Simuliation Software Design of Gun Interior Ballistics

摘要

Calculation and simulation of interior ballistics is the fundament of the design of gun and projectile. The function of interior ballistics calculation is to determine the maximum pressure of combustion chamber, the peak acceleration and the muzzle velocity of projectile based on the gun-propellant-projectile parameters given. The simulation software of interior ballistics firing environment is developed by adopting lumped-parameter numerical model and using Matlab/Simulinlc? programming environment. This software includes mainly four parts: the input module of parameters, the calculation module of shape function, the calculation module of lumped-parameter model and the output module of data and drawing. The function of this software not only help designer to calculate interior ballistic parameters(mean pressure, velocity of projectile and gas temperature, et al.) according to propellant charge construct, and optimize gun construct and charge design(propellant grain parameters) according to technical target. The simulation software is very suitable the initial stage design of the gun, propellant and projectile.
