摘要

为了研究爆轰不对称性对线性聚能装药侵彻性能影响,运用有限元软件LS-DYNA,采用正交设计实验,选取起爆偏移量、药型罩壁厚、装药高度三种因素,对线性聚能装药侵彻45钢靶板的过程进行仿真,以侵彻靶板的深度为评估依据,通过毁伤效果分析得到三种因素对毁伤评估标准的影响权重;通过对相同水平下不同截面形状药型罩的线性聚能装药在不同起爆偏移量下侵彻45钢靶板的过程进行仿真分析,进一步得到弧顶锥形线性聚能装药、截顶锥形线性聚能装药、半球形线性聚能装药在不对称爆轰波作用下的侵彻性能以及抗偏心能力。研究结果可为线性聚能装药在工程应用方面提供一定的参考。

Abstract

In order to study the influence of detonation asymmetry on the penetration performance of linear shaped charges,the finite element software LS-DYNA was used and orthogonal design experiments were adopted.Three factors,namely detonation offset,liner thickness and charge height,were selected to simulate the process of linear shaped charge penetrating 45 steel target plates.The depth of penetrating the 45 steel target plate was taken as the evaluation basis.Through the analysis of the damage effect,the influence weights of three factors on the damage assessment criteria were obtained.Through the simulation analysis of the penetration process of linear shaped charge of different cross-sectional liner penetration into 45 steel target plates at the same level under different detonation offsets,the penetration performance and anti-eccentricity ability of arc top conical linear shaped charge,truncated top conical linear shaped charge and hemispherical linear shaped charge under the action of asymmetric detonation waves were further obtained.The research results can provide certain references for linear shaped charge in engineering applications.
