穿甲爆破弹引信对薄弱目标的灵敏度分析

Fuze Sensitivity Analysis of Armor-piercing High-explosive Projectile Impacting Vulnerable Target

针对穿甲爆破弹引信对薄弱目标的灵敏度难以考核的问题，提出了基于Multiphysics／LS-DYNA与ADAMS的联合仿真方法，分析了穿爆弹碰击45。钢薄靶情况下引信惯性触发机构灵敏度问题。试验及仿真结果对比表明，250m/s着速下弹丸引信喷性触发机构对4～8Hml厚45”钢靶有足够灵敏度，满足穿爆弹引信对薄弱目标的作用性能要求。

The sensitivity of semi-ain.t-pierced projectile fuze impacting vulnerable target is difficuh to be verified. Ai- ming at this problem, a joint simulation method on the basis of Multiphysics/LS-DYNA and ADAMS was proposed to an- alyze the sensitivity of fuze inertia initiation mechanism of projectile impacting 45 # target. The comparison between test and simulation results indicated that, on the condition of 250m/s impacting velocity and 4mm--8mm target thickness, the fuze inertia initiation mechanism had enough sensitivity, which could satisfy the performnce requirement of armor-piercing high-explosive projectile fuze impacting vulnerable target.
