket launchers or tactical missiles and other launch weapons,often used to attack the long distance enemy tank group and cluster goals on the ground.The key to improving the damage effect of the cluster munition is to ensure that it has a reasonable diffusion range and spread density,to prevent the bullet explosion.Therefore,this paper has studied the testing technology of gunpowder gas pressure parameter in the process of cluster munitions scattering.Firstly,the internal trajectory mathematical model of the cluster munition scattering is established by analyzing the mechanical structure and dispersion process of the center tube bursting-type cluster munitions.we calculated the theoretical value of the propellant gas pressure on the shrapnel scatters.Secondly,based on the new concept dynamic test theory,according to the requirements of the test environment and the test task,the overall scheme of the pressure parameter test system in the process of scattering is established,the technical indexes of the system are determined.The final system was developed for Cluster Munition Dispersing gas pressure measurement design.The tester consists of a front-end sensor,a charge amplifier,a transient waveform recorder(built by a logic control module)and a mechanical housing.It is the core unit of the test system,with low power consumption,modular,programmable parameters and other advantages.Finally,the test system was calibrated by the drop hammer calibration device,and the system sensitivity was determined.The test data provide the basis for the development and analysis of the center tube bursting-type cluster munitions. |
