摘　　要：为研究多层钢靶板侵彻环境下半导体桥火工品力学过载特性,通过LS-DYNA建立侵彻弹对不同排列状态3层钢靶的侵彻过程仿真模型,分析弹内半导体桥火工品壳体长度、壳体直径和药柱长度变化与靶板排列顺序、靶板间距和侵彻角度等侵彻环境的关系。结果表明:厚靶在两层薄靶中间时火工品轴向过载较小;靶间距为0~1倍弹长时,随着靶板间距增大,火工品轴向过载增大;侵彻角度在0~20°时,随着侵彻角增大,火工品承受过载减小。In order to study the mechanical overload characteristics of semiconductor bridge detonator under the penetration environment of multi-layer steel target,the simulation model of the penetration process of the three-layer steel target in different states was established by use of LS-DYNA.The relationships between the change of shell length,the shell diameter,the charge grain length and the target plate arrangement order,the target plate spacing,the penetration angle were investigated.The results show that:when the thick target is in the middle of two thin targets,the axial load of the detonator is small;when the target spacing is 0~1 times projectile body,with the target spacing increases,the axial load of detonator increases;when the penetration angle is between 0°and 20°,as the angle of penetration increasing,the detonator is less overloaded.
