Book Description
Mechanism constitute the mechanical organs of machines. They are generally composed of rigid segments connected to each other by articulated joints. The function of the joints is to act as bearings, i.e. to constraint the relative motion of the segments it connects, while leaving a freedom of motion in some specific directions. Conventional mechanisms rely on sliding or rolling motions between solid bodies in order to fulfill the bearing function. Consequently, these bearings exhibit friction forcers limiting the motion precision, they require lubrication, they undergo wear, they produce debris and they have a limited lifetime. Flexure mechanisms rely on a radically different physical principle to fulfill the bearing function : the elastic deformation of beams and membranes. This gets around the above-mentioned limitations. The rigid segments of the mechanism are connected to each other via elastically deformable joints called flexures which are springs whose stiffnesses are designed to be very high in the directions where the joint has to constrain relative motion and very flexile in the directions where freedom of motion is required. As a result, mechanisms can be manufactured monolithically and, by proper choice of materials and geometry of the flexures, lead to lifetimes of tens of millions of cycles without any wear or change in the geometry or forces of motion. Thanks to these unique properties flexure mechanisms have become an inescapable technology in all environments where friction, lubrication, wear, debris or mechanical backlash are forbidden : outer space, vacuum, cryogenics, high radiation, ultra-clean environments, etc. This book comes within the scope of this technological evolution. It gathers the knowledge of experts in flexure mechanisms design having worked in the key fields of high precision robotics, aerospace mechanisms, particle accelerators and watch making industry. It is dedicated to engineers, scientists and students working in these fields. The book presents the basic principles underlying flexure mechanism design, the most important flexures and the key formulas for their proper design. It also covers more general aspects of the kinematic design of multi-degrees of freedom mechanism exploiting the state of the art approaches of parallel kinematics. A wide variety of concrete examples of systems designed based on theses approaches are presented in details. in the directions where the joint has to constrain relative motion and very flexile in the directions where freedom of motion is required.

Book Description
This book serves as an introduction to the design and analysis of mechanisms using computer-aided design tools. A mechanism is a set of components connected together in such a way as to produce a desired motion. Examples of mechanisms in everyday life are numerous, and include windshield wipers, mechanical watch movements, the piston/connecting-rod/crankshaft assembly in an automotive engine and the fancy "European hinges" found in upscale kitchen cabinets. In each of these instances, the designer was confronted with the problem of producing a desired motion (e.g. sweeping a wiper across a windshield) in the most economical way. Until the recent past, mechanical designers have employed drafting tools (triangle, T-square, compass) to complete their work. These tools have been entirely superseded by computer-aided design tools such as CAD software (e.g. SOLIDWORKS®) and mathematical simulation software (e.g. MATLAB®). While a mechanical engineer might use a pencil and sketch pad to help in brainstorming a design, the final result will inevitably be developed and communicated through software. With this in mind, we have written a textbook that brings the modern practice of mechanical design into the classroom and computer lab. The book is intended to accompany a one-semester course in mechanical design at a four-year university or technical college. The authors have used the material in this textbook to teach mechanical design to first, second and third-year students for almost 20 years at our university. The text demonstrates the use of modern design tools (e.g. MATLAB® and SOLIDWORKS®) to conduct motion and force analysis of mechanisms. Practical design examples are given throughout the book, and mobile-friendly web content is fully-integrated.

Book Description
Traditionally, mechanisms are created by designer's intuition, ingenuity, and experience. However, such an ad hoc approach cannot ensure the identification of all possible design alternatives, nor does it necessarily lead to optimum design. Mechanism Design: Enumeration of Kinematic Structures According to Function introduces a methodology for systematic creation and classification of mechanisms. With a partly analytical and partly algorithmic approach, the author uses graph theory, combinatorial analysis, and computer algorithms to create kinematic structures of the same nature in a systematic and unbiased manner. He sketches mechanism structures, evaluating them with respect to the remaining functional requirements, and provides numerous atlases of mechanisms that can be used as a source of ideas for mechanism and machine design. He bases the book on the idea that some of the functional requirements of a desired mechanism can be transformed into structural characteristics that can be used for the enumeration of mechanisms. The most difficult problem most mechanical designers face at the conceptual design phase is the creation of design alternatives. Mechanism Design: Enumeration of Kinematic Structures According to Function presents you with a methodology that is not available in any other resource.
