An Approach for the Gear Rolling Contact Fatigue Acceleration
(The American Society of Mechanical Engineers (ASME), 2016)This study proposes an approach for the acceleration of the experimental gear rolling contact fatigue (RCF) crack formation. By increasing the rotational velocity of a gear pair, the RCF experimental time period is reduced. ... -
An Evaluation Methodology for Design Concept Communication Using Digital Prototypes
(The American Society of Mechanical Engineers (ASME), 2016)Digital prototypes (DPs) allow designers to communicate design concepts to users by rendering physical characteristics of the concepts. To enhance user understanding of the concepts, it is important that the users be able ... -
Compensated Conjugation and Gear Tooth Modification Design
(The American Society of Mechanical Engineers (ASME), 2016)This paper addresses the fundamental issue on the conjugation for any gearing systems after tooth modification. It presents a rigorous theory on compensated conjugation for gear transmission error (TE) balance. The basic ... -
Effect of Social Structuring in Self Organizing Systems
(The American Society of Mechanical Engineers (ASME), 2016)Dealing with unforeseeable changing situations, often seen in exploratory and hazardous task domains, requires systems that can adapt to changing tasks and varying environments. The challenge for engineering design researchers ... -
Design Heuristics in Innovative Products
(The American Society of Mechanical Engineers (ASME), 2016)Current design theory lacks a systematic method to identify what designers know that helps them to create innovative products. In the early stages of idea generation, designers may find novel ideas come readily to mind, ... -
Design Optimization of Dynamically Coupled Actuated Butterfly Valves Subject to a Sudden Contraction
(The American Society of Mechanical Engineers (ASME), 2016)In this effort, we present novel nonlinear modeling of two solenoid actuated butterfly valves subject to a sudden contraction and then develop an optimal configuration in the presence of highly coupled nonlinear dynamics. ... -
Design for the Developing World: Common Pitfalls and How to Avoid Them
(The American Society of Mechanical Engineers (ASME), 2016)Engineers face many challenges when designing for the developing world, which are not typically encountered in other design circumstances, such as a lack of understanding of language, culture, and context. These challenges ... -
Enhanced Formulae for Determining Both Free Length and Rate of Cylindrical Compression Springs
(The American Society of Mechanical Engineers (ASME), 2016)Cylindrical compression springs have been commonly exploited in mechanical systems for years and their behavior is considered as well identified. Nevertheless, it appears that, even though old research studies suggest ... -
Designing and Harnessing the Metastable States of a Modular Metastructure for Programmable Mechanical Properties Adaptation
(The American Society of Mechanical Engineers (ASME), 2016)Recent studies on periodic metamaterial systems have shown that remarkable properties adaptivity and versatility are often the products of exploiting internal, coexisting metastable states. Motivated by this concept, this ... -
The Foldability of Cylindrical Foldable Structures Based on Rigid Origami
(The American Society of Mechanical Engineers (ASME), 2016)Foldable structures, a new kind of space structures developed in recent decades, can be deployed gradually to a working configuration and also can be folded for transportation, thus have potentially broad application ... -
A Compilation of Design for Environment Guidelines
(The American Society of Mechanical Engineers (ASME), 2016)Policymakers, consumers, and industry leaders are increasingly concerned about the environmental impacts of modern products. In response, product designers seek simple and effective methods for lowering the environmental ... -
Automatic Generation of Anisotropic Patterns of Geometric Features for Industrial Design
(The American Society of Mechanical Engineers (ASME), 2016)While modern computer aided design (CAD) systems currently offer tools for generating simple patterns, such as uniformly spaced rectangular or radial patterns, these tools are limited in several ways: (1) They cannot be ... -
Additive Manufacturing and Performance of Functional Hydraulic Pump Impellers in Fused Deposition Modeling Technology
(The American Society of Mechanical Engineers (ASME), 2016)Would it be possible for an additively manufactured impeller of fused deposition modeling (FDM) technology to have a functional behavior and a similar performance to that of the original impeller of a closecoupled centrifugal ... -
Optimization on Metamodeling Supported Iterative Decomposition
(The American Society of Mechanical Engineers (ASME), 2016)The recently developed metamodelbased decomposition strategy relies on quantifying the variable correlations of blackbox functions so that highdimensional problems are decomposed to smaller subproblems, before performing ... -
System Architecture, Level of Decomposition, and Structural Complexity: Analysis and Observations
