Part I of this book is an introduction that deals mostly with theory, with nomenclature, with notation, and with methods of analysis. Serving as an introduction, Chapter 1 also tells what a mechanism is, what a mechanism can do, how they can be classified, and some of their limitations. Chapters 2, 3, and 4 are concerned totally with analysis, specifically with kinematic analysis, since they cover position, velocity, and acceleration analyses, respectively. Part II of the book goes on to show engineering applications involving the selection, the specification, the design, and the sizing of mechanisms to accomplish specific motion objectives. This part includes chapters on cam systems, gears, gear trains, synthesis of linkages, spatial mechanisms, and robotics. Part III then adds the dynamics of machines. In a sense this is concerned with the consequences of the proposed mechanism design specifications. In other words, having designed a machine by selecting, specifying, and sizing the various components, what happens during the operation of the machine? What forces are produced? Are there any unexpected operating results? Will the proposed design be satisfactory in all respects? In addition, new dynamic devices are presented whose functions can not be explained or understood without dynamic analysis. The third edition includes complete new chapters on the analysis and design of flywheels, governors, and gyroscopes. |
