Tuesday PM, November 19

1:00 - 3:00 PM: Shock & Vibration Requirements for Future Procurements - Moderator: Dr. Robert Sierakowski, Chief   Scientist, Air Force Research Laboratory for Munitions (Ballroom C)

This panel will examine current specifications used to design equipment and platforms to withstand Shock & Vibration environments. The discussion will explore the move towards commercial standards, use of COTS equipment, the proper role of M&S tools, and testing. The focus of the panel will be to explore the integration of these efforts to develop procedures to enable the shipyards to reduce costs and the Navy to demonstrate appropriate use of public funds and proper care of the environment. Members of the panel include Mr. Richard Taddeo, Director, Acoustic, and Standards Division, NAVSEA 05T, Mr. Robert Bowser, NAVSEA 05P3, Dr. Millard Firebaugh, Vice President of Innovation & Chief Engineer, General Dynamics Electric Boat Corporation, and Mr. Dave Williams, Vice President, Engineering,  Northrop Grumman Ship Systems.

3:20 - 5:20 PM: DDAM vs. Transient Analysis Panel - Moderator: Kevin Arden, Northrup Grumman Newport News, (Ballroom D)

This panel will discuss DDAM and transient analyses. One questioned often raised is why does anyone do DDAM anymore? DDAM and transient analyses are not mutually exclusive, there are legitimate reasons to use one or the other. This panel will debate when to use DDAM and when to use transient analyses. Topics to be covered include: the reasons each analysis method is used; the advantages of one over the other; the limitations of DDAM and how is the decision to use DDAM or transient analysis made; is DDAM conservative, if it is how does transient analyses help eliminate the conservatism or stated another way; is transient or DDAM inherently a better analysis/design tool than the other; does the availability of powerful computer codes, advances in computer technology and analytical correlation studies changed the credibility of DDAM; and are more transient analyses performed on submarines than surface ships?  Panel members are Fred Costanzo, NSWC-CD, Robert DeWoody, Northrup Grumman Ship Systems, Joel R. Griffin, Northrop Grumman Newport News, Dana Johnson, NAVSEA 05P4, George Camp, General Dynamics Bath Iron Works, Allen White, General Dynamics Electric Boat
 

5:40 - 6:40 PM: UNDEX Bubble Modeling Discussion Group - Leader: Dr. Jeff Cipolla, Hibbit, Karlson & Sorensen, Ballroom D)

Modeling of the loads on ships produced by an underwater explosion has been of intense interest in the naval shock community for many years.  This discussion session provides a forum for the exchange of ideas and experiences with the various noncontact UNDEX models in current use and development for shock simulations.  Recently, there has been a renewal of activity in explosion bubble dynamic models, and several new models have been proposed. However, a clear consensus has yet to emerge regarding the various strengths and weaknesses of the various models and, in particular, their relative utility in describing the actual pressure and acceleration fields in the vicinity of the ship structure.
 

1:00 - 3:00 PM:  Manufacturer's Panel - Moderator: Jon Wilson, The Dynamic Consultant LLC, (Ballroom AB)

How can we identify and define commercial practices or standards that can be adopted by system integrators and component suppliers to facilitate the utilization of COTS for military systems, thus providing the availability and survivability of state of the art electronics and systems for scheduled technology refresh cycles.  What steps need to be taken to provide the environment to make this possible?  The challenges facing both the Navy and commercial companies regarding COTS technology are well known.  Basically we have similar goals. ..to be able to provide state of the art electronics and equipment to ensure our military has leading edge capabilities.  In light of recent events, this has become even more critical.  We would like to explore some options and approaches for achieving these goals.  The presenters will give some historical perspective and concepts for meeting these challenges.  We would then like to open up the forum for constructive suggestions from you.  What are your experiences?  What do you think of the options presented?  Do you have other suggestions?  As a group, what can we do to improve the situation?  Panel members are Kevin E. Castanien, Engineering Manager, SPAWAR Consolidated Production Facility, SAIC, Information Technologies Integration Group, Jennifer Marr, Structural Engineer, NSWCCD/UERD, Ray Crandall, Hardware Technical Director for the LPD17 program, Contractor Furnished Equipment (CFE) designs., Raytheon Company, Robert L.

Shock & Vibration Standards (Co-Sponsored by the Acoustical Society of America) - Chair: Richard Taddeo, NAVSEA 05T (Ballroom AB)

2:40 - 4:40 PM: Shock & Vibration Standards Panel (Co-Sponsored by the Acoustical Society of America) - Moderator: Richard Taddeo, NAVSEA 05T (Ballroom AB)

The ASA Standards Secretariat is administratively responsible for ANSI S2 on Mechanical Vibration and Shock and for International Standards Organization (ISO) Committee TC108 and many of its sub committees. Several of the S2 and TC108 standards already published, as well as those in various stages of preparation by the Working Groups (WGs) are of significant value to the SAVIAC community. Panelists will present overviews of activities and published standards of S2 and TC108 in areas of special interest to the SAVIAC audience. These include but are not limited to Ship Vibration, Machinery Vibration, Transducers and Measurement, Signal Analysis, Modal Testing and more. Panelists and specific topic areas as well as issues to be covered will be published in the Final Program.

5:00 - 6:00 PM: Data Storage Standard Discussion Group (Co-Sponsored by the Acoustical Society of America & The International Institute of Acoustics and Vibration) - Leader: Dan Worth, NASA/Goddard Space Flight Center (Ballroom AB)

The price of storage media continues the decrease while the density of storage continues to increase making it so much easier to record large amounts of time-history data. Even though each manufacturer of acquisition and analysis systems has a proprietary binary format for time-history data, they usually provide a means of importing or data in text-based formats. Conversion to text format increases file sizes by an order of magnitude. Maybe it is time once again to revisit the establishment of a standard binary file format.
