Product Description:
This book introduces the subject of total design, and introduces the design and selection of various common mechanical engineering components and machine elements. These provide "building blocks", with which the engineer can practice his or her art.

The approach adopted for defining design follows that developed by the SEED (Sharing Experience in Engineering Design) programme where design is viewed as "the total activity necessary to provide a product or process to meet a market need." Within this framework the book concentrates on developing detailed mechanical design skills in the areas of bearings, shafts, gears, seals, belt and chain drives, clutches and brakes, springs and fasteners. Where standard components are available from manufacturers, the steps necessary for their specification and selection are developed.

The framework used within the text has been to provide descriptive and illustrative information to introduce principles and individual components and to expose the reader to the detailed methods and calculations necessary to specify and design or select a component. To provide the reader with sufficient information to develop the necessary skills to repeat calculations and selection processes, detailed examples and worked solutions are supplied throughout the text.

This book is principally a Year/Level 1 and 2 undergraduate text. Pre-requisite skills include some year one undergraduate mathematics, fluid mechanics and heat transfer, principles of materials, statics and dynamics. However, as the subjects are introduced in a descriptive and illustrative format and as full worked solutions are provided, it is possible for readers without this formal level of education to benefit from this book. The text is specifically aimed at automotive and mechanical engineering degree programmes and would be of value for modules in design, mechanical engineering design, design and manufacture, design studies, automotive power-train and transmission and tribology, as well as modules and project work incorporating a design element requiring knowledge about any of the content described.

The aims and objectives described are achieved by a short introductory chapters on total design, mechanical engineering and machine elements followed by ten chapters on machine elements covering: bearings, shafts, gears, seals, chain and belt drives, clutches and brakes, springs, fasteners and miscellaneous mechanisms. Chapters 14 and 15 introduce casings and enclosures and sensors and actuators, key features of most forms of mechanical technology. The subject of tolerancing from a component to a process level is introduced in Chapter 16. The last chapter serves to present an integrated design using the detailed design aspects covered within the book. The design methods where appropriate are developed to national and international standards (e.g. ANSI, ASME, AGMA, BSI, DIN, ISO).

The first edition of this text introduced a variety of machine elements as building blocks with which design of mechanical devices can be undertaken. The approach adopted of introducing and explaining the aspects of technology by means of text, photographs, diagrams and step-by-step procedures has been maintained. A number of important machine elements have been included in the new edition, fasteners, springs, sensors and actuators. They are included here. Chapters on total design, the scope of mechanical engineering and machine elements have been completely revised and updated. New chapters are included on casings and enclosures and miscellaneous mechanisms and the final chapter has been rewritten to provide an integrated approach. Multiple worked examples and completed solutions are included.

* New chapters on casings and enclosures, springs, and fasteners
* New information on important machine elements such as sensors and actuators
* Clear explanation of the total mechanical design process through the use of text, photographs, diagrams, step-by-step procedures and case studies

Summary: Good General Reference
Rating: 4
This is a reasonably "up to date" reference book for general mechanical design. The book has well organized solutions that include typical trial and error calculations that are close to real life design solutions where balance between what you need and what is available is often a necessary design compromise.

Highlights of Revisions for 2008

The 2008 ASHRAE Handbook—HVAC Systems and Equipment discusses various systems and the equipment (components or assemblies) that comprise them, and describes features and differences. This information helps system designers and operators in selecting and using equipment. An accompanying CD-ROM contains all the volume’s chapters in both I-P and SI units.

This edition includes two new chapters, described as follows:

Chapter 16, Ultraviolet Lamp Systems, includes a review of the fundamentals of UVC germicidal energy’s impact on microorganisms; how UVC lamps generate germicidal radiant energy; common approaches to the application of UVGI systems for upper-air room, in-duct, and surface cleansing; and a review of human safety and maintenance issues.
Chapter 17, Combustion Turbine Inlet Cooling (CTIC), provides a detailed discussion of how CTIC is used to help improve combustion turbine performance.

Some of the revisions and additions to the remainder of the volume are as follows:

Chapters 1 to 5 have each been revised to include new system and process flow diagrams, plus new discussion content on commissioning, building automation, maintenance management, sustainability/green design, security, and various systems (e.g., underfloor air distribution, chilled beams).
Chapter 7, Combined Heat and Power Systems, formerly entitled Cogeneration Systems and Engine and Turbine Drives, was reorganized, as well as updated for new technology.
Chapter 11, District Heating and Cooling, has new guidance on construction cost considerations, central plants, and distribution systems.
Chapter 12, Hydronic Heating and Cooling, has revised text and figures on all aspects of system design, including design procedure, water temperatures, heat transfer, distribution losses, constant- and variable-speed pumping, sizing control valves, and terminal units.
Chapter 18, Duct Construction, has new guidance for installation of flexible ducts.
Chapter 19, Room Air Distribution Equipment, was reorganized to coordinate with its companion chapter in HVAC Applications, with added content on equipment for stratified and partially stratified systems.
Chapter 24, Mechanical Dehumidifiers and Related Components, has new content on installation and service, indoor pool dehumidifiers, and application considerations for various equipment types.
Chapter 30, Automatic Fuel-Burning Systems, extensively reorganized and revised, contains updated information on new technology and code requirements.
Chapter 31, Boilers, has new material on condensing boilers, burner types, and operating and safety controls.
Chapter 32, Furnaces, has been thoroughly revised to reflect new technology and code requirements.
Chapter 34, Chimney, Vent, and Fireplace Systems, has been reorganized for clarity and has new content on designing fireplaces and their chimneys.
Chapter 36, Solar Energy Equipment, has been reorganized and has new content on photovoltaic systems and testing/rating.
Chapter 37, Compressors, has been reorganized and has updates on bearings and variable-speed drive technology.
Chapter 38, Condensers, contains revised content on air-cooled condensers, particularly on type descriptions, heat transfer, pressure drop, testing/rating, and installation and maintenance.
Chapter 40, Evaporative Air Cooling Equipment, has a rewritten section on indirect coolers.
Chapter 42, Liquid-Chilling Systems, has new discussion on both refrigerant selection and variable-flow chilled-water systems, as well as new and improved figures.
Chapter 44, Motors, Motor Controls, and Variable-Speed Drives, has updates for new technology and codes.
Chapter 48, Unitary Air Conditioners and Heat Pumps, has new content on multisplit units, variable-refrigerant-flow (VRF) equipment, certification, and sustainability.
This volume is published, both as a bound print volume and in electronic format on a CD-ROM, in two editions: one using inch-pound (I-P) units of measurement, the other using the International System of Units (SI).
