A Co-Evolution Model for Prediction and Synthesis of New Products and Manufacturing Systems
(The American Society of Mechanical Engineers (ASME), 2012)A model for predicting the future codevelopment of new products and manufacturing systems is presented. The model incorporates a set of manufacturing co-evolution hypotheses that promote association ... -
Modeling and Design of Air Vane Motors for Minimal Torque Ripples
(The American Society of Mechanical Engineers (ASME), 2012)This paper presents the analysis and design of a novel air vane motor. Air motors have a very high specific power. They require compressed air rather than electricity to produce motion; thus, ... -
The Spring-Connected Rigid Block Model Based Automatic Synthesis of Planar Linkage Mechanisms: Numerical Issues and Remedies
(The American Society of Mechanical Engineers (ASME), 2012)Because it is difficult to select in advance an appropriate linkage for converting an input motion to a desired output motion, a linkage synthesis method that does not require any baseline ... -
A Contribution to the Design of Robust Profile Modifications in Spur and Helical Gears by Combining Analytical Results and Numerical Simulations
(The American Society of Mechanical Engineers (ASME), 2012)This paper addresses the definition of robust profile modifications in spur and helical gears. An original methodology is introduced which relies on closed-form analytical results on transmission ... -
Real Design Matters
(The American Society of Mechanical Engineers (ASME), 2012)If you missed the recent U.S. White House initiative on the Advanced Manufacturing Partnership (AMP), you shouldn’t have missed it. If you read the story carefully, you will find that it is ... -
Design of a Spherically Actuated Human Interaction Robot Head
(The American Society of Mechanical Engineers (ASME), 2012)This paper presents the development of a mechanism for actuating a sphere holonomically about 3 degrees of freedom (DOF). The target application is a robot head for mounting inside a vehicle ... -
Conceptual Design Method for Reducing Brake Squeal in Disk Brake Systems Considering Unpredictable Usage Factors
(The American Society of Mechanical Engineers (ASME), 2012)Minimizing brake squeal is one of the most important issues in the development of high performance braking systems. Furthermore, brake squeal occurs due to the changes in unpredictable factors ... -
A Novel Large-Range XY Compliant Parallel Manipulator With Enhanced Out-of-Plane Stiffness
(The American Society of Mechanical Engineers (ASME), 2012)There is an increasing need for compact large-range XY compliant parallel manipulators (CPMs). This paper deals with a novel large-range XY CPM with enhanced out-of-plane stiffness (LRXYCPMEOS). ... -
Coupling Mechanics of Antikythera Gearwheels
(The American Society of Mechanical Engineers (ASME), 2012)This paper discusses the gear coupling mechanics of the ancient Antikythera mechanism, among whose distinctive characteristics was the triangular shaping of the teeth. The engagement of the tooth ... -
Kinematics of Roller Migration in the Planetary Roller Screw Mechanism
(The American Society of Mechanical Engineers (ASME), 2012)This paper develops a kinematic model to predict the axial migration of the rollers relative to the nut in the planetary roller screw mechanism (PRSM). This axial migration is an undesirable ... -
Differential Contact Path and Conjugate Properties of Planar Gearing Transmission
(The American Society of Mechanical Engineers (ASME), 2012)This paper presents a general conjugation model based on the intrinsic kinematical properties of the contact path. The model is truly general for any planar transmission through contact curves, ... -
Reliability Analysis by Mean-Value Second-Order Expansion
(The American Society of Mechanical Engineers (ASME), 2012)In this paper, two second-order methods are proposed for reliability analysis. First, general random variables are transformed to standard normal random variables. Then, the limit-state function ... -
Design of an Active Ankle-Foot Prosthesis Utilizing a Four-Bar Mechanism
