摘要:
为研究高强度钢杆弹侵彻低强度钢靶板的侵彻规律,运用AUTODYN动力学软件对35CrMnSiA杆弹在1.0~1.8 km/s着速下对A3钢半无限靶的侵彻过程进行了仿真和实验研究。数值模拟和实验分别采用动力有限元-光滑粒子动力学(FE-SPH)耦合算法和侵彻深度(DOP)方法进行。计算及实验结果的一致证明了FE-SPH耦合算法在该文工况下的适用性。研究表明,高强度钢弹侵彻低强度靶的过程分为破碎侵彻和刚性侵彻2个阶段,侵深随着速单调非增而剩余弹长随着速单调递减。
Abstract:
To analyze the law of high strength steel projectile penetrating low strength steel target,the numerical simulation and experiment on long-rod 35CrMnSiA projectiles with the velocity of 1.0~1.8 km/s penetrating into infinite thickness A3 steel targets with hydro-code AUTODYN are presented here.The finite element-smoothed particle hydrodynamics(FE-SPH) coupling method and the depth of penetration(DOP) method are applied in the simulation and experiment.The numerical predictions of depth of penetration and the residual length of projectile show good agreement with experimental observations,which shows good applicability to the high velocity penetration simulation.The results show the penetration processes can be divided into the fragments penetration and rigid projectiles penetration,and there is a rule of depth monotone non-increasing variation and residual length of projectile monotone decreasing variation with striking velocity.
