The 73rd Shock and Vibration Symposium
Conference Program
Monday, November 18Tutorials
Tuesday AM, November 197:00-7:30 AM: Author/ Chairs Meeting (Ballroom E)Opening Session (Ballroom ABCD)
Exhibitors' Luncheon - Exhibit AreaKey:T = TuesdayW = WednesdayH = Thursday(Room Locations are denoted in parentheses)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. Overview of CG47 Class Smartship Component Shock and Vibration Test Series - Chair: Robert Krezel, Consultant, Co-Chair: Barry Gartman, Anteon (Ballroom C)
Analytical Techniques - Chair: Dr. Robert Koch, NUWC (Ballroom D)
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.

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.

This session will discuss the topics and interrelations of code validation and precision testing, including the following questions and issues. What role does precision testing play in code validation? What are the roles of the modeler and the experimentalist in the design of precision tests? What is needed for a code to be validated? How much and what kinds of data are needed from a precision test? What needs to be done in precision tests to produce credible data? The importance of precision test characteristics, including geometry, boundary conditions, and material properties, and their importance to code validation will also be discussed.

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.
