摘要
通过设计排布在圆柱壳体周围的柔爆索的间距及柔爆索与圆柱壳体间的距离 ,得到了沿圆柱壳体周向呈余弦分布的冲量载荷 ,并设计了柔爆索加载的结构响应实验装置 ,对圆柱壳体的动态力学响应进行了实验研究。测得的圆柱壳体残余变形局限于± 70°左右的范围 。
By designing the spacing between the mild detonating fuse(MDF) strands and the standoff distance from the strands to the shell, the impulse with a nearly cosine distribution is obtained around the shell, and the experimental device for studying the structural response of cylindrical shells under MDF impulse loading is designed, then the experiments of structural response of cylindrical shells is carried out. The measured residual deformation of the shells is located between about ±70° and the maximum radial compression occurred along the 0° direction.
