【摘要】 该文提出了一种大长径比动能侵彻体侵彻钢筋混凝土的模拟试验方法,通过侵彻速度为300 m/s~400 m/s的57 mm动能侵彻弹对半无限厚钢筋混凝土靶的垂直侵彻试验,得到了最大侵彻深度、着靶姿态等试验参数。由侵彻钢筋混凝土的经验公式得到的最大侵彻深度数据与试验数据进行了对比,试验数据为反深层工事的毁伤机理和数字仿真研究提供依据,同时通过毁伤效应的试验研究,为找到一条高效毁伤典型深层工事的方法提供条件。更多还原

【Abstract】 A simulative experimental method of big length-radius ratio kinetic penetration bodies against reinforced concrete targets is proposed.Through a vertical penetration experiment against half-infinite-thick reinforced concrete targets with the 57 mm kinetic penetration projectile whose speed ranges from 300 to 400 m/s,the maximal penetration depth,hitting posture and other experimental parameters are obtained.The data acquired this way are compared with the data acquired through the experimental formula and they are basically identical.Those experimental data provide basis for the studies on the damage mechanism and the numerical simulation against the thick project.At the same time,through experimental studies on the damage effects,a method of damaging typical thick-project is found.更多还原
