Embodiment

[0050] Please refer to figure 1 with figure 2 , figure 1 Shown is a schematic diagram of the overall structure of the chamber pressure measuring device described in the embodiment of the present invention; figure 2 Shown is a schematic cross-sectional structure diagram of the chamber pressure measuring device according to the embodiment of the present invention.

[0051] This embodiment provides a gas gun bore pressure measuring device, which includes a sealing assembly, a measuring assembly and a counterweight base 2 connected end to end in sequence. The measuring assembly is composed of a piezoelectric ceramic 1 and auxiliary components connected with the piezoelectric ceramic 1 . The sealing assembly is used to seal one end of the high-pressure air chamber of the gun barrel, which can receive the pressure given by the gas cannon and transmit this pressure to the piezoelectric ceramic 1. The piezoelectric ceramic 1 transmits corresponding data through auxiliary component...

Abstract

The invention provides a small-caliber gas gun bore pressure measuring device and a using method thereof and relates to the field of parameter measurement of a trajectory in a gas gun. The small-caliber gas gun bore pressure measuring device comprises a sealing assembly, a measuring assembly and a balance weight base piece which are connected end to end in sequence; and the measuring assembly is composed of piezoelectric ceramic and an auxiliary component connected with the piezoelectric ceramic. According to the small-caliber gas gun bore pressure measuring device, the defects of complex structure, large size, high manufacturing cost, poor program adjustability and measurement stability, unsuitability for measuring the gun bore pressure of small-caliber gas guns and the like of the priorart of gun bore pressure measurement can be effectively overcome.

Description

technical field [0001] The invention relates to the field of parameter measurement of the internal ballistic of a gas cannon, in particular to a small-caliber gas cannon bore pressure measuring device and a method for using the same. Background technique [0002] The parameter measurement of the internal ballistic of the gas cannon is an important basis for the design, fault diagnosis and structural optimization of the gas cannon. Chamber pressure is an important parameter to characterize the internal ballistic characteristics of gas cannons. Accurately obtaining the chamber pressure curve during projectile launch has important guiding significance for the reliability research of gas cannon strength and the optimization of gas cannon system parameter design. [0003] At present, there are two common chamber pressure measurement methods: one is the mechanical pressure measurement method, which mainly uses copper pillar pressure measurement. [0004] The method utilizes the p...
