Gear shaving is one of the most efficient and economical ways to finish gears after gear hobbing or gear shaping. In tradition, the shaved gear can be crowning by shaving machine with the rocking mechanism. In this paper, we propose a mathematical model of a CNC shaving machine with two synchronous axes. The proposed mathematical model can be used to calculate the crowning tooth surface of the gear in parallel-shaving process.

While most of the theater ballistic missiles (TBM) in threat countries' inventories are of the shorter range sCUD varieties, mid- to long-range versions are currently in development in a number of third world countries. Threat potential exists in the following three battle spaces: endo-atmosphere (0-30 km), high endo-atmosphere (30-70 km) and exo-atmosphere (greater than 70 km). The inherent short range and low speed of endo-atmospheric threats match well with capabilities of sM-2 Block IVA, which equips the Navy with an area defense capability The exo-atmospheric TBMs are longer range and can threaten more targets which may be widely dispersed. Their higher velocities reduce response times dramatically Therefore, exo-atmospheric TBMs create the need for standard Missile-3 (sM-3), which provides the Navy with theater wide defense capability. Defining its area and theater wide systems as clearly endo-atmospheric and exo-atmospheric systems allows the Navy to use derivatives of the standard Missile Block IV to take full advantage of the conditions associated with each of these operating zones. Use of an existing missile and ship system baseline also allows use of the existing interface structure to minimize cost. To counter the endo-atmospheric TBMs, the sM-2 BLK TVA upgrades include an advanced imaging infrared (IIR) seeker, an improved fast-reaction auto pilot and a forward looking RE all in the same volume as the existing missile. The highly responsive sM-2 Block IVA missile, complemented with Aegis weapons systems modifications, provides capability against enemy aircraft and cruise missiles, as well as TBMs. standard Missile-3 (sM-3) replaces the sM-2 Block TV warhead, radar and guidance section with a boosted third stage and an advanced kinetic warhead (KW). Operation in the exo-atmospheric region permits a KW design with autonomous guidance control and divert thrusters for high maneuverability and has the capability of achieving very high interceptor velocities.

NAVAL ENGINEERs JOURNAL 1988年第1期100卷 45-52页

作者： EXELL, JR KILLINGER, A LCdr. John R. Excell: USN received a bachelor of architecture from the University of Michigan and a master of science degree in mechanical engineering from the U. S. Navy Postgraduate School. He was commissioned in 1973 serving first as damage control assistant aboard USSGuadalcanal(LPH-7) and later as commissioning main propulsion assistant on USSMerrill(DD-976). He became an engineering duty officer in 1979 and served at Norfolk Naval Shipyard as senior ship superintendent for six ships and later within the shipyard Design Department. In May 1984 LCdr. Exell was assigned to the DD-963 Class Special Projects Office as program manager for air system improvements including the bleed air and anti-ice systems. He recently completed the Defense Systems Management College Ft. Belvoir VA and returned to NavSea PMS 377 as deputy for strategic sealift programs. Arthur Killinger:graduated from the University of Maryland in 1968 with a bachelor of science degree in mechanical engineering. He joined MPR Associates Inc. working on submarine safety design reviews following the loss of USSScorpion(SSN 589). After two years in the U.S. Army Nuclear Reactor Program and a year as U.S. Army engineer maintenance advisor in the Republic of Vietnam he returned to MPR Associates Inc. in 1972. Since then he has worked on nuclear power plant projects for several electric utilities as well as submarine and surface ship overhaul and maintenance improvement programs for the U.S. Navy. Mr. Killinger is a member of the American Society of Naval Engineers and the American Society of Mechanical Engineers.

This paper describes the steps taken to simplify the gas turbine intake anti-ice systems on DD-963 and DDG-993 class ships. The anti-ice system was designed and built as fully-automatic protection against intake duct icing on main propulsion turbines and electric generator turbines. Operating experience with the system indicated that it was nonfunctional more than 60% of the time. The system's poor availability was caused by its complexity, lack of use, lack of spare parts, poor training and documentation, and design and material problems. A Navy Independent design Review Team (IDRT) reexamined the technical bases for installing an automatic anti-ice system and demonstrated that automatic control was not necessary for gas turbine intake duct anti-icing. A series of design review calculations and shipboard tests confirmed that anti-icing protection could be provided by manual control of installed butterfly valves feeding hot air to each turbine intake. The time from the IDRT design simplification recommendations to the first modification of the anti-ice system was less than one year. To date, half of the 30 of the 35 ships in the two classes have been modified. This system simplification will result in life cycle maintenance cost savings in excess of 13 million dollars. Future CG-47 class and DDG-51 class ships will include this simplified approach to anti-ice system design for gas turbine intakes.

A prototype concurrent engineering tool has been developed for the preliminary design of composite topside structures for modern navy warships. This tool, named GELs for the Concurrent Engineering of Layered structures, provides designers with an immediate assessment of the impacts of their decisions on several disciplines which are important to the performance of a modern naval topside structure, including electromagnetic interference effects (EMI), radar cross section (RCs), structural integrity, cost, and weight. Preliminary analysis modules in each of these disciplines are integrated to operate from a common set of design variables and a common materials database. Performance in each discipline and an overall fitness function for the concept are then evaluated. A graphical user interface (GUI) is used to define requirements and to display the results from the technical analysis modules. Optimization techniques, including feasible sequential quadratic programming (FsQP) and exhaustive search are used to modify the design variables to satisfy all requirements simultaneously. The development of this tool, the technical modules, and their integration are discussed noting the decisions and compromises required to develop and integrate the modules into a prototype conceptual design tool.

Electromagnetic interference (EMI) is one of the major contributors to mission degradation in our fleet today due to the increase in population and sensitivity of both topside and below deck electronic systems. sensitive combat systems designed to counter intelligent and deceptive targets can be confused by the complex intra-ship EM environment. This can cause identification failure or losing "track" of a hostile or incoming missile or even engaging "friendly targets." Topside design and integration efforts have been used to reduce EMI, but this is not the total solution to the problem. A program of total ship and system EMI assessment and control must be implemented. This program must exploit electromagnetic compatibility (EMC) optimization in electronic circuit design and take advantage of and (in some cases) direct topside shapes and structures to control the propagation of desired and undesired EM energy. Positive and active control of EM design characteristics are absolutely required before optimum combat system effectiveness can be realized. This paper will describe the current topside design process, EMC improvements being made, and how the process is being integrated into, and is dependent upon, the ship design process. It will give examples of some of the major mission degrading EMI problems in the fleet today and how past problems were solved with existing EM analysis programs. It will also discuss the control of EM energy in new design through the use of techniques being developed such as ray tracing and ray casting. The paper projects where the challenges lie for future topside and EM engineering designers and describes how the equipment technology transfer process must be better integrated to meet the challenge of effective EMI control.

''Turn-Key'' is an innovative approach for the design, acquisition, integration, and installation of Radio Communications systems for new construction ships. It has been developed bv the space and Naval Warfare systems Command (spaWar) to cope with the growing problem of ships being delivered to the fleet with outdated or obsolete communications technology. The Turn-Kev approach provides botb performance and affordabilitv benerits. Under the traditional ship design process, the baseline configuration of the communications suite is effectivelv frozen 5-7 years before deliverv of the ship. In the current fixed price shipbuilding environment, the costs of engineering change proposals (ECPs) to implement communications suite design changes have become prohibitive. The design inflexibilitv created by these schedule and cost constraints affects the Navv's abilitv to implement communications technology advancements in new construction ships. At the point of delivery, most new construction ships alreadv have an inherent ''bow-wave of required communications subsystem/equipment upgrades which must be accomplished under the Fleet Modernization program. Under the turn-kev approach, the Navv assumes full responsibility for design, acquisition, land-based system integration, and (in some cases) shipboard installation and test of the communications suite. The shipbuilder provides necessarv electrical power, ventilation, and cooling services, based on established allocations. This approach greatly reduces the Navy's GFI requirements and ECP costs to the shipbuilder and therebv gains the design flexibilitv necessarv for incorporation of up-to-date communications technology prior to ship delivery. since the shipbuilding ECP cost penalties associated with implementing communications technology upgrades are reduced, the turn-key approach enables performance improvements while providing affordabilitv benefits. The turn-key approach already has been used successfully for installation of

NAVAL ENGINEERs JOURNAL 1984年第3期96卷 25-38页

作者： sIMs, PJ EDWARDs, JR DICKEY, RL sHULL, Hs Philip J. Sims:graduated from Webb Institute in 1971 and went to work for the Advance Design Branch of the Naval Ship Engineering Center. He was part of the FFG-7 design team in 1972. The 1973–75 years were spent developing automated early-stage aircraft carrier design procedures and performing carrier design trade-off work in support of the CVV design. He returned to school in 1976 for a masters at M.I. T. The 1977–80 period was spent updating the Navy's destroyer-cruiser early-stage design procedures and performing studies for the CGN-42 reserve FFX and DDX (later DDG 51) projects. Also during this period he was team leader on concept formulation (CONFORM) studies of new ships such as a heavy combatant and a low detectability ship. From 1981 to early 1983 Mr. Sims was Design Integration Manager for the BB-62 and Ship Design Manager for the BB-61 and CA-134. He is presently principal naval architect for the FFX study and also works on the NA TO frigate effort. James F. Edwards Sr:.is the Technical Director Ship Analytics Inc. Washington D.C. Operations and was the Ship Design Manager for the battleship USSNew Jerseyprior to his departure from NAVSEA in August 1983. He joined the U.S. Navy Reserves in 1954 and served on active duty from 1957 to 1960. From 1961 to 1963 he worked for McLaughlin Research Corporation as a section head in the drafting department. From 1963 to 1966 he worked for the Vitro Corporation of America in the Terrier (surface missile systems) Department. In 1966 he participated in the contract design of the first shipboard integrated digital ASW Command and Control system while working for the Stanwick Corporation. In 1967 Mr. Edwards accepted a position at NAVSHIPS in the Combat System Integration Division. In 1974 he transferred to what is currently NAVSEA's Hull Design Division. In 1980 Mr. Edwards was designated as the Battleship and Heavy Cruiser General Arrangements Task Leader and subsequently served as the Hull Task Group Manager the Ship Configuration Control Manager and fina

In reactivating the battleship New Jersey , the Navy faced three major problems. The baseline data on the ship was not readily available or reliable, a new generation cruise missile armament was proposed, and the ship delivery schedule was very tight. After doing a feasibility study, system design engineers were taken onboard the mothballed ship to resolve the design problems. Being on the ship allowed an intensive effort and immediate reference to the actual ship configuration. The tools used to control this effort were a ship check plan, a ship check form and the master arrangement drawing. simultaneously with the design effort, a repair scoping effort was conducted. The design evolution and solutions to the major problems are described. The results of the New Jersey effort are shown with sample documentation, the ship characteristics and the downstream design effort. The Iowa was the next ship to be modernized. The top level requirements were the same as New Jersey's but new problems were encountered. More options were investigated which diverted attention from the basic effort. A fundamental difference was the Iowa had not had a 1968 reactivation as the New Jersey had, so items that were repair and reactivation on the New Jersey in 1968 had to be part of the Iowa modernization. A major influence on the Iowa design process was that a complete set of specifications for a private yard bid had to be developed. The next effort was to install the same New Jersey modernization payload on a Des Moines class heavy cruiser. Heavy cruisers are large ships but significantly smaller than battleships and much closer to their naval architectural limits of weight and center of gravity. They have much less topside area than the battleships, and the new payload was very topside space consuming. The cruisers are also much more restricted in internal volume. Two feasibility studies were conducted. One resolved volume problems but approached the weight and center of gravity limits.

作者： KINNEY, ET CONsTANT, A Edward T. Kinney a native of Grand Rapids Michigan earned his Bachelor of Science degree with honors in Civil Engineering from Michigan State University in 1952. He began his career with the Bureau of Ships as a Naval Architect in the Hull Design Training Program in September 1952. Kinney has served as a Project Coordinator in the Machinery Systems Division and is currently Head of the Environmental Pollution Control Branch at the Naval Ship Engineering Center. He is a member of several committees including the Department of Defense Environmental Pollution Control Committee and the Interagency Committee on Vessel Pollution Standards. Alexander Constant graduated from Pennsylvania Military College in June 1960 with a B.S. in Civil Engineering. After two years with the U.S. Forest Services working as a Civil Sanitary Engineer designing recreational facilities Constant joined the Vermont Water Resources Department as a Project Engineer. For the past five years he has been associated with the Naval Ship Engineering Center Piping System Branch responsible for design and development of systems and equipment to abate and control shipboard generated waste. He is presently Acting Head of the Sewage and Waste Water Section of the Environmental Pollution Control Branch NavSec.

The Navy, as well as other Federal Agencies and the private sector, has a clear mandate to stop polluting the environment, Various sources of environmental pollution caused by the operation of naval ships are discussed and characterized by the following general categories: sewage; Oil; Industrial; Combustion Products; and Other Mission Related Wastes. Existing procedures for controlling these pollutants and advanced concepts for more complete control are discussed. Currently a very small percentage of ships are equipped to control environmental pollution. Complete control of ship wastes will be very costly and technically challenging. The first steps to effect control have been taken but greater strides are required.
