An Experimental Investigation of Spur Gear Efficiency
(The American Society of Mechanical Engineers (ASME), 2008)In this study, a test methodology was developed for the measurement of spur gear efficiency under high-speed and variable torque conditions. A power-circulating test machine was designed to ... -
A Graph-Based Fault Identification and Propagation Framework for Functional Design of Complex Systems
(The American Society of Mechanical Engineers (ASME), 2008)In this paper, the functional-failure identification and propagation (FFIP) framework is introduced as a novel approach for evaluating and assessing functional-failure risk of physical systems ... -
Flank Correction for Spiral Bevel and Hypoid Gears on a Six-Axis CNC Hypoid Generator
(The American Society of Mechanical Engineers (ASME), 2008)Because the contact patterns of spiral bevel and hypoid gears are highly sensitive to tooth flank geometry, it is desirable to reduce the flank deviations caused by machine errors and heat ... -
A Geometric Design Model for the Circolimaçon Positive Displacement Machine
(The American Society of Mechanical Engineers (ASME), 2008)A circolimaçon positive displacement machine is driven by a limaçon mechanism, but the profiles of its rotor and housing are circular arcs. As such, its design models are different ... -
A Virtual Cam Method for Locating Instant Centers of Kinematically Indeterminate Linkages
(The American Society of Mechanical Engineers (ASME), 2008)Kinematically indeterminate linkages are those whose complete set of instant centers cannot be obtained by Kennedy’s theorem. A linkage of this kind is often characterized as having no four-bar ... -
Closed-Loop Analysis in Semantic Tolerance Modeling
(The American Society of Mechanical Engineers (ASME), 2008)A semantic tolerance modeling scheme based on generalized intervals was recently proposed to allow for embedding more tolerancing intents in specifications with a combination of numerical intervals ... -
Rational Motion Interpolation Under Kinematic Constraints of Spherical 6R Closed Chains
(The American Society of Mechanical Engineers (ASME), 2008)The work reported in this paper brings together the kinematics of spherical closed chains and the recently developed free-form rational motions to study the problem of synthesizing rational ... -
Static Equilibrium of Spatial Mechanisms With Cylindrical Joints
(The American Society of Mechanical Engineers (ASME), 2008)The components of force and torque acting on a joint of a link in static equilibrium are partitioned according to the type of joint so that the equations of static equilibrium can be set ... -
A Family of Kinematically Redundant Planar Parallel Manipulators
(The American Society of Mechanical Engineers (ASME), 2008)Parallel manipulators feature relatively high payload and accuracy capabilities compared to their serial counterparts. However, they suffer from small workspace and low maneuverability. Kinematic ... -
Risk-Based Resource Allocation for Collaborative System Design in a Distributed Environment
(The American Society of Mechanical Engineers (ASME), 2008)Risk analysis is important in system design because of its essential role in evaluating functional reliability and mitigating system failures. In this work, we aim at expanding existing risk ... -
Type Synthesis of Six-DOF Wrist-Partitioned Parallel Manipulators
(The American Society of Mechanical Engineers (ASME), 2008)A six-DOF wrist-partitioned parallel manipulator is a parallel manipulator in which three of the six actuated joints are used to control the position of a point on the moving platform while ... -
Engineering Product Design Optimization for Retail Channel Acceptance
(The American Society of Mechanical Engineers (ASME), 2008)Significant recent research has focused on the marriage of consumer preferences and engineering design in order to improve profitability. The extant literature has neglected the effects of marketing ... -
Geometric Modeling and Optimization of Multimaterial Compliant Mechanisms Using Multilayer Wide Curves
(The American Society of Mechanical Engineers (ASME), 2008)Multimaterial compliant mechanisms enhance the performance of regular single-material compliant mechanisms by adding a new design option, material type variation. This paper introduces a geometric ... -
Higher-Order Tooth Flank Form Error Correction for Face-Milled Spiral Bevel and Hypoid Gears
(The American Society of Mechanical Engineers (ASME), 2008)The increasing demand for low noise and high strength leads to higher quality requirements in manufacturing spiral bevel and hypoid gears. Due to heat treatment distortions, machine tolerances, ... -
June Editorial
(The American Society of Mechanical Engineers (ASME), 2008)A journal like JMD is the product of an extensive collaboration of many individuals: authors, editors, editorial staff, and production staff. As technical editor, an important role for me is ... -
Representation of Topological Changes in Metamorphic Mechanisms With Matrices of the Same Dimension
(The American Society of Mechanical Engineers (ASME), 2008)This short paper introduces a new adjacency matrix to represent the topological changes of metamorphic mechanisms. An element “−1” is introduced to indicate the frozen kinematic pairs, which ... -
