Research On Overpressure Test System Of Gunshot And Muzzle Blast Wave

The overpressure test of gunshot and muzzle blast wave is important in the type tests of conventional weapon. It plays an important role in studying,designing,identifying,protecting the guns and weapons. This paper researched a overpressure test method of gunshot and muzzle blast wave based on the storage testing technology and wireless sensor network technology.According to the characteristics and difficulties of gunshot and muzzle blast wave test, the main work of this paper is as follow:Firstly, the related literature about the explosion shock wave testing and gunshot and muzzle blast wave test are extensively retrieved at home and abroad in order to determine the research content of the paper. Then the theory and the signal characteristics of bouche shock wave is analyzed and the key technology in overpressure test of gunshot and muzzle blast wave is studied. Finally, the dynamic characteristics of system are obtained by the shock tube dynamic calibration testing and the reliability of the method is validated by the shooting range test.In combination with theoretical analysis engineering design,lab and the shooting range test, the innovative research of overpressure test method of gunshot and muzzle blast wave is organized as follows.(1)From the mechanism and the propagation theory of gun flow field, the time domain, frequency domain characteristics of bouche shock wave signal are analyzed.The overpressure test characteristics of the gunshot and muzzle blast wave are summarized.The extensibility theory and test of the projectile warheads shock wave is studied. (2) The key technology of overpressure test of bouche shock wave is researched, which includes intelligent power management module, signal conditioning module, data storage module, wireless communication module, U disk storage module. The scheme of overpressure test of bouche shock wave is designed.(3) After the shock tube dynamic calibration test system,two test plan are designed. They are a muzzle blast wave overpressure test of the vehicle-mounted guns and a muzzle blast wave overpressure test of7.62mm rifle.
