Design optimization of planar mechanisms
… program was used to design two types of planar mechanisms - function generators and path generators. Miscellaneous design considerations and recommendations for future research are discussed.

Ortho-Planar Mechanisms for Microelectromechanical Systems
… for representing the design space of ortho-planar mechanisms has been developed. The method is based on the Theorem of Equality of Orientation Set Measures (TEOSM) which allows mechanisms to be represented by points in an abstract space. The method is first developed for single loop planar …

Synthesis of mechanisms for function, path, and motion generation using invariant characterization, storage and search methods
… an approach for the synthesis of four-bar planar mechanisms for function, path, and motion generation based upon the use of invariant descriptors and local database generation and search methods;Transformation and descriptor methods are used to characterize the motion of four-bar planar …

The design of adjustable spherical mechanisms using plane-to-sphere and sphere-to-plane projections
… of its links, the workspaces of spherical mechanisms (whether line segments, closed loops or area regions) are spherical in curvature. This characteristic of spherical mechanisms makes them quite effective and practical in motion path and function generation applications requiring spherical …

The Pseudo-Rigid-Body Model for Dynamic Predictions of Macro and Micro Compliant Mechanisms
… discusses the dynamic predictions of compliant mechanisms using the Pseudo-Rigid-Body model (PRBM). In order to improve the number of mechanisms that can be modeled, this research develops and identifies several key concepts in the behavior of beam segments where both ends are fixed to a rigid …

Método dimensional óptimo de sistemas multicuerpo con restricciones dinámicas: aplicación al diseño de mecanismos planos
… used to optimise the dynamic behaviour of planar mechanisms. The described method enables the simultaneous optimisation of the kinematic and dynamic behaviour of the system from the very earliest phases of design, thus making design tasks easier and shortening the design cycle of the system.

Kinematic synthesis of adjustable spatial four and five-bar mechanisms for finite and multiply separated positions
Although spatial mechanisms are more general in structure than planar mechanisms, their applications are few due to the limited number of practical design tools and the complexity of those available. It is in fact the task of the future to develop effective, but practical design tools for spatial …

Optimal synthesis of planar adjustable mechanisms
Adjustable mechanisms provide degrees of flexibility while retaining desirable features of one degree of freedom close-loop mechanisms, such as simplicity, stability, and high speed capabilities. By adjusting linkage parameters, additional phases of motions can be achieved using the same hardware. …

Zero modes of origami-inspired trusses
… or folding modes, of periodic structures or mechanisms. First, we introduce a first-order analytical method to find the zero modes of one cell in these patterns. By adding multipliers, this gives the trend throughout the pattern. We apply this method to a case study of two planar mechanisms: …

Kinematic Synthesis of Planar, Shape-Changing Rigid Body Mechanisms for Design Profiles with Significant Differences in Arc Length
… of ergonomic needs. Rigid body shape-change mechanisms offer many advantages including the high capacity to endure substantial loads while achieving large displacements. Their design techniques are also well-established. The goal of this research project is to develop the synthesis theory to …
