Software Development for Automation of Space- and Time- Varying Pressurization on Small Caliber Gun Barrels

Abstract

A console application program was developed to automate the process, starting from triggering IBHVG2 (Interior Ballistics of High Velocity Guns, version 2) execution on the fly for pressure calculation, determining pressure gradient along down-bore distance, parsing the LS-DYNA(TM) key word file for element extraction, associating load curves with selected elements, and finally generating a complete LS-DYNA key word file for explicit dynamic analysis. This report presents the architecture and process flows of the software design using the unified modeling language. The software development integrated IBHVG2 code with LS-DYNA program, greatly streamlining pressure data computation, transformation and application.
