An internal ballistic chamber pressure signal generator for virtual experiment of gun firing

Abstract

The invention provides a signal generator about the internal ballistic pressure for the virtual experiment of the gun firing, which comprises a mount body. The mount body is provided with an external power input port, a data input port and an analog voltage output port. The digital signal processor and the digital-to-analog conversion module are arranged inside the mount body. The digital signal processor comprises a DSP module and a power conversion module. The power conversion module is connected with the external power input port. The DSP module is connected with the data input port. The digital-to-analog conversion module is connected with the analog voltage output port. The signal generator about the internal ballistic pressure for the virtual experiment of the gun firing establishes a channel between the virtual simulation system and the data acquisition instrument to convert the simulation calculation data into the analog voltage signal which can be collected by the acquisition instrument, which students are able to conduct the establishment of the virtual internal ballistic test system, the connection of the training line and the parameter setting of the data acquisition instrument. The signal generator about the internal ballistic pressure for the virtual experiment of the gun firing has the compact overall appearance with the simple and convenient operation.

Description

technical field [0001] The invention relates to a signal generator for simulating internal ballistic chamber pressure, in particular to a chamber pressure signal generator for a virtual experiment process of firing a gun. Background technique [0002] When the gun is fired, the gunpowder burns to generate greater pressure to push the projectile forward to obtain a greater exit velocity. Gun firing experiments usually install a pressure sensor on the barrel or gun barrel to test the change of chamber pressure over time. Weapon launching experiments are very dangerous. At present, many schools no longer conduct physical experiments, and usually only conduct virtual experiments through simulation software. Virtual simulation software generally only involves the calculation of chamber pressure data, and cannot simulate the construction of equipment and instruments in the real test process and the parameter setting of the data acquisition system. Therefore, students cannot intui...
