    摘要:

    針對迫擊炮內彈道參量在優(yōu)化設計中存在的效率低、全局搜索性差、過(guò)程復雜等問(wèn)題,基于迫擊炮內彈道模型,提出了一種過(guò)程集成優(yōu)化設計方法。首先利用MATLAB/Simulink軟件搭建了迫擊炮內彈道模型并通過(guò)仿真計算得到迫擊炮的膛壓、速度隨時(shí)間變化曲線(xiàn),得到的膛壓和速度參量與試驗結果具有較好的一致性。然后通過(guò)集成優(yōu)化平臺ISIGHT集成MATLAB/Simulink軟件,結合帶精英策略的改進(jìn)非支配排序遺傳算法對其進(jìn)行了以最大膛壓和炮口速度為目標函數的多目標優(yōu)化設計。優(yōu)化結果表明:優(yōu)化后的最大膛壓降低了13.63%,炮口速度提高了10.46%,該方法在提升內彈道性能的同時(shí)提高了優(yōu)化效率,為武器的內彈道優(yōu)化設計提供了一種新思路。

    Abstract:

    Aiming at the problems of low efficiency, poor global search and complex process in optimization design of internal ballistic parameters of mortar, a process integrated optimization design method was proposed based on the mortar interior ballistic model. Firstly, MATLAB/Simulink software was used to build the mortar interior ballistic model and the mortar bore pressure and velocity curve with time were obtained through simulation calculation. The obtained bore pressure and velocity parameters were in good agreement with the test results. Then, through the integration optimization platform ISIGHT integrated with MATLAB/Simulink software, combined with the improved non-dominated sorting genetic algorithm with elite strategy, a multi-objective optimization design with the maximum bore pressure and muzzle velocity as the objective function was carried out. The optimization results show that the maximum bore pressure is reduced by 13.63% and muzzle velocity is increased by 10.46% after optimization. This method not only improves the performance of interior ballistics but also improves the optimization efficiency, which provides a new idea for the optimization design of weapon interior ballistics.
