Description
With a pioneering methodology, the book covers the fundamental aspects of kinematic analysis and synthesis of linkage, and provides a theoretical foundation for engineers and researchers in mechanisms design. The first book to propose a complete curvature theory for planar, spherical and spatial motion Treatment of the synthesis of linkages with a novel approach Well-structured format with chapters introducing clearly distinguishable concepts following in a logical sequence dealing with planar, spherical and spatial motion Presents a pioneering methodology by a recognized expert in the field and brought up to date with the latest research and findings Fundamental theory and application examples are supplied fully illustrated throughout
Reviews / Votes
"After reading this book, the reader will be convinced that the intended audience for it consists of researchers in differential geometry and discrete kinematic geometry, particularly in multi- dimensional space and in the kinematics of manipulators with multiple degrees of freedom. The book is useful also for scientists and engineers as well as graduate and Ph.d students interested in the theory and applications of multibody systems." (Zentralblatt MATH 2016)More details
