摘要

聚能装药因其能量利用率高,在未爆弹药销毁领域应用广泛。为实现水下未爆弹药的安全高效销毁,对组合式Φ50mm聚能装药射流水中引爆厚壳装药能力的影响因素进行了研究。针对喇叭形药型罩,分析装药结构、头部组合式空腔结构长度、水深等因素的影响,采用数值模拟方法表征聚能射流水中成形特性,并评估其引爆能力。结果表明:药型罩高度、壁厚、曲率半径以及药柱高度等参数,对聚能射流引爆能力的影响程度存在强弱排序;对于水下聚能装药,组合式空腔结构射流的能量损耗降低了74.8%;随机森林模型可有效预测射流与带壳装药接触速度随水深增加的非线性变化规律。研究成果可为水下聚能装药结构优化与工程实践提供理论依据与技术支撑。

Abstract

The shaped charge is widely used in the field of unexploded ordnance destruction disposal due to its high energy utilization rate.For the safe and effective disposal of unexploded ordnance in water,this paper investigates the factors influencing on the underwater initiation capability of jets.Numerical simulation methods are employed to characterize the jet formation process of two charge structures in water.Focusing on the flared liner shaped charge structure,the effects of the charge structure,the length of the combined cavity structure at the head,and the water depth on the initiation capability of the shaped charge jet are analyzed.The results indicate that the flared liner charge structure affects the jet’s initiation capability in the following order of significance:liner height,liner thickness,explosive column height,and liner curvature.The combined cavity structure significantly reduces the energy loss of the jet by 74.8%.The Random Forest (RF) model effectively predicts the nonlinear variation characteristics of the contact velocity between jet and shelled charges in water with the increase in water depth.

Key words： shaped charge; jet initiation; numerical simulation; orthogonal optimization design; Random Forest model
