Opis

This book is designed to provide the new Computer Aided Design and Optimization tools and skills to generate real design synthesis of machine elements and systems on solid ground for better products and systems. This work provides the tool to directly obtain the synthesized real optimization tools to define the geometry and the particular selection of material. This is a new approach and a straightforward paradigm. It is divided into the following four parts: - Introduction and Design Considerations - Knowledge-based design: Introduction to the new Machine Element Design Synthesis - Introduction to computer aided design and optimization as tools used for Synthesis - Design of machine elements: Rigours traditional detailed design requirements These parts will include overview of chapters and enlightening design requirements.

SAYED M. METWALLI, is Professor Emeritus of Machine Design and past Chair of Mechanical Design and Production Department, Cairo University, Egypt. He received a BS (Mech. Eng.) with honor from Cairo University (1965) and MS and PhD (Mech. Eng.) from State University of New York at Buffalo, USA, (1970) and (1973) respectively. Metwalli has conducted research and taught at North Carolina State University, the University of Central Florida, USA, and Kuwait University, and holds a US patent. His research interests are in design optimization theory, developing algorithms, and CAD/CAM software, with particular emphasis on optimum synthesis of mechanical components and systems including dynamics and controls for multitude of applications. He has conducted sponsored research with DOD/NRL, UNESCO, IBM-UK, NSF, EPA, USAID, and CU and has published more than 150 papers in journals and peer reviewed international conferences. His work with various manufacturers successfully implemented CAD and design optimization in their product design and development. He is an ASME Life Fellow, registered mechanical design consultant, and has been a registered PE in Florida.
