Abstract

Abstract

Using mild detonating fuse(MDF) impulse simulating the X-ray blow-off impulse in studying the structural response of cylindrical shells, it is needed to measure the distribution characteristics of MDF impulse. According to the optimized results， an array of MDFs is arranged around a cylindrical shell, the MDF impulses at several angles around the circumference of the cylindrical shell are measured. The measured impulses indicate that a nearly cosine distributed impulse around the circumference can be obtained by designing the space between the MDF strands and the standoff distance from the strands to the shell.
