RISPseudo-Rigid-Body Modeling of a Single Vertex Compliant-Facet Origami Mechanism
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recently, there has been an increased interest in origami art from a mechanism design perspective. The deployable nature and the planar fabrication method inherent to origami provide potential for space and cost-efficient ...
Static Balancing of Four-Bar Compliant Mechanisms With Torsion Springs by Exerting Negative Stiffness Using Linear Spring At the Instant Center of Rotation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A design approach for the quasi-static balancing of four-bar linkages with torsion springs is proposed. Such an approach is useful in the design of quasi-statically balanced fully compliant mechanisms by tuning the stiffness ...
Symmetric Kinetostatic Behavior From Asymmetric Spatially Curved Beams
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A cantilevered rod’s endpoint has a symmetric stiffness profile throughout its range of motion. Generally, this is not the case for spatially curved compliant beams, particularly if they are asymmetric, i.e., their fixation ...
A Monolithic Force-Balanced Oscillator
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Usage of compliant micromechanical oscillators has increased in recent years, due to their reliable performance despite the growing demand for miniaturization. However, ambient vibrations affect the momentum of such ...
Symmetric Kinetostatic Behavior From Asymmetric Spatially Curved Beams
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A cantilevered rod’s endpoint has a symmetric stiffness profile throughout its range of motion. Generally, this is not the case for spatially curved compliant beams, particularly if they are asymmetric, i.e., their fixation ...
Statically Balancing a Reconfigurable Mechanism by Using One Passive Energy Element Only: A Case Study
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents the static balancing design of a special reconfigurable linkage that can switch between two one-degree-of-freedom (DoF) working configurations. We will show that the studied dual-mode linkage only ...
Shape Optimization Framework for the Path of the Primary Compliance Vector in Compliant Mechanisms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The primary compliance vector (PCV) captures the dominant kinematic behavior of a compliant mechanism. Its trajectory describes large deformation mechanism behavior and can be integrated in an optimization objective in ...
Toward a Unified Design Approach for Both Compliant Mechanisms and Rigid Body Mechanisms: Module Optimization
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Rigidbody mechanisms (RBMs) and compliant mechanisms (CMs) are traditionally treated in significantly different ways. In this paper, we present a synthesis approach that is appropriate for both RBMs and CMs. In this approach, ...
Experimental Validation of Jacobian Based Stiffness Analysis Method for Parallel Manipulators With Nonredundant Legs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A complete stiffness analysis of a parallel manipulator considers the structural compliance of all elements, both in designed degreesoffreedom (DoFs) and constrained DoFs, and also includes the effect of preloading. This ...
Modeling of a Flexible Instrument to Study its Sliding Behavior Inside a Curved Endoscope
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Flexible instruments are increasingly used to carry out surgical procedures. The instrument tip is remotely controlled by the surgeon. The flexibility of the instrument and the friction inside the curved endoscope jeopardize ...
