Design of Firing Impulse Simulator and Analysis of Its Key Research and Development Technologies

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 (MS 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 analyzing 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.
