DDG-51 CLASS COMPUTER-AIDED-design

引用

NAVAL ENGINEERS JOURNAL 1994年第4期106卷 165-173页

作者： OUILLETTE, JJ THE AUTHOR is the DDG-51 class computer-aided design project manager in the Navy's Aegis program office. Ms. Ouillette is 1986 graduate of the University of Maine with a B.S. in mechanical engineering. Prior to her current position Ms. Ouillette was employed by the Supervisor of Shipbuilding Conversion and Repair Bath Me. where she was involved with engineering systems management for the DDG-51 class program.

Computer-Aided design and Computer-Aided Manufacturing technology is being implemented in the U.S. Navy's Arleigh Burke (DDG-51) Class Aegis Destroyer program. Under the Navy's direction, the DDG-51 class construction yards are aggressively pursuing the transition to CAD-based design, construction and life cycle support. Through the CAD initiative, acquisition costs can be reduced without reduction of ships' capability. Building a three dimensional (3D) computer generated model of the ship prior to construction will facilitate the identification and resolution of interference and interface problems that would otherwise remain undetected until actual ship construction. The 3D database contains geometry and design data to support system design and concurrent engineering and is exchanged electronically between the construction yards. Detailed design drawings, fabrication sketches, and numerical control (NC) data are extracted directly from the database to support construction. At the completion of ship construction, as-built models will be provided to the planning yard for life cycle support.

In 1988 he was detailed to the Defense Advanced Research Projects Agency (DARPA) where he became the program manager for the advanced submarine technology program's hydrodynamic hydroac

A major contributor to the expense and length of time to design, build, and test new systems has been the need to build and test hardware prototypes to determine their effectiveness in meeting operational requirements. Recent and dramatic advances in computer simulation technologies hold forth the promise of revolutionizing design and acquisition strategies by providing the means to validate end users' requirements prior to hardware construction. By designing and operationally testing virtual prototypes in a virtual environment, these technologies will soon offer naval architects the ability to build and launch ships in computer-based cyberspace in lieu of the shipbuilder's ways. The authors of this paper provide the background for these developments, explore the significance and ramifications of these technologies to the current process of ship and system design, outline challenges lying ahead, and present their vision and recommendations for future development.

Live Fire Test and Evaluation (LFT&E) is a relatively recent addition to the requirements for ship acquisition programs. Ship LFT&E requires a combination of testing and analysis in order to evaluate the vulnerability of a new acquisition ship class to the threat weapons it is likely to encounter in combat. LFT&E supports the ship acquisition process by identifying vulnerability weaknesses early in a development program and enabling timely, well informed decisions regarding ship vulnerability reduction features. This paper discusses the various aspects of ship LFT&E and how they relate to make a positive impact on a ship acquisition program in a timely fashion. It describes a four-element approach to ship LFT&E consisting of (1) component, system, and full-scale ship tests, (2) surrogate tests, (3) damage scenario-based engineering analyses, and (4) a Total Ship Survivability Trial demonstrating the ability of the full-up ship to combat damage and ''fight hurt.''

In early 1990, the U.S. Coast Guard embarked on a major program to replace its fifty‐year‐old seagoing buoy tender fleet by requesting proposals for designs that would meet the Circular of Requirements (COR) for the replacement cutter. Subsequently, three shipyards were awarded contracts to develop contract designs and specifications for the vessel. On 28 January 1993, Marinette Marine Corporation (MMC) was awarded a contract for construction of the Juniper, the lead ship of the new class of Coast Guard seagoing buoy tenders. From even a cursory examination of the COR, while buoy tending remains the Juniper's primary mission, she will serve as a multi‐mission vessel capable of recovering spilled oil, performing icebreaking, servicing fixed stations and other vessels with fuel, water and cargo, as well as conducting search and rescue and law enforcement operations. This paper lists the requirements and describes the resulting successful design that meets these requirements and has been designated the Juniper class by the U.S. Coast Guard. © 1994 by the American Society of Naval Engineers

WHY ENGINEERS DONT UNDERSTAND LOGISTICS

引用

NAVAL ENGINEERS JOURNAL 1992年第5期104卷 57-63页

作者： LIGHT, SP The Authoris currently the director Logistics and Material Division Security Assistance Program Management Office (PMS 380) in the Surface Combatants Directorate (SEA 91) Naval Sea Systems Command. He received his BS degree in mechanical engineering from West Virginia Institute of Technology his MS degree in systems management from the University of Southern California and he is a graduate of the Defense Systems Management College. He is also certified as a member of the NavSea's Civilian Material Professional Career Program. Among his previous employments Mr. Light has held engineering and logistics management positions with the U.S. Coast Guard Headquarters in the Naval Engineering Division the Naval Ship Systems Command Engineering Interface Management Office and the Naval Ship Engineering Center where he served as manager of integrated logistics support for the FFG-7 Ship Design Project Office. He also served as the ILS manager for the CG-47 and DDG-51 ship programs during the design phases of these programs. Mr. Light was also the director of the Acquisition and Logistics Office for Surface Combatants (SEA 91) between 1984 to 1991. Mr. Light has twenty-eight years of experience in surface ship design acquisition maintenance and logistics.

The author describes his observations during twenty-eight years of naval ship design, acquisition and logistics support experience that engineers do not understand logistics or even consider logistics as part of their engineering responsibilities. This paper will explore the reasons why. The paper will also provide reasons why the engineer should understand logistics and why it should become a part of the engineer's responsibilities and lexicon. The paper presents the position that an engineer armed with a knowledge of logistics can do the best job in producing a good supportability design. Recommendations are provided to the naval engineering and logistics communities to increase the logistics knowledge of engineers. Also, the author advocates the development of design techniques to be used by the engineer to produce good supportability designs. The increased role of the engineer in applying supportability design techniques will be required in the future if we are to do more with the planned reductions in the acquisition workforce.

The SA'AR-5 Corvette program is the first major warship construction to be entirely accomplished using a 3-dimensional, interference checked computer based design. This paper discusses the organization and approach used to create the design models which form the basis for interference checking as well as the source of extracted production data. The design or product model is the nucleus of the computer data base that defines the configuration of the entire ship. The data base includes geometry, weight, and material, as well as production control data. The ability of the computer to link such diverse information is the key to maintaining configuration control during the course of the design and construction. The ease with which formatted manufacturing data (both N.C. fabrication and installation) can be extracted enables the preparation of detailed packages containing the desired geometry as well as the associated material and sequencing data, thus assuring the producibility of the design. The SA'AR-5 design is CAD/CAM's state of the art in U.S. shipbuilding.

He received M.S. degrees in civil/structural engineering from Carollo Wilhelmina University in West Germany. He is a registered professional engineer. Gregory D. Woodsis the Naval Sea Systems Command's lightweight metallic structures program manager. Until recently a naval architect in the Structural Integrity Application Division he currently works in the Amphibious Auxiliary and Support Ship Branch. He received a B.S. degree in mechanical engineering from Tennessee State University with additional graduate level course work at the NavSea Institute. Anthony J. Furiois the program manager for lightweight metallic structures in the Ship Structure Division of the David Taylor Research Center. He has over 19 years of experience in ship structure research and light weight metallic development for U.S. Navy fleet applications. He received a B.S. in civil engineering from Long Island University and a M.S. in ocean engineering from Stevens Institute of Technology.

Since the early 1980s, the U.S. Navy, in conjunction with industry, has continued to develop and test innovative lightweight structural concepts with the purpose of seeking alternative replacements for conventional plate beam metallic structures. One commercially available concept currently under investigation is lightweight metallic corrugated core sandwich panels. This paper presents both elastic and plastic design methods for lightweight metallic corrugated core sandwich panels subjected to air blast loading. The equations presented in this paper, while not a complete solution to the complicated dynamic, elastic plastic phenomena of blast wave-rigid body interaction, are offered as a set of relatively simple analytical expressions that can be used in preliminary design. Because of the closed form nature of the equations the designer has the capability to quickly identify the most important parameters effecting the response of lightweight metallic corrugated core sandwich panels to air blast loads.
