Abstract:
A key technology problem with respect to approval testing is that of simulating firing impulse in large
calibre weapon systems without firing live ammunition with many problems as high cost, strict
environmental conditions, large numbers of staffing, wide test field, etc. There are two main methods in use
at present: the first method is to carry out numerical simulation of gun firing dynamics with modelling and
simulation (M&S) technology; the second method is to conduct hardware-in-the-loop simulation test with
firing impulse simulator (FIS). The latter types of methods generate impulse effect to simulate gun live
firing from power sources of gunpowder, gas, or liquid. FIS with gunpowder or gas as power source take on
problems as low control precision, complicated operating process, and poor safety. In this paper, a FIS
which transfer test data via CAN (Control Area Net) bus was designed and developed. System composition
and working principle are introduced based on analyzi
ng features of similar products, where key
technologies as counter-recoil analysis, mass and speed choice of pounding head, system safety design are
studied with emphasis. The research results indicate that FIS can be used as an effective supplementary to
live firing in approval test of weapon system.
