摘　　要：为了研究不同质量G45钢破片对中大口径弹药壳体侵彻效应,利用有限元分析软件ANSYS/LS-DYNA建立破片侵彻壳体模型。将弹药壳体通过等效公式换为Q235钢板,开展了在不同速度下,不同质量G45钢破片侵彻等效靶板Q235钢数值模拟仿真。仿真分析结果表明:相同质量下,G45钢破片撞击靶板侵彻深度与侵彻直径随着速度增加呈现递增趋势;得到了4.7 g,9.8 g小质量G45钢破片在800~1800 m/s速度范围内无法有效穿透中大口径弹体等效靶的结论;19.5 g G45钢破片侵彻20 mm的中大口径弹体等效靶的极限穿透速度范围在1200~1400 m/s之间。The shell model of fragment penetration is built by finite element analysis software ANSYS/LS-DYNA to study the penetration effect of G45 steel fragments with different qualities on medium and large caliber ammunition shells.The ammunition shell is changed into a Q235 steel plate by the equivalent formula,and numerical simulations of the penetration of the equivalent target plate Q235 steel by G45 steel fragments with different qualities at different speeds are carried out.The simulation results show that under the same mass,the penetration depth and diameter of G45 steel fragments impinging on the target plate increase with the rising velocity.The small mass G45 steel fragments of 4.7 g and 9.8 g cannot penetrate the equivalent target of medium and large caliber projectiles in the velocity range of 800–1800 m/s.The limit penetration velocity of 19.5 g G45 steel fragment penetrating the equivalent target of 20 mm medium and large caliber projectiles is between 1200 and 1400 m/s.
