Effect Of Process Parameters On The Surface Roughness And Mechanical Performance Of Additively Manufactured Alloy 718, Bo Ryan Whip Jan 2018

Effect Of Process Parameters On The Surface Roughness And Mechanical Performance Of Additively Manufactured Alloy 718, Bo Ryan Whip

Browse all Theses and Dissertations

Metal additive manufacturing (AM) is a method to create complex components in a layer-by-layer process. Currently, there is a lack of understanding in the processing-structure-properties-performance relationship, particularly related to defects inherent to the AM process. This work investigates the relationship of process parameters, as-built surface roughness, and mechanical performance for nickel-based superalloy 718 built using laser powder bed fusion. The surface roughness of components built using varied processing parameters was characterized using both nondestructive and destructive measurement techniques. Finite element analysis was used to study the stress concentration on surface profiles. Statistical correlations are presented between contour processing parameters and …


High Accessibility Cabinet Insert, Matthew Leal Jan 2017

High Accessibility Cabinet Insert, Matthew Leal

All Undergraduate Projects

Watching grandparents and parents get older, the struggle of day-to-day activities generally increases. One of the most recurring issues the older generation experiences nearly daily is their inability to reach dishes, glassware, and other things on the topmost shelves of a kitchen. Not only is it difficult for them to use things such as stepstools, it also becomes increasingly dangerous. With age, a fall from any height could be catastrophic. With this scenario in mind, a user-friendly cabinet insert would be a very effective way to combat this issue. However, many existing models of cabinet designed to fit these requirements …


Investigation Of Extremum Seeking Control For Adaptive Exercise Machines, Brahm T. Powell Jan 2017

Investigation Of Extremum Seeking Control For Adaptive Exercise Machines, Brahm T. Powell

ETD Archive

Many muscle rehabilitation regimens are non-adaptive and recommended subjectively by physicians. While there are advantages to having the feedback of a qualified physician, utilizing real-time muscle performance feedback could be beneficial. An extremum seeking control design is proposed to fulfill the need for an automated, load-varying exercise machine that can optimize muscle performance.

Several steps are outlined to contribute to the realization of this goal. First, the extremum seeking control scheme is discussed. Second, the Hill muscle model will be described. Theoretical muscle effort extrema will be derived for selected optimization cases, namely maximizing average squared power by varying load …


Design And Control Of A Powered Rowing Machine With Programmable Impedance, Jose Humberto De La Casas Zolezzi Jan 2017

Design And Control Of A Powered Rowing Machine With Programmable Impedance, Jose Humberto De La Casas Zolezzi

ETD Archive

Due to the rise of obesity, diabetes and cardiovascular disease, research in human performance and physical activity has received increased attention. Rowing machines are used for performance improvements through concentric exercises, however a combination of concentric and eccentric actions is known to improve the effectiveness of training. In this work, a conventional rowing machine was modified to include an electric motor and a robust impedance control system, enabling programmable impedance with concentric and eccentric capabilities. Eccentric exercises are known to contribute significantly to the efficacy of training and to diminish the detrimental effects of humans operating in microgravity for long …
