摘　　要：C型结构固体电枢结构参数直接影响到电磁轨道炮的发射,针对此问题,提出了一种基于数值分析的C型电枢机构优化方法,该方法采用正交试验设计样本数据,基于响应面法构造优化函数,采用遗传算法进行极小值优化,获得了最大电流密度值的极小值。数值模拟实验表明:该方法降低了电流密度峰值,降低了转捩发生的可能性,具有较高的准确性和可行性,能够为电枢结构改进提供有效途径。The structural parameters of the C-shaped solid armature affect directly the emission of electromagnetic rail gun.Aiming at this problem,a structural optimization method for the C-shaped armature was proposed based on numerical analysis.The proposed method employs the orthogonal experiment to design sample data,and the optimization function was constructed based on response surface method.The genetic algorithm was used to get the minimum.The minimum value of the maximum current density was obtained.The simulation experiments show that the method reduces the peak current density and the possibility of transition in higher accuracy and feasibility.It provides an effective way to improve the armature structure.
