Calculation of Blast Loading in the High Performance Magazine with AUTODYN-3D

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