Synthesized CAD Methods for Combat Vehicle Survivability Analysis
Abstract
To support its Army role in Vulnerability/Lethality analysis, the Ballistic Research Laboratory (BRL) has developed a suite of computer tools called (BRL-CAD) to assist in the generation, validation and interrogation of military geometry. Originally targeted to the support of vulnerability and nuclear survivability codes, these methods now also support many signature models, including some developed at TACOM/Keweenaw Research Center, Environmental Research Institute of Michigan (ERIM), Georgia Tech Research Institute, Northrop, and others. In this paper, the use of these tools is demonstrated. An Armored Fighting Vehicle (AFV) of the class being considered in the Armored Systems Modernization (ASM) program is used to show (1) how the input geometry is generated and (2) how various analysis codes are utilized in order to understand some of the performance issues affecting survivability. A candidate AFV is molded geometrically and various images are generated to check the design. An estimate of system weight is performed. Next a series of ballistic vulnerability and signature computations are applied to the design, demonstrating the kinds of metrics which can be derived in an analysis cycle.
