Study on Interval Optimization of Interior Ballistic of Large-Caliber Artillery
摘要
A research method of artillery interior ballistics uncertainty optimization based on interval optimization is proposed. Firstly, the classical interior ballistics model of large caliber gun is established, and then the uncertain vector is described in the form of interval, and the interval uncertain optimization model is obtained. Finally, the interval uncertainty model is transformed by the interval order relationship and interval possibility model. The optimization result is Pareto optimal solutions. Under the constraint of maximum breech pressure, the maximum muzzle velocity can be increased by about 7 m/s. The results obtained provide a reference for the optimization of interior ballistic performance of large caliber guns under the conditions of uncertainty such as propellant parameters.
