Development and Analysis of a Long-Stroke Spring Guiding System
(The American Society of Mechanical Engineers (ASME), 2004)Inspired by the operating principle of a tank’s track, we have developed a long-stroke spring guiding system with belt-shaped springs. Other than those characteristics of normal spring guides, ... -
A Study of Fuel Efficiency and Emission Policy Impact on Optimal Vehicle Design Decisions
(The American Society of Mechanical Engineers (ASME), 2004)Recent environmental legislation, such as the European Union Directive on End-of-Life Vehicles and the Japanese Home Electric Appliances Recycling law, has had a major influence on product design ... -
Increased Surface Fatigue Lives of Spur Gears by Application of a Coating
(The American Society of Mechanical Engineers (ASME), 2004)Hard coatings have potential for increasing gear surface fatigue lives. Experiments were conducted using gears both with and without a metal-containing, carbon-based coating. The gears were ... -
A Kinematics and Power Flow Analysis Methodology for Automatic Transmission Planetary Gear Trains
(The American Society of Mechanical Engineers (ASME), 2004)A generalized formulation for analyzing speeds and forces of the gear components of planetary automatic transmissions is proposed. The formulation is capable of analyzing any typical one-degree-of-freedom ... -
Finding the Shortest Path on a Polyhedral Surface and Its Application to Quality Assurance of Electric Components
(The American Society of Mechanical Engineers (ASME), 2004)This paper presents a computational method for finding the shortest path along polyhedral surfaces. This method is useful for verifying that there is a sufficient distance between two electrical ... -
Synthesis, Design, and Prototyping of a Planar Three Degree-of-Freedom Reactionless Parallel Mechanism
(The American Society of Mechanical Engineers (ASME), 2004)This paper addresses the dynamic balancing of a planar three-degree-of-freedom parallel mechanism. A mechanism is said to be dynamically balanced if, for any motion of the mechanism, the reaction ... -
Graphical Technique to Locate the Center of Curvature of a Coupler Point Trajectory
(The American Society of Mechanical Engineers (ASME), 2004)This paper presents an original technique to locate the center of curvature of the path traced by an arbitrary point fixed in the coupler link of a planar four-bar linkage. The method is ... -
Direct Singular Positions of 3RPS Parallel Manipulators
(The American Society of Mechanical Engineers (ASME), 2004)In this study a procedure to obtain direct singular positions of a 3RPS parallel manipulator is presented. If the heights of three spherical joints, denoted by d1n,d2n, and d3n respectively, ... -
Dynamic Topology Optimization of Compliant Mechanisms and Piezoceramic Actuators
(The American Society of Mechanical Engineers (ASME), 2004)A topology optimization method is developed to design a piezoelectric ceramic actuator together with a compliant mechanism coupling structure for dynamic applications. The objective is to maximize ... -
A Hybrid Fuzzy Simplex Genetic Algorithm
(The American Society of Mechanical Engineers (ASME), 2004)This paper presents a novel hybrid genetic algorithm that has the ability of the genetic algorithms to avoid being trapped at local minimum while accelerating the speed of local search by ... -
Design of a Passively Balanced Spatial Linkage Haptic Interface
(The American Society of Mechanical Engineers (ASME), 2004)This paper describes the design and implementation of a compact high fidelity desktop haptic interface that provides three-degree-of-freedom point-force interaction through a handheld pen-like stylus. ... -
Analysis of Active Joint Failure in Parallel Robot Manipulators
(The American Society of Mechanical Engineers (ASME), 2004)In this study, the effect of active joint failure on the mobility, velocity, and static force of parallel robot manipulators is investigated. Two catastrophic active joint failure types are ... -
Kinematics of the Translational 3-URC Mechanism1
(The American Society of Mechanical Engineers (ASME), 2004)The use of less than six degrees of freedom (dof) mechanisms instead of six-dof ones is always recommended when the application makes it possible, since their architectures and control are ... -
On Rationality in Engineering Design
(The American Society of Mechanical Engineers (ASME), 2004)Rationality has different meanings within different contexts. In engineering design, to be rational usually means to be instrumentally rational, that is, to take a measured decision aimed at the ... -
Multi-Attribute Decision Making Using Hypothetical Equivalents and Inequivalents
(The American Society of Mechanical Engineers (ASME), 2004)In this paper, the problem of selecting from among a set of alternatives using multiple, potentially conflicting criteria is discussed. A number of approaches are commonly used to make these ... -
A Simple Procedure for Modifying High-Speed Cam Profiles for Vibration Reduction
(The American Society of Mechanical Engineers (ASME), 2004)Unwanted vibration in cam-follower systems causes increased forces, noise, wear, and operating costs. This paper investigates the use of input shaping on cam profiles to reduce vibration. Input ... -
Conceptual Design of a Long-Strike Ultra-Precision Actuator
(The American Society of Mechanical Engineers (ASME), 2004)A conceptual long-strike ultra-precision actuator is proposed with this article. The design method is inspired by the unique relationship of voltage versus displacement with a coil-wound potentiometer. ... -
