Projectile-Artillery-Propellant Coupled Optimization Design Method of Artillery Weapon Systems

The artillery weapon system is a complex system of great non-linearity. There are many factors and their coupling relationship affecting the firing performance of artillery, and the key factor positioning is difficult. How to improve the firing performance of artillery through optimization is a challenge. The current optimization method considers less coupling factors. To approach this challenge, a projectile-artillery-propellant coupled optimization design method is proposed, where a multidisciplinary coupling of projectiles, artillery and propellant is proposed and used to construct an optimization model, and the minimum initial disturbance is taken as the optimization objective. The simulation results show that at the moment when the projectile exist the muzzle, the optimized muzzle vibration displacement is reduced by 47.6%, the muzzle vibration speed is reduced by 33.4%, the average nutation angle is reduced by 63%, the average nutation angular speed is reduced by 27%.
