RISSingularities of a Manipulator With Offset Wrist
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The singularities of manipulators with offset wrists are difficult to enumerate. This article presents a numerical study to illuminate singularity problems when using an offset wrist with an ...
Cavitation Properties of Oils Under Dynamic Stressing by Tension
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We report measurements of the effective tensile strength Fc of commercial “multigrade” oils (in the SAE viscosity grades 5W-30 and 10W-40) over a range of temperatures T, which are representative ...
Mechanism Link Rotatability and Limit Position Analysis Using Polynomial Discriminants
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A theory is proposed for algebraically determining the limit positions of single-degree-of-freedom mechanisms. The absence of limit positions indicates that the link being considered is a fully ...

Maximizing Kinematic Motion for a 3-DOF VGT Module
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This article presents design results for maximizing kinematic motion range in three-degree-of-freedom (DOF) double-octahedral variable-geometry-truss (VGT) modules modeled as extensible gimbals. Design ...
Rheology of Dilute Polymer Solutions and Engine Lubricants in High Deformation Rate Extensional Flows Produced by Bubble Collapse
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We report a study of liquid jets formed by the collapse of bubbles under cavitation-generated pressure waves. Such jets involve an extensional flow which is characterized by high rates of ...
