摘要: 为获得串联战斗部随进弹在受到前级装药爆炸作用时，质量对其所受最大过载及动能衰减的影响规律，采用非线性动力学软件AUTODYN，基于Euler-Lagrange耦合算法，对前级装药的爆炸过程中，不同弹径、不同质量的随进弹穿越爆轰场进行了数值模拟。得出了随进弹在前级爆炸作用下所受最大过载和动能衰减的变化规律。基于数值模拟结果建立了随进弹剩余速度与质量的无量纲关系式，计算结果得到了实验验证。Abstract: The explosion of shaped charge of tandem warhead and the impact process on followed projectile of impulse are simulated with a numerical hydrocode of AUTODYN. The maximum acceleration response and kinetic energy attenuation of followed projectile during impact process are analyzed under different projectile mass and diameter. The result indicates that the projectile's maximum acceleration decreased, remainder kinetic energy increased with followed projectile mass increased. An equation of followed projectile's residual velocity with projectile mass is concluded based on simulation results, and it is validated by experimental results.
