Described is a NASTRAN finite element near-miss shock response simulation of a Vertical Launch Antisubmarine Rocket (VLA) missile carrying a Mk 54 torpedo. The numerical simulation represents an encanistered Mk 54 VLA missile in a launcher cell subjected to 'qualification level' shock. The finite element representation models the torpedo, airframe, rocket motor, canister, canister adaptor, and dog-down structure. Scaled acceleration time histories were enforced at the top of the canister and at the base of the canister adaptor. Vertical inputs were scaled from acceleration data recorded aboard USS Mobile Bay (CG 53) during the 1987 shock trials. Lateral inputs were scaled from acceleration data recorded aboard the standard floating shock platform (FSP) during the 1992 barge shock tests of an SM-2 Block IV missile. Shock inputs were applied to the finite element model (FEM) at canister support points. Missile loads were predicted and compared with VLA allowable loads. Shock response spectra (SRS) were predicted at critical missile locations and compared to those from the ship shock trials. Survivability of the Mk 54 VLA missile when subjected to these qualification level shock conditions aboard ship was predicted.
