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.

Key words： linear shaped charge; numerical simulation; eccentric initiation; liner
