Abstract

A drop hammer impact failure experiment was carried out on a schematic experiment article designed as the model of a simplified rocket(missile) interstage bolt flange connection structure.The time-history response data of the bolt force,impact force and impact velocity of drop weight, stress at the key point of cylinder wall and slot displacement of the connecting structure were collected.The article was also simulated numerically by using the Abaqus finite element software.The results show that the failure characteristics of the connection structure under transverse impact load are sequential failure, and the three bolts on the upper half part of the bolt distribution plane are the initial failure bolts.On this basis, the working strength of the connection structure was determined.The comparison between the experimental and simulation data shows that the simulation model has good calculation accuracy.The results provide a reference to the impact strength design of rocket(missile) body connection structures. 
