弹丸侵彻装甲钢板过载特性数值模拟

Numerical Simulation of Overload Characteristics When Projectile Penetrating Armored Steel Plate

利用LS-DYNA3D软件,研究了弹丸侵彻装甲钢板的过载特性,针对几种典型的弹丸初速度、着角以及靶板厚度进行了模拟计算,得到了各种条件下的弹丸侵彻加速度过载曲线,分析结果表明着速、着角及靶厚对侵彻过载有很大影响,为硬目标侵彻引信的设计及装甲防护技术提供了参考。

The overload characteristics when projectile penetrating armored steel plate was simulated using LS- DY- NA3D. Based on typical penetration velocity, impact angle and steel thickness, calculation was conducted,, and the corresponding acceleration-time curves of projectile were obtained. The simulation results indicate that impact velocity, impact angle and steel thickness are influential in penetrating overload, and the simulation results can be referred to hard target penetrating fuze design and armored protection.
