MOBILITY ANALYSIS AND TOPOLOGY SYNTHESIS OF COMPLIANT MECHANISM USING COMPLIANCE NUMBER AND PSEUDO-RIGID-BODY MODEL (PRBM)
… number (C) and the pseudo-rigid-body model (PRBM) concepts are then used to determine the degrees of freedom and the possible mode shapes for a given compliant mechanism. Furthermore, research is conducted for better characterization of the kinematic behavior of a compliant mechanism. In the …

The Pseudo-Rigid-Body Model for Dynamic Predictions of Macro and Micro Compliant Mechanisms
… 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 body (fixed-fixed flexible segments). A model …

Compliant ortho-planar spring behavior under complex loads
… design tools, such as pseudo-rigid-body models (PRBM) for COPS, are discussed. A new 3D PRBM is presented along with a discussion on the possible applications of such to a rotating COPS. Stress stiffening and lateral stability are two major phenomena occurring in a rotating COPS. Both phenomena …

Large-Displacement Linear-Motion Compliant Mechanisms
… element. It presents a pseudo-rigid-body model (PRBM) for rolling-contact compliant beams (RCC beams), a compliant element used in the RCC suspension. The loading conditions and boundary conditions for RCC beams can be simplified to an equivalent cantilever beam that has the same force-deflection …

Compliant Centrifugal Clutches: Design, Analysis, and Testing
… were reviewed. The pseudo-rigid-body model (PRBM), rigid-body replacement synthesis, force-deflection analysis, compliance potential evaluation, and compliant concept evaluation were used to develop effective new centrifugal clutch concepts. These methods helped develop and model four novel …

Design of non-serial, non-parallel flexural transmissions as applied to a micro-machined MEMS tuning fork gyroscope
… Topologies (FACT), pseudo-rigid body modeling (PRBM), and constraint based-design (CBD) to include directionality. Flexural transmissions may be used to couple the motion of a plurality of stages to have different types (translations, rotations, and screws), different transmission ratios, and …

Development and Design of Constant-Force Mechanisms
This thesis adds to the knowledge base of constant-force mechanisms (CFMs). It begins by reviewing past work done in the area of CFMs and then develops new nondimensionalized parameters that are used to simplify the calculations required to design a CFM. Comparison techniques are then developed …

Achieving Complex Motion with Fundamental Components for Lamina Emergent Mechanisms
<p>Designing mechanical products in a competitive environment can present unique challenges, and designers constantly search for innovative ways to increase efficiency. One way to save space and reduce cost is to use ortho-planar compliant mechanisms which can be made from sheets of material, or …
