Abstract
In order to maintain a safe and reliable blast tube facility, certain structural components of the tube, which are subjected to intense loading conditions, must be analyzed for any structural weaknesses which may lead to catastrophic failure. The fact that the highest overpressures are generated in the driver section warrants a structural analysis of those components which make up this section of the blast tube. Such components include the endplate which bears the full axial impulse of the fuel-air explosion and the 1.8 meter diameter steel tube which radially confines the expanding gases. The paper reports on the results of a finite element model structural analysis used to study the response of the above mentioned components. Also included is the selected optimum modified endplate design which will replace the present endplate used on the blast tube.
