RISBistable Configurations of Compliant Mechanisms Modeled Using Four Links and Translational Joints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Bistable mechanical devices remain stable in two distinct positions without power input. They find application in valves, switches, closures, and clasps. Mechanically bistable behavior results from ...
Identification of Compliant Pseudo-Rigid-Body Four-Link Mechanism Configurations Resulting in Bistable Behavior
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Bistable mechanisms, which have two stable equilibria within their range of motion, are important parts of a wide variety of systems, such as closures, valves, switches, and clasps. Compliant ...
Compliant Wireform Mechanisms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an alternative to fabrication methods commonly used in compliant mechanisms research, resulting in a new class of compliant mechanisms called wireform mechanisms. This technique ...
Modeling and Experiments of Buckling Modes and Deflection of Fixed-Guided Beams in Compliant Mechanisms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper explores the deflection and buckling of fixed-guided beams used in compliant mechanisms. The paper’s main contributions include the addition of an axial deflection model to existing ...
A Pseudo-Rigid-Body Model for Initially-Curved Pinned-Pinned Segments Used in Compliant Mechanisms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The pseudo-rigid-body model concept allows compliant mechanisms to be analyzed using well-known rigid-body kinematics. This paper presents a pseudo-rigid-body model for initially curved pinned-pinned ...
Modeling and Experimental Validation of DNA Motion in Uniform and Nonuniform DC Electric Fields
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We are developing a new technique to insert foreign DNA into a living cell using a microelectromechanical system. This new technique relies on electrical forces to move DNA in a nonuniform ...
A Tristable Mechanism Configuration Employing Orthogonal Compliant Mechanisms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Tristable mechanisms, or devices with three distinct stable equilibrium positions, have promise for future applications, but the complexities of the tristable behavior have made it difficult to ...
Cylindrical Single-Degree-of-Freedom Spatial Mechanisms for Cell Restraint
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Many transgenic animal production techniques require egg cells to be held in place during injection of the transgene. This paper presents a micro-electromechanical systems (MEMS) mechanism that ...
Design and Testing of a Thin-Flexure Bistable Mechanism Suitable for Stamping From Metal Sheets
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We present a new technique for fabricating compliant mechanisms from stamped metal sheets. The concept works by providing thinned segments to allow rotation of flexural beams 90 deg about their ...
A Numerical Method for Position Analysis of Compliant Mechanisms With More Degrees of Freedom Than Inputs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An underactuated or underconstrained compliant mechanism may have a determined equilibrium position because its energy storage elements cause a position of local minimum potential energy. The ...
