Experimental Building Demonstration Model With Viscous Fluid Dampers, Blake Thomas Reeve, Brianna Jean Kufa, Aden Malek Stepanians, Sophie Carmion Ratkovich

Architectural Engineering

The Architectural Engineering major places a heavy emphasis on structural dynamics and the role of wind and seismic loading in building analysis and design. Buildings of high importance that are critical to community function, such as hospitals, often utilize supplemental damping devices like supplemental viscous fluid dampers or base isolators to reduce the overall demands on the structural system. The design and analysis of these dampers are typically not taught at the undergraduate level, and is frequently performed by mechanical engineers, in lieu of structural engineers.

To better understand and research building behavior with supplemental damping devices, our multi-disciplinary team ...

Mechanical Engineering

A lectern is an essential piece of equipment for almost all speeches and presentations. They come in many forms and range in degree of professionalism depending on the occasion. Lecterns not only hold a presenter’s notes, a microphone, or other presentation aids, they provide a structure for a presenter that can bolster their confidence during a presentation. As such, it is important that all presenters have a lectern available to them. Unfortunately this is not always the case due to lectern accessibility limitations. This problem inspired the Cal Poly Disability Resource Center to request a lectern that satisfies the ...

The rig provides a steady state measurement of the ESC heat output by passing a known mass flow rate of air across the ESC and measuring the temperature difference. It uses a flowmeter to determine ṁ, thermocouples to determine ΔT, and a table lookup to ...


Compliant Air Skates, An Experiment, Samuel Feldtkeller, Cody Anderson, Kevin Daily, Eliana Stefani 2016 California Polytechnic State University, San Luis Obispo

Compliant Air Skates, An Experiment, Samuel Feldtkeller, Cody Anderson, Kevin Daily, Eliana Stefani

Mechanical Engineering

There is currently a gap in the market of train levitation systems: wheeled trains and MagLev trains exist, but none utilize the low friction and high efficiency aspect of trains levitated by air skates. An air skate, is an air bearing that uses a pressure difference along its annular body to create a thin flow of air which is strong enough to "levitate" the weight of the skate. We have designed a compliant air skate that can glide over 0.04[in] defects in surfaces without touching down. After having made compliant skirts out of fiberglass and silicone, our setup ...

The challenge of providing large amounts of electrical energy for spacecraft over the course of long du-ration missions has long been an area of aerospace research. This need is particularly pronounced for a solar-powered in-space 3D printer [1]. Solar flux is commonly collected with solar panels for powering spacecraft. This is a reliable and safe method for electricity generation. Other generation methods, such as onboard nuclear power, present safety concerns.
Large solar collectors also have other benefits over alternate electricity generation methods. Theses benefits include using the solar collector as a solar shade, and using the back side of the ...

Jeremy Straub

The purpose of this poster is to explore space based power generation capabilities and transmission based on using Origami Style Solar and Antenna Panels (OSSAP). Basically, the OSSAP is designed to be a new type of origami panels that operate differently from conventional solar panels and antennas. They should be easier to manufacture and usable on a wide range of spacecraft. They have a lower launch volume and mass; however, once in space the system unfolds to provide a large surface area. The unfolding can be done in several ways including using a pressurized gas system for deployment. This method ...

In-Space 3d Printing Scientific Remote Sensing Missions, Michael Hirsch, Thomas Mcguire, Skye Leake, Michael Parsons, Jeremy Straub, Scott Kerlin

Jeremy Straub

Currently, remote sensing missions involve the pro-duction of complex and deployable structures that must withstand the forces involved with launching and assembly in space. To combat this, the technology of 3D printing [1] can be applied. Additive manufacturing technology has improved greatly in the recent past, al-lowing for the possibility of in-space 3D printing [2].
By taking the concepts of 3D printing and using them for scientific remote sensing missions [3], it is possible to print structures that would be otherwise impossible, due to constraints for terrestrial construc-tion, launch and deployment. A design is proposed in [2] that will both ...

Design For An In-Space 3d Printer, Thomas McGuire, Michael Hirsch, Michael Parsons, Skye Leake, Jeremy Straub, Scott Kerlin 2016 Selected Works

Design For An In-Space 3d Printer, Thomas Mcguire, Michael Hirsch, Michael Parsons, Skye Leake, Jeremy Straub, Scott Kerlin

Jeremy Straub

Getting into space is a key constraint of current space mission designs. Launching spacecraft or components for spacecraft into space requires large amounts of structural components and packaging to secure it, adding additional mass and cost to the launch. Being able to bypass this current system would allow more frequent and cheaper space missions. An in space 3D printer is key to this. By placing a 3D printer in orbit, raw material (which requires less support and packaging to ship) can be sent to space. Craft and components can be fabricated on demand. This also allows craft to be designed ...
