The major objective of this paper is to describe a computer aided methodology for structural integration and analysis. Using the example of recent work in the installation of modular gun and vertical launch missile systems in warships, the reader is guided through a typical case of computer aided structural design and shock analysis, how the models are defined and tested, how the models are modified in order to be compatible with computer capacity, how structural elements are selected to simplify computations, and finally how the results of these operations are used to define the final product before construction and installation. With the maturation of the computer aided process as applied to the whole ship product, more attention must be focused on improving the individual elements of computer aided design (CAD), computer aided engineering (CAe) and computer aided manufacturing (CAM) and the integration of these processes and their products through computer integrated manufacturing (CIM). The application of the CAe techniques described herein to large maritime systems such as combatant, auxiliary and support, and commercial ships and to other large structures such as semisubmersible and fixed platforms is powerful and highly in demand. There is now a means to optimize large structural systems in terms of their discrete subsystems and components and harmonize the entire design while providing the proper design integrity at each successive level of detail.

作者： HOPe, JP STORTZ, Ve Jan Paul Hope a native of Northern Virginia received his bachelor of science degree in mechanical engineering from the University of Virginia in 1969. Upon graduation he began his career in the Department of the Navy with the Naval Ship Systems Command in the acquisition of patrol craft mine sweepers and submarine rescue ships. In January 1971 he transferred to the ship arrangements branch of the Naval Ship Engineering Center. He was selected for the long-term training program at George Washington University in 1974 and completed the program in February 1976 with the degree of master of engineering administration. While at the Naval Ship Engineering Center Mr. Hope was general arrangement task leader on the AO-177 CG-47 CSGN CSGN (VSTOL) CGN-9 (Aegis) and CGN-42 and he also assisted in the landmark Naval Sea Systems Command civilian professional community study. In 1978 he was selected as acting head of the damage control section and subsequently was selected as acting head of the surface ship hydrodynamic section. In February 1980 he was promoted to head of the surface combatant arrangements design section. Mr. Hope was selected for the first class of the NA VSEA commander's development program. While on the program he served in the DDGX combat systems engineering division and the DDGX project office of NA VSEA was the assistant director for ship design in the office of the Assistant Secretary of the Navy for shipbuilding and logistics and was the director of weight engineering and the director of systems engineering for the DDG-51 project in NA VSEA. Upon completion of the program Mr. Hope was assigned as the deputy director of the boiler engineering division to create a new division as a major fleet support initiative by NA VSEA. In June 1985 he joined the staff of the Assistant Secretary of the Navy for shipbuilding and logistics. Mr. Hope was presented the Department of the Navy meritorious civilian service medal in June 1983 for his service with the Office of the Assistant Secretary of the

This paper discusses the need and processes for designing warships to meet cost constraints and for managing warship acquisition programs during the design phase to assure effective adherence to production cost constraints by the design team. The resource control methodology used during the contract design of the Arleigh Burke class destroyer, DDG-51, is examined as a potential model for controlling the cost while maintaining the combat effectiveness of warships. The paper begins with a summary of the basic issue — the relationship among unit cost, unit capability, force level numbers, and force capability — showing recent trends in destroyer costs and force levels. This introduction also includes a discussion of the cost constraint for the DDG-51 in relation to historical trends and ship construction funding allocation. The resource control methodology used to reduce and control costs of the DDG-51 is discussed with a summary of the approach, key concepts and tools, chronology of key events, examples, and results achieved. A number of observations on this methodology are then made which are followed by comments on life cycle costs. The paper concludes with remarks on the future application of the resource control methodology and areas for further work to improve future resource control efforts.

A ship design methodology is presented for developing hull forms that attain improved performance in both seakeeping and resistance. Contrary to traditional practice, the methodology starts with developing a seakeeping-optimized hull form without making concessions to other performance considerations, such as resistance. The seakeeping-optimized hull is then modified to improve other performance characteristics without degrading the seakeeping. Presented is a point-design example produced by this methodology. Merits of the methodology and the point design are assessed on the basis of theoretical calculations and model experiments. This methodology is an integral part of the Hull Form Design System (HFDS) being developed for computer-supported naval ship design. The modularized character of HFDS and its application to hull form development are discussed.

作者： JOHNSON, RA CARACOSTAS, NP COMSTOCK, eN Mr. Robert A. Johnson is currently a Naval Architect in the Hull Group (SEA 32) Ship Design and Integration Directorate Naval Sea Systems Command. He received his Associate in Engineering degree in Drafting and Design Technology in 1959 his B.S. degree in Aerospace Engineering in 1965 and his M.S. degree in Engineering Mechanics in 1970 all from Pennsylvania State University. In 1973 he was selected for the Navy's Long-Term Training Program at the University of Michigan from which he received his M.S.E. degree in Naval Architecture in 1974. Mr. Johnson began his professional career at the Ordnance Research Laboratory Pennsylvania State University in 1959 where he was involved in the design of hydroelastic submarine models and conducted research in the area of flow-induced structural vibrations. Subsequently he joined HRB-Singer at State College Pennsylvania in 1967 as a Research Engineer and in 1969 joined the former Naval Ship Engineering Center (NAVSEC) where he was employed in the Submarine Structures Branch Surface Ship Structures Branch and the Performance and Stability Branch of the Hull Division.

The recent trend in Naval Forces has been a shrinking Fleet in both numbers and ship size. This dictates that our ships must have greater operational effectiveness if the Navy is to continue to carry out its mission in the future as it has done in the past. The seakeeping performance of a ship is a major determinant of its overall operational effectiveness. The methodology presented in this paper is a comprehensive approach to the evaluation of a ship's seakeeping performance. The scope of this methodology encompasses the assessment of ship mission scenarios and the relative importance of associated mission requirements as well as the probabilistic description of the uncertainties imposed by the variable ocean environment. The methodology is presented in a general sense so that the seakeeping performance of a ship's configuration can be evaluated as a function of mission scenario, mission area, sea state, ship heading, and speed. In order to utilize the full potential of the methodology, more refined scenario descriptions and more accurate environment specifications must be obtained. A simplified example is presented in which a comparison of the operational effectiveness of two small hull forms is made, using information now available to the designer. It is anticipated that the methodology presented can be used not only as a powerful tool in the decision-making process of practical ship design, but also as the basis for parametric studies of mission strategies.
