摘　　要：为了研究圆柱形爆炸容器在炸药爆炸作用下的变形过程,设计了电探针测量内部爆炸作用下钢筒变形的方法。采用数值模拟方法进行预估,在钢筒的中心进行了120g TNT和180g TNT当量球形装药下的爆炸加载实验,获得了爆炸不同时刻钢筒径向位移随时间的变化关系,电探针测量钢筒最大变形与实验后钢筒变形测量结果较好吻合。An electric probe measurement technique was proposed to measure the deformation underg- one by the ektexines of the cylindrical steel shells subjected to the detonation of spherical explosive charges inside them. Numerical simulation was carried out to forecast the deformation of the steel shell ektexine at the section of the explosion center in the case of the spherical high-explosive charge e- quivalent to 120 g TNT as well as 180 g TNT. Based on the above, the corresponding experiments were conducted. The radical displacements at the different times were obtained at the characteristic points for the ektexines of the cylindrical steel shells. The measured results by electric probes are con- sistent with the deformation of the cylindrical steel shell after the experiments.
