为了得到线性爆炸成型弹丸(LEFP)的预期形状,运用灰度理论和二次规划算法优化了线性装药战斗部的几何结构,建立了针对线性装药结构优化的灰度理论与二次规划算法组合模型。将线性装药视为装配体,药型罩、外壳以及炸药为具有相互配合关系的组件,用灰度理论对每个组件以及每个组件的几何特征进行权重计算,通过二次规划算法构建包含所有组件的目标函数。以某小型几何特征线性装药为例,用灰度理论与二次优化的组合模型所得的数值计算结果验证了优化线性装药几何结构的有效性。
To obtain expected shape of the linear explosively formed penetrators (LEFP), the geometrical structure of linear shaped charges warhead was optimized using the grey theory and the sequential quadratic programming al- gorithm. A combination model of grey theory and sequential quadratic programming algorithm for optimizing the structure of linear sharped charge was established. The linear sharped charge was regarded as an assembly, and lin- er, case and explosive as modules with mutual cooperation relationship. The weight of each module and its geomet- rical size characteristics were computed using the grey theory. The objective function which includes all module was built through the sequential quadratic programming algorithm. The effectiveness to optimize the geometrical struc- ture of charges was validated via numerical calculation results obtained by a combination model of grey theory and sequential quadratic programming algorithm, choosing the charges with a small geometric {eature as an example.
