[0071] Example 1
[0072] Aiming at the inner ballistic process of artillery firing, the optimization algorithm of the present invention is used to optimize the parameters of the propelling charge and the structural parameters of the inner bore, so as to obtain a better inner ballistic design scheme. The optimized design variables include: propellant mass ω i , gunpowder thickness e i , gunpowder aperture d 0i , the length of gunpowder l ci , the chamber volume V of the inner chamber structure 0 , constitute the design variable vector X, where the subscript i=1, 2, i=1 represents thin powder, i=2 represents thick powder. The objective function is the muzzle pressure P at the end of the inner ballistic trajectory g , the charge utilization coefficient η ω , the working volume utilization coefficient η g . The constraint function is the projectile velocity V g , the maximum pressure P m , the relative position η of the end of gunpowder combustion k .
