RESPONSE OF A DOUBLE CANTILEVER FRAME SUPPORTED PIPELINE TO INTERNAL TRANSMITTED IMPULSIVE LOADS

摘要

This paper presents experimental results of the response of a double cantilever frame supported pipeline to internal transmitted impulsive loads generated by the propagation of shock, detonation and blast waves, with both open and closed end flange configurations. Time resolved axial displacement responses of specially constructed supports were obtained. These showed the coupling of the impulsive loads transmitted into the longer time scale support oscillations. This paper also reports on the comparison between numerical simulations of the response of the pipeline supports with the experimental results obtained.
