SPH算法在长杆弹侵彻多层间隔靶中的应用

基于Autodyn软件,应用SPH算法对长杆弹高速侵彻多层间隔金属靶板的过程进行数值模拟,分析了弹体侵彻靶板后的剩余速度、剩余动能、以及形成的破片及其飞散情况,同时模拟初始速度及弹体质量对侵彻过程的影响.通过与实验结果的比较,表明数值模拟的结果是合理的,能够准确模拟长杆弹对多层间隔靶的高速侵彻过程,对预测弹体侵彻件能以...

Smoothed particle hydrodynamics algorithm applied in numerical simulation of layered metal targets impacted by long-rod projectile

A long-rod projectile penetrating layered metal targets was numerical simulated by using Autodyn program based on the meshfree SPH method.The residual velocity and kinetic energy after the projectile penetrating into the first target were analyzed,and the fragments were obtained.The effect of different initial velocity or mass on penetration was discussed.The simulated results were compared with the experimental ones.It is shown that the simulated results are reasonable and they can exactly reflect the pene...
