Toward Automatic Tolerancing of Mechanical Assemblies: First Order GD&T Schema Development and Tolerance Allocation
(The American Society of Mechanical Engineers (ASME), 2015)Geometric and dimensional tolerances must be determined not only to ensure proper achievement of design function but also for manufacturability and assemblability of mechanical assemblies. We are investigating the degree ... -
Rigidity Analysis of Protein Molecules
(The American Society of Mechanical Engineers (ASME), 2015)Intrinsic flexibility of protein molecules enables them to change their 3D structure and perform their specific task. Therefore, identifying rigid regions and consequently flexible regions of proteins has a significant ... -
Graph Based Method and Tool for Complete and Selective Disassembly Time Estimation in Early Design
(The American Society of Mechanical Engineers (ASME), 2015)The goal of this research is to develop a method and tool (a) to estimate disassembly time automatically from early embodiment design based CAD model and (b) to provide design suggestions to improve product disassemblability. ... -
Experimental Study of an Airplane Accident Evacuation/Rescue Simulation Using Three Dimensional Kinematic Digital Human Models
(The American Society of Mechanical Engineers (ASME), 2015)The 3D mass evacuation simulation of an airplane accident is experimentally verified. Evacuee motion has been experimentally investigated by building a test field that emulates the interior of an actual regional airliner ... -
Problem Map: An Ontological Framework for a Computational Study of Problem Formulation in Engineering Design
(The American Society of Mechanical Engineers (ASME), 2015)Studies of design cognition often face two challenges. One is a lack of formal cognitive models of design processes that have the appropriate granularity: fine enough to distinguish differences among individuals and coarse ... -
Task Oriented Adaptive Maintenance Support System
(The American Society of Mechanical Engineers (ASME), 2015)Technical manuals for complex systems like automobiles, airplanes, and machine tools, often consist of a huge amount of documentation containing disassembling, assembling instructions and drawings of parts, subassemblies, ... -
A Publishing Method of Lightweight Three Dimensional Assembly Instruction for Complex Products
(The American Society of Mechanical Engineers (ASME), 2015)In order to accurately guide onsite workers to quickly accomplish the assembly job of complex products, and reduce the deployment cost of assembly instruction, we propose a publishing method of lightweight 3D assembly ... -
Comparison of Skin Model Representations and Tooth Contact Analysis Techniques for Gear Tolerance Analysis
(The American Society of Mechanical Engineers (ASME), 2015)To improve the tolerancing process in an industrial context, there exists a strong need for tolerance analysis to estimate the probability of scrap in an acceptable computer time and managing the accuracy of the results. ... -
Competitive Usability Analysis of Immersive Virtual Environments in Engineering Design Review
(The American Society of Mechanical Engineers (ASME), 2015)A competitive usability study was employed to measure user performance and user preference for immersive virtual environments (VEs) with multimodal gestural interfaces when compared directly with nonstereoscopic traditional ... -
Integrated, Synchronous Multi User Design and Analysis
(The American Society of Mechanical Engineers (ASME), 2015)An integrated multiuser system for synchronous design and analysis improves collaboration and concurrent engineering across multiple engineering disciplines. This approach allows all members of a multidisciplinary team ... -
Quantifying Product Favorability and Extracting Notable Product Features Using Large Scale Social Media Data
(The American Society of Mechanical Engineers (ASME), 2015)Some of the challenges that designers face in getting broad external input from customers during and after product launch include geographic limitations and the need for physical interaction with the design artifact(s). ... -
Manufacturing Signature for Tolerance Analysis
(The American Society of Mechanical Engineers (ASME), 2015)Every manufacturing process leaves on the surface a signature, i.e., a systematic pattern that characterizes all the features machined with that process. The present work investigates the effects of considering the ... -
Geometrical Simulation of Multiscale Toleranced Surface With Consideration of the Tolerancing Principle
(The American Society of Mechanical Engineers (ASME), 2015)Surface quality and accuracy are the most important factors that affect the performance and life cycle of products. Surface deviations are confirmed to be nonstationary random signals. They show characteristics of randomness, ... -
Comparison of Analysis Line and Polytopes Methods to Determine the Result of a Tolerance Chain
(The American Society of Mechanical Engineers (ASME), 2015)Functional tolerancing must ensure the assembly and the functioning of a mechanism. This paper compares two methods of tolerance analysis of a mechanical system: the method of “analysis lines†and the method of ... -
Numerical Analysis of the Feldkamp–Davis–Kress Effect on Industrial X Ray Computed Tomography for Dimensional Metrology
(The American Society of Mechanical Engineers (ASME), 2015)Xray computed tomography (CT) can nondestructively inspect an object and can clearly, accurately, and intuitively display its internal structure, composition, texture, and damage. In industry this technology was initially ... -
Contact and Mobility Simulation for Mechanical Assemblies Based on Skin Model Shapes
(The American Society of Mechanical Engineers (ASME), 2015)Assembly modeling as one of the most important steps in the product development activity relies more and more on the extensive use of computeraided design (cad) systems. The modeling of geometric interfaces between the ... -
Welding Simulation of Non Nominal Structures With Clamps
(The American Society of Mechanical Engineers (ASME), 2015)In any industrial assembly process, there are a number of sources of variation. Variation in the manufacturing process leads to component variation, which, together with fixture variation and variation stemming from the ... -
