Advanced Theory of Constraint and Motion Analysis for Robot Mechanisms provides a complete analytical approach to the invention of new robot mechanisms and the analysis of existing designs based on a unified mathematical description of the kinematic and geometric constraints of mechanisms.

Beginning with a high level introduction to mechanisms and components, the book moves on to present a new analytical theory of terminal constraints for use in the development of new spatial mechanisms and structures. It clearly describes the application of screw theory to kinematic problems and provides tools that students, engineers and researchers can use for investigation of critical factors such as workspace, dexterity and singularity.

Combines constraint and free motion analysis and design, offering a new approach to robot mechanism innovation and improvement Clearly describes the use of screw theory in robot kinematic analysis, allowing for concise representation of motion and static forces when compared to conventional analysis methods Includes worked examples to translate theory into practice and demonstrate the application of new analytical methods to critical robotics problems

The Age of Silver advances a "horizontal" method of comparative literature and applies this approach to analyze the multiple emergences of early realism and novelistic modernity in Eastern and Western cultural spheres from the sixteenth through the eighteenth centuries. Naming this era of economic globalization the Age of Silver, Ning Ma emphasizes the bullion flow from South America and Japan to China through international commerce, and argues that the resultant transcontinental monetary and commercial co-evolutions stimulated analogous socioeconomic shifts and emergent novelistic realisms. The main texts addressed within include The Plum in the Golden Vase (China), Don Quixote (Spain), The Life of an Amorous Man (Japan), and Robinson Crusoe (England). These Eastern and Western narratives indicate from their own geographical vantage points commercial expansions' stimulation of social mobility and larger processes of cultural destabilization. Their realist tendencies are underlain with politically critical functions and connote "heteroglossic" national imaginaries. This horizontal argument realigns novelistic modernity with a multipolar global context and reestablishes commensurabilities between Eastern and Western literary histories. The Age of Silver challenges the unilateral equation between globalization and modernity with westernization, and foregrounds a polycentric mode of global early modernity for pluralizing the genealogy of world literature and historical transcultural relations.

Over the last 15 years, the application of innovative steel concepts in the automotive industry has increased steadily. Numerical simulation technology of hot forming of high-strength steel allows engineers to modify the formability of hot forming steel metals and to optimize die design schemes. Theories, Methods and Numerical Technology of Sheet Metal Cold and Hot Forming focuses on hot and cold forming theories, numerical methods, relative simulation and experiment techniques for high-strength steel forming and die design in the automobile industry.Theories, Methods and Numerical Technology of Sheet Metal Cold and Hot Forming introduces the general theories of cold forming, then expands upon advanced hot forming theories and simulation methods, including:the forming process,constitutive equations,hot boundary constraint treatment, andhot forming equipment and experiments.Various calculation methods of cold and hot forming, based on the authors’ experience in commercial CAE software for sheet metal forming, are provided, as well as a discussion of key issues, such as hot formability with quenching process, die design and cooling channel design in die, and formability experiments.Theories, Methods and Numerical Technology of Sheet Metal Cold and Hot Forming will enable readers to develop an advanced knowledge of hot forming, as well as to apply hot forming theories, calculation methods and key techniques to direct their die design. It is therefore a useful reference for students and researchers, as well as automotive engineers.

Planar linkages play a very important role in mechanical engineering. As the simplest closed chain mechanisms, planar four-bar linkages are widely used in mechanical engineering, civil engineering and aerospace engineering.Design of Special Planar Linkages proposes a uniform design theory for planar four-bar linkages. The merit of the method proposed in this book is that it allows engineers to directly obtain accurate results when there are such solutions for the specified n precise positions; otherwise, the best approximate solutions will be found. This book discusses the kinematics and reachable workspace and singularity of a planar 3-RRR linkage, which can be used to analyze other planar linkages. Then a foldable stair that retains the walking conversions of human beings and all the merits of a concrete stair in civil engineering is described along with a lifting guidance mechanism that has the advantages of high strength, high rigidity, lightweight overconstraint trusses and motion flexibility. The method proposed in this book can be applied to other planar linkages.This book offers a valuable resource for scientists, researchers, engineers, graduate students in mechanical engineering especially those interested in engineering design, robotics and automation.Jingshan Zhao, Associate professor; Zhijing Feng and Fulei Chu, professor; Ning Ma, Dr., all work at the Department of Mechanical Engineering, Tsinghua University.
