An analysis-driven approach is needed which compares and qualifies designs for new or modified submarine mechanical components under extreme loadings against those of existing shock qualified components. Such an application must provide a comparison process of component attributes through an automated capability while leveraging a digital environment qualification through finite element analysis. Analysis of shock worthiness of new or modified components may then be deduced through a comparison that accounts for ranges of potential differences in component physical attributes, mounting conditions, and orientations. An ontology database and rules provide the perfect match for the needs of component property comparison as they allow for the automatic inference of differences, similarity qualification, and range of differences scoring. The ontology is a database format that captures domain concepts in a hierarchal format while capturing the relationships and similarity between concepts. These will provide a first level of component attribute comparisons. A second finite element analysis of physical differences of high load stresses will be accomplished through both ontology rules and data integration with finite element analysis tools used by the Navy and innovative alternatives such as Progeny?s biometrical facial recognition capability for analyzing differences in graphical plots currently familiar to Navy component designers.
