Computer Programs for Generation of NASTRAN and VIBRA-6 Aircraft Models.

Abstract

This report describes a series of computer programs designed to aid the analyst in preparing input data for aircraft models to be analyzed using NASTRAN and/or VIBRA-6. The programs permit creation of either beam or plate-type models of aircraft, subsequent postprocessing of NASTRAN OUTPUT2 files, and creation of VIBRA-6 AERO, IMOD and LOAD fixed data decks. In addition, the analyst may specify use of either the Ritz procedure or standard NASTRAN eigensolvers to derive normal modes of the aircraft for use in the VIBRA-6 vulnerability assessment. A command procedure is provided to orchestrate the execution of the various programs, to keep track of file assignments and to maintain a history of program use. Keywords: Blast response; Gust-loads; Nuclear explosions; Vibra-6 computer program; NASTRAN-computer program; Structural response.
