| Abstract: |
A database-driven approach is needed which characterizes the failure modes of the mechanical components of submarine systems under extreme loadings. Such an application must provide automation of the component shock qualification process through an automated capability while providing component-level qualification based upon similarity of components and failure modes. Certification of shock worthiness of new components may then be deduced through an "extension" process (in which new components that are similar in physical aspect, shipboard installation and intended use, to a previously "qualified" component) and may be certified based upon the certification of those similar components. Leveraging rules with a software reasoner allows for the automatic generation of new facts such as certification through the extension process. |
| Benefits: |
The results of this approach will have direct benefits to organizations requiring certification and metrics of shock hardening of components against the Navy's shock hardening program levels. The creation of a database that captures these results will provide a sharable resource through the Navy. Automation of the certification "extension" program will diminish the time and budget required to certify a new component's shock worthiness by qualifying it through the results of previously certified components. This will include savings through the reduction of personnel time involved in MIL-S-901D mandated shock testing tasks such as post-testing inspection of tested items for shock-induced defects and the required re-testing of components performed for the purpose of developing suggestions for corrective design modifications. Additional funding benefits will be realized through the reduction of costs of the MIL-S-901D use of commercial facilities for testing as well as the acquisition and shipping costs of items to be tested. Finally, an automated capability will decrease the need for the staffing and physical resources required to perform certification and analysis. |
