Calculation of Blast Loading in the High Performance Magazine with AUTODYN-3D
Abstract
The High Performance Magazine (HPM) is being developed by the Naval Facilities Engineering Service Center (NFESC) to reduce the land area encumbered by Explosive Safety Quantity Distance (ESQD) arcs and improve the efficiency of weapons handling operations. In the past, testing has been required to obtain verification and acceptance of designs to prevent sympathetic detonation. Due to the numerous possible configurations and ordnance storage layouts, the development and verification of prediction models is critical. AUTODYN-3D, a non-linear dynamics software program, is used to calculate the detonation of various configurations of stored ordnance in the Certification Test Structure. AUTODYN models the initial detonation, blast, and loading on the surrounding structures providing a detailed time-dependent three-dimensional view of the accident scenario. Pressure and impulse histories at selected locations as well as structural displacements and velocities are shown. Advantages and limitations of the numerical methods utilized within AUTODYN-3D are discussed.
