This is the fifth edition of a one-of-a-kind engineering reference book covering the past, present, and future of mechanisms and mechanical devices. It includes clear illustrations and straightforward descriptions of specific subjects rather than the theory and mathematics found in most engineering textbooks. You will find that this book contains hundreds of detailed line drawings that will hold your interest regardless of your background in mechanical engineering. The text accompanying the illustrations is intended to help you to understand the basic concepts of subjects that may or may not be familiar to you. You will find drawings and illustrations that are simply interesting and informative and perhaps others that could spur your creativity and prompt you to recycle them into your new designs or redesigns. They may offer solutions you had not previously considered because they were not visible inside contemporary products unless the product is disassembled. Solid state electronics and computer circuitry have displaced many earlier mechanical solutions, no doubt improving product reliability and efficiency while reducing their price. Nevertheless, many of those displaced mechanical components have lives of their own and may very well turn up in other products in different form performing different functions after undergoing dimensional and material transformations. Classical, proven mechanisms and mechanical devices may seem to disappear only to reappear in other forms and applications. Anyone who believes that all mechanisms will be replaced by electronics need only examine the sophistication of the latest self-winding mechanical watches, digital cameras, gyro-stabilized vehicles, and navigational systems. This book illustrates the ongoing importance of classical mechanical devices as well as the latest mechatronic devices formed by the merger between mechanics and electronics. It is a must addition to your personal technical library, and it offers you a satisfy

欢迎使用命令参考。该参考包含完整的详细命令描述字典，按字母顺序排列。 它是正确使用命令的权威资源，它为每个命令的每个参数提供了全面的规范。 Welcome to the Command Reference.This reference contains a complete dictionary of detailed command descriptions, arranged in alphabetical order. It is the definitive resource for correct command usage, providing comprehensive specifications for every argument of every command. The Command Reference is intended to provide information about individual commands. Although the reference also contains lists of commands arranged by functional grouping, it is not intended to be your primary source of procedural information. For introductory information and procedural guidelines concerning when and where to use commands, see the appropriate analysis guide for your application. A command mentioned in the various analysis guides implies a link to the detailed command description given in this reference. For ordering purposes, the alphabetical ordering of commands that begin with a star (*) or a slash (/) ignores those symbols. A printed copy of the Commands Quick Reference Guide is available on the ANSYS Customer Portal in the documentation area. The following Command Reference topics are available: 1.1.

In the development of the basic stress equations for tension, compression, bending, and torsion, it was assumed that no geometric irregularities occurred in the member under consideration. But it is quite difficult to design a machine without permitting some changes in the cross sections of the members. Rotating shafts must have shoulders designed on them so that the bearings can be properly seated and so that they will take thrust loads; and the shafts must have key slots machined into them for securing pulleys and gears. A bolt has a head on one end and screw threads on the other end, both of which account for abrupt changes in the cross section. Other parts require holes, oil grooves, and notches of various kinds. Any discontinuity in a machine part alters the stress distribution in the neighborhood of the discontinuity so that the elementary stress equations no longer describe the state of stress in the part at these locations. Such discontinuities are called stress raisers, and the regions in which they occur are called areas of stress concentration. Stress concentrations can also arise from some irregularity not inherent in the member, such as tool marks, holes, notches, grooves, or threads. 1 in T 18 in Figure 3–28 The cross-section of a thin strip of steel subjected to a torsional moment T. bud29281_ch03_071-146.qxd 11/24/09 3:02PM Page 110 ntt 203:MHDQ196:bud29281:0073529281:bud29281_pagefiles: Load and Stress Analysis 111 A theoretical, or geometric, stress-concentration factor Kt or Kts is used to relate the actual maximum stress at the discontinuity to the nominal stress. The factors are defined by the equations K t = σ max σ0 K ts = τ max τ0 (3–48) where Kt is used for normal stresses and Kts for shear stresses. The nominal stress σ0 or τ0 is the stress calculated by using the elementary stress equations and the net area, or net cross section. Sometimes the gross cross section is used instead, and so it is always wise to double check the source of Kt or
