Implementation Of Interior Ballistics Test System Based On The VXIbus

Interior ballistics is the study of the passage of the bullet within the gun barrel. There is no denying the fact that initial velocity and chamber pressure are important parameters to interior ballistics which greatly effect weapon performance. The interior ballistics test includes a lot of data calculation and processing. According to modern test requirement, it is impossible mission to traditional way because of great disadvantages, such as low reliability, poor efficiency and unfriendly user interface and so on. Especially, the experiment of interior ballistics has got more complex for recent years, the new demands of the system are put forward, so the new requirements can't be carried out with traditional way.The task comes from a graduate school of China North Industries Group Corporation. According to test requirement, an interior ballistics test scheme of design and implement based on VXIbus high speed data acquisition module and virtual instruments development platform are brought forward. VXIbus (VMEbus Extension for Instrumentation)is a standard bus. It not only inherits the characteristic of GPIB instruments and VMEbus, but also possesses lots of outstanding advantages, such as high reliability, high speed, mass data throughput, modularization, flexible integration. In fact, it has been become an excellent test platform. The modern computer combines with communication and measurement...
