Klappentext Classical and Modern Approaches in the Theory of Mechanisms is a study of mechanisms in the broadest sense, covering the theoretical background of mechanisms, their structures and components, their planar and spatial analysis, motion transmission, and technical approaches to kinematics, mechanical systems, and machine dynamics. In addition to classical approaches, the book presents two new methods: the analytic-assisted method using Turbo Pascal calculation programs, and the graphical-assisted method, outlining the steps required for the development of graphical constructions using AutoCAD; the applications of these methods are illustrated with examples. Aimed at students of mechanical engineering, and engineers designing and developing mechanisms in their own fields, this book provides a useful overview of classical theories and modern approaches to the practical and creative application of mechanisms, in seeking solutions to increasingly complex problems. Presents algorithms that transform CAD software into a machine-tool, and for the animation of planar and spatial mechanisms. Outlines the analytic-assisted method using Turbo Pascal calculation programs, and the graphical-assisted method using AutoCAD. Includes a companion website with links to computer programs requiring only an elementary knowledge of AutoCAD and related programs, found at www.wiley.com/go/pandmech17 Inhaltsverzeichnis Preface xi About the Companion Website xiii 1 The Structure of Mechanisms 1 1.1 Kinematic Elements 1 1.2 Kinematic Pairs 1 1.3 Kinematic Chains 2 1.4 Mobility of Mechanisms 3 1.4.1 Definitions 3 1.4.2 Mobility Degree of Mechanisms without Common Constraints 5 1.4.3 Mobility Degree of Mechanisms with Common Constraints 5 1.4.4 Mobility of a MechanismWritten with the Aid of the Number of Loops 7 1.4.5 Families of Mechanisms 7 1.4.6 Actuation of Mechanisms 9 1.4.7 Passive Elements 9 1.4.8 Passive Kinematic Pairs 10 1.4.9 Redundant Degree of Mobility 10 1.4.10 Multiple Kinematic Pairs 11 1.5 Fundamental Kinematic Chains 11 1.6 Multi-pairs (Poly-pairs) 14 1.7 Modular Groups 15 1.8 Formation and Decomposition of PlanarMechanisms 16 1.9 Multi-poles and Multi-polar Schemata 18 1.10 Classification of Mechanisms 18 2 Kinematic Analysis of Planar Mechanisms with Bars 21 2.1 General Aspects 21 2.2 Kinematic Relations 21 2.2.1 Plane-parallel Motion 21 2.2.2 Relative Motion 23 2.3 Methods for Kinematic Analysis 24 2.3.1 The Grapho-analytical Method 24 2.3.2 The Method of Projections 24 2.3.3 The Newton-Raphson Method 25 2.3.4 Determination of Velocities and Accel...
