RISEnjoying the Research Journey
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: At the Mechanisms & Robotics Awards Luncheon held September 2, 2009 in San Diego, CA, Dr. Larry L. Howell, Professor of Mechanical Engineering at Brigham Young University, received the 2009 ASME Mechanisms &...
Mitigating the Effects of Local Flexibility at the Built-In Ends of Cantilever Beams
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Local distortion at the built-in ends of cantilever beams can lead to significant errors when models assume the support to be perfectly rigid. This paper presents a novel approach for mitigating ...
Bistable 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 ...
Mechanical Design of Compliant Microsystems—A Perspective and Prospects
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The field of microsystems, or microelectromechanical systems (MEMS) as it is popularly known, is a truly multidisciplinary area of research. It combines a wide variety of physical, chemical, and ...
Design Space of Single-Loop Planar Folded Micro Mechanisms With Out-of-Plane Motion
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Microelectromechanical systems (MEMS) are usually fabricated using planar processing methods such as surface micromachining, bulk micromachining, or LIGA-type fabrication. If a micro mechanism is ...
A Three Degree-of-Freedom Model for Self-Retracting Fully Compliant Bistable Micromechanisms
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A three degree-of-freedom (3DOF) pseudo-rigid-body model (PRBM) has been developed and used in the design of a new class of self-retracting fully compliant bistable micromechanism (SRFBM). The ...
Evaluation and Comparison of Alternative Compliant Overrunning Clutch Designs
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Compliance criteria are used to evaluate the general class of over-running clutches to determine which type is best suited to benefit from compliance. The criteria used in the evaluation include ...
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 ...
Spherical Bistable Micromechanism
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A new micromechanism, the spherical bistable micromechanism (SBM), is described. The SBM has several advantageous features, which include two stable positions that require power only in transitioning ...
Components, Building Blocks, and Demonstrations of Spherical Mechanisms in Microelectromechanical Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Microelectromechanical systems (MEMS) are usually fabricated using planar processing methods, which complicates the design of devices capable of complex motions. For applications that need a ...
