Wind Powered Robots – AME Pre-Capstone Project

The Mechanical Engineering Pre-Capstone project revolves around a central semester-long, team-based project. This project is designed to provide students with the opportunity to act as junior engineers exploring solutions to a complex, multi-level, and competency-building problem. This experiential learning provides the basis on which competencies will be further developed for students entering their Capstone project.

This year’s task is to design, build and test a system capable of converting wind energy into some more useful form of energy and then store this energy in some compact, transportable module. The wind source will be represented by a household electric fan, and the energy modules must be used to propel a vehicle, carrying large payload around a track.

Students are actively at work this semester and eager to complete the task at hand!

Mechanical Engineer senior, Adam Kordsiemon, gives us an insight to his groups journey at tackling this year’s Pre-Capstone project.

Gaylord student produces video of Dr. Chung-Hao Lee’s Research.

Gaylord student Victor Pozadas filmed and created a video on Dr. Chung-Hao Lee’s research. The video encompasses the work that Lee has been conducting with students in his lab. His research focuses on cardiovascular biomedical modeling and working with biological tissues and patient-specific modeling for improved diagnosis.

The goal of this current project is to take a patient specific geometry and put it into this model to figure out what treatment would work best for the patient. They are able to show how therapeutics effect the mechanics. The students said that it is really amazing to be able to work on a heart since mechanical engineers typically work with steel.

Thank you to Victor Pozadas for filming Dr. Lee’s work for others to see.

Researchers Mistree and Allen Publish New Research Findings

AME and ISE researchers Farrokh Mistree and Janet K. Allen released a monograph containing a fail-safe supply network that is designed to mitigate the impact of variations and disruptions on people and corporations. Mistree and Allen co-direct the Systems Realizations Laboratory at OU, which focuses on collaborative research in intelligent decision-based realizations of complex social systems. Ultimately, this work is aimed at educating strategic engineers.

In this monograph, they propose a framework, develop mathematical models and provide examples of a fail-safe supply network design. This is achieved by developing a network structure to mitigate the impact of disruptions that distort the network structure and planning flow through the network to neutralize the effects of variations.

The researchers asses current thinking at different levels of management within a network. The strategy revolves around 5 elements: reliability, robustness, flexibility, structural controllability, and resilience. Organizations can use the framework presented in this monograph to manage variations and disruptions. Managers can select the best operational management strategies for their supply networks considering variations in supply and demand and identify the best network restoration strategies. The framework is generalizable to other complex engineered networks.

The monograph was published October 15th, 2018 and is available for purchase here:

Russell W. Mailen Ph.D. presents over Thermo-Mechanical Behavior of Light Stimulated Shape Memory Polymer Sheets

This past Friday, AME had the honor of observing a presentation from Auburn professor Russell W. Mailen Ph.D. Mailen is an Assistant Professor in the Department of Aerospace engineering at Auburn University. His research focuses on the time-dependent properties of polymers, polymer composites, and computational modeling of shape memory polymers.

His presentation was over Thermo-Mechanical Behavior of Light Stimulated Shape Memory Polymer Sheets. In general, he is researching self-folding systems that use heat to cause motion. His research objectives include:

  • Formulating and implementing a coupled thermo-mechanical model into a 3D nonlinear finite element framework
  • Model material recovery in response to heat. (Validate model through uniform shrinkage and Demonstrate hinged folding which is critical for self-folding origami)

 

  • Generalize model for different coupled thermal and mechanical loading conditions to obtain optimized origami structures (Optimize structures by control of thermos-mechanical response to external stimuli)

 

Thanks to Professor Yingtao Liu who reached out to Mailen to come to OU and thanks to him for an interesting and dynamic presentation!

If you are interested in more information on his research, here is his abstract:

Shape memory polymers (SMPs) represent a class of active materials that can change shape in response to external stimuli such as heat, light, and solvents. Although SMPs have many applications, we are primarily interested in using the material as environmentally responsive actuators for self-folding origami structures. Previously, we developed a method to activate SMPs using light. Ink patterned on the polymer surface absorbs thermal energy from an infrared (IR) light which results in localized heating and shrinking of the sheet. The shrinking behavior can be harnessed to produce folded and curved structures. We investigate the thermo-mechanical response of this system by developing a three-dimensional (3D), non-linear finite element model. This model accounts for external heat sources, such as the IR light, as well as internal heat generation caused by dissipation of viscous energy. The model shows how the coupled thermo-mechanical loading conditions affect folding and unfolding of SMP sheets in response to localized heating in ink patterned regions. We conduct a parametric study of sheet thickness, hinge width, degree of pre-strain, and hinge surface temperature, and we demonstrate methods for generating 3D, curved structures. Self-folding can be used to obtain 3D structures from planar sheets for an array of applications, including medical stents, antennas, and engineered, origami applications, such as space telescopes.

Dr. Chung-Hao Lee and Dr. Yingtao Liu receive $45,000 award from Center for the Advancement of Science and Technology

Dr. Chung-Hao Lee and Dr. Yingtao Liu have received an award from the Center for the Advancement of Science and Technology. It is a $45,000 award from the State of Oklahoma for the research project titled “(HR) Novel Shape Memory Polymer Devices for Optimal Endovascular Embolization of Intracranial Aneurysms.”

The collaborative team for this interdisciplinary research has been established among bioengineer Dr. Chung-Hao Lee, material scientist Dr. Yingtao Liu, and neurosurgeon Dr. Bradley Bohnstedt (OUHSC), as well as student researchers in various engineering disciplines of the Gallogly College of Engineering. This project is currently supported by the 2017 Gallogly SEED Funding for Interdisciplinary Research, Faculty Investment Program (FIP) sponsored by the Office of the Vice President for Research, and the Pilot Research Program from the Oklahoma Shared Clinical and Translational Resources (OSCTR).

The project is the development of a novel medical device for surgical treatment of intracranial aneurysms. Incidental rupture of an intracranial aneurysm results in subarachnoid hemorrhage (SAH), which causes about 10% of an individual’s death before reaching medical attention. The overall objective of this research project is to identify objective hemodynamic and biomechanical criteria derived from predictive computer simulations for designing embolic devices and to develop the prototypes of embolic devices using aliphatic urethane shape memory polymers (SMPs), which possess excellent shape memory property, as a novel therapeutic technique for patient-specific endovascular embolization of intracranial aneurysms. The developed SMP foam-based embolic devices are expected to achieve short preparation time, optimal complete occlusion, and a significantly reduced rate of aneurysm recurrence. The development of such innovative technologies is expected to be beneficial to the healthcare of Americans with a stroke history and will dramatically reduce the corresponding in-hospital expenditure.
