摘　　要：利用ANSYS/LS-DYNA建立了370 mm口径钻地弹侵彻发射井钢筋混凝土上盖的数值计算模型,完成了钻地弹对上盖侵彻过程的数值计算,获得了侵彻速度、应力、应变等瞬动结果,预估了钻地弹的侵彻特性及上盖的抗毁伤性能。研究所采用的模型、参数及结果能较为准确的反映钢筋混凝土上盖在侵彻作用下的破坏过程,为发射井上盖的防护性能研究提供重要参考。The numerical calculation model of the penetration of the upper cover of the launch shaft by a 370 mm caliber drilling projectile was established by ANSYS/LS-DYNA,and the numerical calculation of the penetration process of the upper cover by the drilling projectile was completed,and the transient results of the penetration velocity,stress and strain were obtained,which predicted the penetration characteristics of the drilling projectile and the anti-damage performance of the upper cover.The model,parameters and results used in the study can reflect the damage process of the reinforced concrete cover under the intrusion more accurately,and provide an important reference for the study of the protective performance of the launch shaft cover.
