The split Hopkinson pressure bar and light gas gun as the two common means of dynamic loading are widely used in dynamic mechanical characteristics of many materials, while it can not meet the experimental study requirements of the concrete and reinforced concrete because of the small loading samples dimensions. To solve this problem, a simple large-dimension explosive loading assembly, which directly drive the flyer devised cone shape to achieve a large-dimension loading, was presented. Numerical simulation was first used to complete the design optimization of experiment conception. The dynamic process which an explosion drove the flyer was simulated based on ALE and Lagrange coupling methods. Then target range experiments were performed and the flyer flatness was measured by using self-made concentric pins, pulse networks and two oscilloscopes. The improvement was proposed prepared for the finally dynamic experiments of the large-dimension concrete and reinforced concrete samples.

尽管分离式Hopkinson压杆(SHPB)和轻气炮作为较为常用的两种动加载手段已经被广泛应用到多种材料的动态力学特性研究之中,但由于其自身加载试件尺寸较小,难以满足真实的混凝土和钢筋混凝土的实验研究需要。为解决该问题,提出了一套大尺寸简易爆炸加载装置,将飞片设计为锥形,利用炸药直接驱动飞片,实现大尺寸加载。先用数值模拟完成对爆轰加载装置的初步设计和优化,通过模拟炸药驱动飞片的动力过程,给出飞片和药柱的优化尺寸;然后利用自制的同轴探针、脉冲形成网络和两台示波器进行靶场实验测定,研究飞片平面度,提出改进方案,最终为大尺寸混凝土和钢筋混凝土试件的动态加载实验做准备。

尽管分离式Hopkinson压杆(SHPB)和轻气炮作为较为常用的两种动加载手段已经被广泛应用到多种材料的动态力学特性研究之中,但由于其自身加载试件尺寸较小,难以满足真实的混凝土和钢筋混凝土的实验研究需要。为解决该问题,提出了一套大尺寸简易爆炸加载装置,将飞片设计为锥形,利用炸药直接驱动飞片,实现大尺寸加载。先用数值模拟完成对爆轰加载装置的初步设计和优化,通过模拟炸药驱动飞片的动力过程,给出飞片和药柱的优化尺寸;然后利用自制的同轴探针、脉冲形成网络和两台示波器进行靶场实验测定,研究飞片平面度,提出改进方案,最终为大尺寸混凝土和钢筋混凝土试件的动态加载实验做准备。

The split Hopkinson pressure bar and light gas gun as the two common means of dynamic loading are widely used in dynamic mechanical characteristics of many materials, while it can not meet the experimental study requirements of the concrete and reinforced concrete because of the small loading samples dimensions. To solve this problem, a simple large-dimension explosive loading assembly, which directly drive the flyer devised cone shape to achieve a large-dimension loading, was presented. Numerical simulation was first used to complete the design optimization of experiment conception. The dynamic process which an explosion drove the flyer was simulated based on ALE and Lagrange coupling methods. Then target range experiments were performed and the flyer flatness was measured by using self-made concentric pins, pulse networks and two oscilloscopes. The improvement was proposed prepared for the finally dynamic experiments of the large-dimension concrete and reinforced concrete samples.
