کتابی در خصوص انواع مکانیزمها و سیستمهای مکانیکی :

This is the third edition of Mechanisms & Mechanical Devices Sourcebook, a well illustrated reference book containing a wide range of information on both classical and modern mechanisms and mechanical devices. This edition retains a large core of the contents from both the first and second editions, (published in 1991 and 1996, respectively), that has been supplemented by new and revised articles reflecting present and future trends in mechanical engineering and machine design. The new articles in this edition address topics that are covered regularly in mechanical engineering and science magazines as well as being the subjects of technical papers presented at engineering conferences. Among these new articles is an overview of motion control systems, highlighting the influence of programmable computer and digital technology on those systems. Other articles discuss servomotors, actuators, solenoids, and feedback sensors—important electromechanical, and electronic components used in motion control systems. Also included are articles on gearheads, single-axis motion guides, and X-Y motion systems assembled from stock mechanical components. Other articles in this edition describe commercially available 2D and 3D CAD (computer- aided design) software and update previous articleson industrial robots and rapid prototyping (RP) systems. Another article reviews recent research in MEMS (microelectromechanical systems) and recent spinoffs of that technology. All of these subjects are continuing to influence the direction of mechanical engineering, and they are having a profound impact on engineering education and practice

Since the publication of the second edition, the term mechatronics has gained wider acceptance as a word that identifies an ongoing trend in mechanical engineering—the merging of mechanics, electronics, and computer science. Coined in Japan in the 1970s, mechatronics describes the synergistic blend of technologies that has led to the creation of many new functional and adaptable products that could not have been produced with a purely mechanical approach. While there is no formal definition of mechatronics, most mechanical engineers agree on its meaning. The concept of mechatronics has been illustrated as a Venn diagram showing four overlapping circles representing the fields of mechanics, electronics, computers, and controls. Over the years, this convergence has spawned the more specialized disciplines of electromechanics, computer-aided design, control electronics, and digital control systems, all considered to be within the purview of mechatronics. These specialties have, in turn, fostered the creation of the even more focused technologies of system analysis, transducers, simulation, and microcontrollers
