THE MANAGEMENT OF SURFACE SHIP MAINTENANCE

NAVAL ENGINEERS JOURNAL 1980年第6期92卷 71-83页

作者： WOODRUFF, RB USN THE AUTHORgraduated from the U.S. Naval Academy with distinction in 1964. He served initially in theUSS Davis (DD-937)as Main Propulsion Assistant attended the Naval Destroyer School. and then was a member of the Pre-Commissioning Crew and Engineer Officer in theUSS Julius A. Furer (DEG-6).Selected as an Engineering Duty Officer (ED) in 1968. he had a tour in the Maintenance Department Staff of Commander Cruiser-Destroyer Force U.S. Atlantic Fleet at Newport. R.I. after which he attended Massachusetts Institute of Technology for graduate studies which culminated in his receiving his M.S. degree in Mechanical Engineering and his degree of Ocean Engineer in 1972. Following graduation he was assigned to the Boston Naval Shipyard followed by two years in theUSS Puget Sound (AD-38) asRepair Officer after which he was ordered to the Norfolk Naval Shipyard as the Production Engineering Officer. Currently he is on duty in the Naval Sea Systems Command (PMS 399) where he is the Trials Officer and Deputy Hull Technical Director for the OLIVER HAZARD PERRY (FFG 7) Class Acquisition Program. Cdr. Woodruff is a qualified Surface Warfare Officer. and among his military decorations holds the Naval Achievement Medal and the Vietnamese Meritorious Unit Citation Gallantry Cross. In addition to ASNE which he joined in 1967. he is a member of SNAME and the U.S. Naval Institute. and his two previous papers on Naval Shipyard Production presented at ASNE Day 1978 and 1979 were published in theNaval Engineers JournalVol. 90 No. 2 (April 1978) and Vol. 91. No. 2 (April 1979).

The purpose of the paper is to address the current dilemma facing the Surface Ship Navy as it approaches the twenty-first century. The basic underlying thesis is that the Maintenance Community has lost sight of the goal it must have: to support the Commanding Officer of a ship to get his ship from point A to point B with its weapons system ready. To do this, three basic things must occur: 1) the ship must be capable of getting underway and steaming (i.e., turn the screw); 2) the ship must have its weapons systems working and “up” in all respects (i.e., fight the ship); and 3) the Crew must be prepared (i.e., have sufficient training). It Is submitted that we have lost sight of this fact. There remains an inordinate amount of concern over appearance (external and internal), habitability, plaques, inspections, and various human factors programs, and funds may be spent in there areas when the main machinery plant and missile systems are “down.” A recent example is the effort to remove every speck of wood from all Navy ships including picture frames. Training is addressed also as the third key element missing, particularly in the main machinery spaces. A brief examination is made of the ship cycle as it gas into the maintenance mode, i.e., delivery plus one to two years. A comparison is made with the basic Submarine Force approach to this problem and when the Surface Community may take a page out of the Submarine Force book. An addressed are: 1) Current Ship's Maintenance Project (CSMP); 2) Planned Maintenance System (PMS); 3) Pre-Overhaul Test and Inspection (POT&I); 4) Long lead time SHIPALT material, 5) Intermediate Maintenance Activity (IMA) role (Tenders and SIMAS); and 6) Shipyard role and facilities.

Naval Engineers Journal 1975年第6期87卷 79-96页

作者： FAIRBANKS, JOHN W. The author is a graduate of the Maine Maritime Academy Stanford University and the University of Santa Clara. His undergraduate degrees were in Marine and Mechanical Engineering and his Masters Degree Specialization was in Heat-Mass-Momentum Transfer within the Mechanical Engineering Department He has taught Gas Dynamics Thermodynamics and Direct Energy Conversion at Texas A&M and the University of Maryland and has sailed as a licensed Marine Engineer for two and a half years with the American Export Lines currently holding active First Assistant Steam Unlimited and Third Assistant Diesel Unlimited licenses. From 1954 to 1957 he was on active duty in the U.S. Navy serving in the USS Montrose (APA-212) as both Main Propulsion Assistant and Chief Engineer. While employed at Hiller Aircraft Company he was in the Advanced Research Group and worked on the Detached Coanda Effect for VTOL and ground effect machines as well as designing high-speed bearings and high-speed shaft test stands for the SC-142A an experimental tilt wing aircraft program. In 1963 he went to Philco-Ford to design a Brayton Cycle Power System for a solar probe spacecraft and also worked on the Thermal and Power System Design of the IDCSP (DOD's Communication Satellite). At NASA's Goddard Space Center for six years his responsibilities included design fabrication integration test launch and flight operation of solar arrays on two spacecraft and also as Power Systems Engineer for the Orbiting Astronomical Observatory the largest unmanned spacecraft flown. In 1971 he joined NAVSEC where he is currently the Program Engineer on the FT9 Gas Turbine Development Program and Coordinator of the Navy's Materials Programs for advanced gas turbines. Having organized the first two Navy Gas Turbine Materials Conferences he is presently organizing U.S. participation in a joint U.S. Navy Royal Navy Gas Turbine Materials Conference to be held in ‘the United Kingdom in September 1976. Mr. Fairbanks has authored or coauthored 21 technical papers and i

The current Navy philosophy for marine gas turbine engine development is to marinize an existing aircraft turbo jet engine. The FT9 Marine Gas Turbine Engine is a 33,000 horsepower version of the Pratt and Whitney JT9D engine, which powers the 747 aircraft. Marinization of the JT9D basically involves removal of the fan section, addition of a power turbine, structural modification to several components, and material changes to provide corrosion‐resistance in the marine environment. Characteristics and ratings of the individual engine components are discussed as well as the assembled engine. The FT9 design incorporates the modular replacement concept. Modular replacement permits replacement of short‐life components such as the hot‐section without removing the engine from its mounts. The FT9 specification requires development of a condition monitoring system as an integral part of the engine development. Thus, provisions for sensor installations are incorporated in the design. Accelerometers are installed on the internal engine bearing housings to provide improved vibration signals. These accelerometers are mounted on rods such that they are removable without engine disassembly. Extensive borescope provisions are included to provide capability to inspect all hot‐section components without disassembling the engine. The engine life‐limiting component is the hot‐section because of the susceptibility of the blade and vane materials to sulphidation/oxidation at the temperatures encountered with the advanced engines. Sophisticated Made and vane cooling is used to allow high turbine inlet temperatures while keeping blade metal temperatures in a region where sulphidation/oxidation is only moderately active. Coatings are added to blades and vanes to extend engine life. Three FT9 engines will be delivered to the Navy. The target date for provisional Service Approval of FT9 is mid‐1978. FT9 will provide the U.S. Navy with the most advanced marine gas turbine with the highest powe

One of the problems encountered during the design of the ASR‐21 Catamaran is the determination of the effectiveness of the cross‐structure deck plating. In this paper, this problem is examined using the Finite Element Method. The behavior of a multicell box girder representing a catamaran cross‐structure is studied. Because of the relatively low length‐to‐breadth ratio of a typical catamaran cross‐structure, the deck plating effectiveness is found to be rather small. Parametric studies are performed, and curves of the effectiveness as a function of the relevant geometric and loading parameters are presented. These curves may be helpful in the early stages of new designs. © 1973 by the American Society of Naval Engineers

Practical Bilevel Optimization 1

引用

丛书名： Nonconvex Optimization and Its Applications

1000年

作者： Jonathan F. Bard

ISBN: (数字)9781475728361

ISBN: (纸本)9780792354581;9781441948076

The use of optimization techniques has become integral to the design and analysis of most industrial and socio-economic systems. Great strides have been made recently in the solution of large-scale problems arising in such areas as production planning, airline scheduling, government regulation, and engineering design, to name a few. Analysts have found, however, that standard mathematical programming models are often inadequate in these situations because more than a single objective function and a single decision maker are involved. Multiple objective programming deals with the extension of optimization techniques to account for several objective functions, while game theory deals with the inter-personal dynamics surrounding conflict. Bilevel programming, the focus of this book, is in a narrow sense the combination of the two. It addresses the problern in which two decision makers, each with their individual objectives, act and react in a noncooperative, sequential manner. The actions of one affect the choices and payoffs available to the other but neither player can completely dominate the other in the traditional sense.

Dynamic Walking: Toward Agile and Efficient Bipedal Robots

引用

Control, Robotics, and Autonomous Systems 1000年第1期4卷 535-572页

作者： Jenna Reher Aaron D. Ames 1Department of Mechanical and Civil Engineering California Institute of Technology Pasadena California 91125 USA email: jreher@caltech.eduames@caltech.edu 2Control and Dynamical Systems Graduate Program California Institute of Technology Pasadena California 91125 USA

Dynamic walking on bipedal robots has evolved from an idea in science fiction to a practical reality. This is due to continued progress in three key areas: a mathematical understanding of locomotion, the computational ability to encode this mathematics through optimization, and the hardware capable of realizing this understanding in practice. In this context, this review outlines the end-to-end process of methods that have proven effective in the literature for achieving dynamic walking on bipedal robots. We begin by introducing mathematical models of locomotion, from reduced-order models that capture essential walking behaviors to hybrid dynamical systems that encode the full-order continuous dynamics along with discrete foot-strike dynamics. These models form the basis for gait generation via (nonlinear) optimization problems. Finally, models and their generated gaits merge in the context of real-time control, wherein walking behaviors are translated to hardware. The concepts presented are illustrated throughout in simulation, and experimental instantiations on multiple walking platforms are highlighted to demonstrate the ability to realize dynamic walking on bipedal robots that is both agile and efficient.

The Significance of Certain Parameters in Buoyancy System Performance

引用

Naval Engineers Journal 1971年第4期83卷 75-81页

作者： HANSEN, O. RICHARD UHLER, DALE G. O. Richard Hansen obtained a BSCE from Colorado State University in 1950 and has participated in continuing educational courses at the University of Washington Wayne State University and the University of Michigan. He was employed at Puget Sound Naval Shipyard for five years as a Mechanical Engineer and Project leader in industrial gases and cryogenic O2. Producers for Shipboard Applications followed by seven years at Chrysler Corporation initially as a project engineer in the FBM program subsequently assigned to Mechanical Laboratory achieving Managing Engineer status of a department therein which contained the facilities group instrumentation group and an experimental machine shop. This was followed by employment at Westinghouse Astronuclear Laboratories as a senior engineer conducting studies in two phase liquid hydrogen flow in simulated NERVA cores. Following this he served two years of employment with the Lockheed Georgia Company conducting material studies in combined nuclear cryogenic environments at the NASA 60 megawatt test reactor located in Sandusky Ohio. Joined NAVSEC in 1966 as a mechanical engineer in the compressed air systems group and has been assigned to the Supervisor of Diving Salvage and Ocean Engineering conducting analysis and evaluation of compressed air and gas systems associated with diving and salvage operations. Dale G. Uhler received BSCE degree from Carnegie Institute of Technology in 1964. He spent two years as a construction engineer before entering graduate school at the University of Miami Florida where he received his MS degree in applied mechanics with a minor in Ocean Engineering in 1968. He is now employed as an Ocean Engineer in the office of the U. S. Navy Director of Diving Salvage and Ocean Engineering where he is the project manager for the Large Object Salvage System and related development programs and concurrently working toward his Ph. D. at Catholic University.

The advent of deep ocean technology has created a need of buoyancy at ever increasing depths. This paper concerns itself with two most widely used techniques for dewatering/deballasting, compressed air supplied by surface maintained compressors and high pressure gases contained in pressure vessels. The objective of the paper is to examine the effects on these two techniques of various parameters which, in the author's opinion, are often overlooked by design engineers. This results in a significant degradation of the system under actual operating conditions. The principal parameters involved are structural integrity, geometric properties, material properties and the variance with pressure of the real gas properties and sea water density. This paper is an attempt to appraise designers and users of the impact of the above considerations on proposed buoyancy systems. © 1971 American Society of Naval Engineers
