摘    要:影响射孔穿深的因素很多,通过试验和计算机数值模拟的手段,着重分析、讨论混凝土靶材物性因素(靶等效应力强度、声阻抗和孔隙度、砂粒度)的影响.结果表明侵彻初期及随后的定常侵彻阶段主要影响因素是声阻抗、孔隙度侵彻滞止阶段主要影响因素是动态抗压等效应力强度砂子粒径是影响射孔侵彻深度的重要因素.

关 键 词:射孔  侵彻深度  混凝土靶

Abstract:Various factors affect perforation penetration. The physical factors such as equivalent stress strength, acoustic impedance, porosity and sand grain size of concrete target materials on the penetration are analyzed and discussed by testing and computer numerical simulation. The results show that acoustic impedanee and porosity are the main influencing factors during the initial and the following steady penetrating period. Dynamic equivalent compression stress strength is mainly influencing factor during the penetrating-stagnation period. Sand grain size is the main effect factor on perforation penetration depth.
Keywords:perforation  penetration depth  concrete target
