喇叭药型罩壁厚对杆式射流成型影响的数值模拟

Numerical Simulation of Thickness Influence of Horn Liner Bar Type Rod-Like Jet

为了对比分析喇叭形药型罩壁厚对杆式射流成型的影响,利用ANSYSY/LS-DYNA有限元分析软件,在战斗部装药结构相同的条件下,改变喇叭形药型罩的厚度;合理选择药型罩的厚度,有助于提高杆式射流的稳定性及其侵彻性能。

In order to comparatively analyze the influence of the thickness of horn liner to bar type rod-like jet modeling process, the rod-like jet was analyzed by using the ANSYS/LS-DYNA finite element analysis software. We changed the thickness of the horn liner under the same conditions of shaped charge. Selecting the thickness of liner reasonably is helpful to improve the stability and penetration performance of rod-like jet.
