A Transformation Method to Generate the Workspace of an n(3RRS) Serial–Parallel Manipulator
(American Society of Mechanical Engineers (ASME), 2019)This paper presents a transformation method to generate the workspace of an n(3RRS) serial–parallel manipulator (S–PM). Firstly, the boundary of the workspace of the 3RRS parallel manipulator (PM) is obtained using the ... -
How We Solve the Weights in Our Surrogate Models Matters
(American Society of Mechanical Engineers (ASME), 2019)The construction of surrogate models, such as radial basis function (RBF) and Kriging-based surrogates, requires an invertible (square and full rank matrix) or pseudoinvertible (overdetermined) linear system to be solved. ... -
Singularity Avoidance for a Deployable Mechanism Using Elastic Joints
(American Society of Mechanical Engineers (ASME), 2019)This paper aims at dealing with the deployment vibration problem of the rigid-links deployable mechanism caused by mobility bifurcation. A triangular prismoid deployable mechanism with mobility bifurcation is employed as ... -
Wisdom of Microcrowds in Evaluating Solutions to Esoteric Engineering Problems
(American Society of Mechanical Engineers (ASME), 2019)A multitude of studies in economics, psychology, political and social sciences have demonstrated the wisdom of crowds (WoC) phenomenon, where the collective estimate of a group can be more accurate than estimates of ... -
Control of Process Settings for Large-Scale Additive Manufacturing With Sustainable Natural Composites
(American Society of Mechanical Engineers (ASME), 2019)We present a system for 3D printing large-scale objects using natural biocomposite materials, which comprises a precision extruder mounted on an industrial six-axis robot. This paper highlights work on controlling process ... -
Optimum Design of Serial Robots
(American Society of Mechanical Engineers (ASME), 2019)An optimum design of an industrial robot can be achieved from different point of views. For example, a robot can be conceived from the standpoint achieving maximum workspace or minimum weight, etc. In this paper, the ... -
Structural Synthesis of Baranov Trusses With Up to 13 Links
(American Society of Mechanical Engineers (ASME), 2019)The structural synthesis of Baranov trusses is still an open problem, although Baranov trusses are widely used in the design and analysis of mechanisms and robots. This paper proposes a systematic method for the structural ... -
A Hybrid Computational and Analytical Model of Inline Drip Emitters
(American Society of Mechanical Engineers (ASME), 2019)This paper details a hybrid computational and analytical model to predict the performance of inline pressure compensating drip irrigation emitters. Pressure compensating emitters deliver a constant flow rate over a range ... -
Does the Preferences for Creativity Scale Predict Engineering Students' Ability to Generate and Select Creative Design Alternatives?
(American Society of Mechanical Engineers (ASME), 2019)Creativity is universally acknowledged as an important attribute of successful engineering design, but individual attributes and preferences can influence whether creative ideas come to fruition during the design process. ... -
Is More Less? Benefits and Costs of High-Variety Production in Nonassembled Manufacturing
(American Society of Mechanical Engineers (ASME), 2019)While many studies have characterized the costs of product variety in assembly production, there is little research detailing the sources and costs of increased product variety on a nonassembled (fabrication) production ... -
Combined Level-Set-XFEM-Density Topology Optimization of Four-Dimensional Printed Structures Undergoing Large Deformation
(American Society of Mechanical Engineers (ASME), 2019)Advancement of additive manufacturing is driving a need for design tools that exploit the increasing fabrication freedom. Multimaterial, three-dimensional (3D) printing allows for the fabrication of components from multiple ... -
Experimental Investigation of the Implications of Model Granularity for Design Process Simulation
(American Society of Mechanical Engineers (ASME), 2019)Determining a suitable level of description, or granularity, for a product or process model is not straightforward, especially since granularity can manifest in multiple ways, but it is important to capture important ... -
Topology Optimization of Periodic Structures With Substructuring
(American Society of Mechanical Engineers (ASME), 2019)Topology optimization of macroperiodic structures is traditionally realized by imposing periodic constraints on the global structure, which needs to solve a fully linear system. Therefore, it usually requires a huge ... -
