Improving Machine Drive Dynamics: A Structured Design Approach Toward Balancing
(The American Society of Mechanical Engineers (ASME), 2008)Linkage and cam-follower mechanism design are often based on the simplifying assumption of constant drive speed. Usually, however, the mutual interaction between the mechanism and its actuator ... -
A View of Design Research
(The American Society of Mechanical Engineers (ASME), 2008)The National Science Foundation (NSF) is an independent federal agency created by the US Congress in 1950 “to promote the progress of science; to advance the national health, prosperity, and ... -
Application of a Ground Beam-Joint Topology Optimization Method for Multi-Piece Frame Structure Design
(The American Society of Mechanical Engineers (ASME), 2008)When a multipiece frame structure is designed, not only its topological layout but also assembly locations should be determined. This paper presents a compliance-minimizing topology optimization ... -
Point-Line Distance Under Riemannian Metrics
(The American Society of Mechanical Engineers (ASME), 2008)A point-line is the combination of a directed line and an endpoint on the line. A pair of point-line positions corresponds to a point-line displacement, which is known to be associated with ... -
Synthesis and Analysis of Kinematics/Statics of a Novel 2SP̱S+SP̱R+SP Parallel Manipulator
(The American Society of Mechanical Engineers (ASME), 2008)This paper proposes a systematic methodology for dimension synthesis, kinematics, and statics of a novel 2SP̱S+SP̱R+SP parallel manipulator with 3DOF. First, a workspace is varied and analyzed ... -
Self-Collision Detection in Spatial Closed Chains
(The American Society of Mechanical Engineers (ASME), 2008)A novel methodology for detecting self-collisions in spatial closed kinematic chains is presented. In general these chains generate complex three dimensional motions in which their own links will ... -
On the Generation of Analytical Noncircular Multilobe Internal Pitch Curves
(The American Society of Mechanical Engineers (ASME), 2008)A method for the design of general analytical noncircular multilobe internal pitch curves is presented. The method is based on a reshaping algorithm. A selected monotonic function can be assigned ... -
On the Input Joint Rotation Space and Mobility of Linkages
(The American Society of Mechanical Engineers (ASME), 2008)This paper presents the concept and application of input joint rotation space of linkages and offers updates on the N-bar rotatability laws. A thorough discussion on the joint rotation space ... -
Product and Process Tolerance Allocation in Multistation Compliant Assembly Using Analytical Target Cascading
(The American Society of Mechanical Engineers (ASME), 2008)Tolerance allocation is the process of determining allowable dimensional variations in products (parts and subassemblies) and processes (fixtures and tools) in order to meet final assembly quality ... -
Optimal, Model-Based Design of Soft Robotic Manipulators
(The American Society of Mechanical Engineers (ASME), 2008)Soft robotic manipulators, unlike their rigid-linked counterparts, deform continuously along their lengths similar to elephant trunks and octopus arms. Their excellent dexterity enables them to ... -
A Concept for a Material That Softens With Frequency
(The American Society of Mechanical Engineers (ASME), 2008)This work presents design concepts to synthesize composite materials with special dynamic properties, namely, materials that soften at high frequencies. Such dynamic properties are achieved through ... -
Globalization and Internationalism
(The American Society of Mechanical Engineers (ASME), 2008)There has always been something ambivalent to me in Thomas Friedman’s famed dictum “The Earth is flat.” Earlier this year I had the opportunity to visit the Indian Institute of Science in ... -
A Variable Fidelity Model Management Framework for Designing Multiphase Materials
(The American Society of Mechanical Engineers (ASME), 2008)Research applications involving design tool development for multi phase material design are at an early stage of development. The computational requirements of advanced numerical tools for simulating ... -
Face Gear Width Prediction Using the DOE Method
(The American Society of Mechanical Engineers (ASME), 2008)This paper deals with face gear design. The goal is to propose a simple formula for predicting the width of the wheel as a function of the main design parameters. A specific software was ... -
Unified Uncertainty Analysis by the First Order Reliability Method
(The American Society of Mechanical Engineers (ASME), 2008)Two types of uncertainty exist in engineering. Aleatory uncertainty comes from inherent variations while epistemic uncertainty derives from ignorance or incomplete information. The former is usually ... -
Dynamic Performance and Modular Design of Redundant Macro-/Minimanipulators
(The American Society of Mechanical Engineers (ASME), 2008)This paper presents methodologies for the analysis and design of redundant manipulators, especially macro-/ministructures, for improved dynamic performance. Herein, the dynamic performance of a ... -
