This paper investigates the nonlinear response of microelectromechanical system (MEMS) cantilever resonator electrostatically actuated by applying a soft alternating current (AC) voltage and an even softer direct current (DC) voltage between the resonators and a parallel fixed ground plate. The AC frequency is near natural frequency. This drives the resonator into nonlinear parametric resonance. The method ofmultiple scales (MMS) is used to solve the dimensionless differential equation of motion of the resonator and find the steady-state solutions.The reduced order model (ROM) method is used to validate the results obtained using MMS. The effect of the soft DC voltage (bias) component …
Unidirectional Rotary Tendency Of A Wave-Driven Rotor, Yingchen Yang
Unidirectional Rotary Tendency Of A Wave-Driven Rotor, Yingchen Yang
Mechanical Engineering Faculty Publications
Ocean waves can directly drive WECs (wave energy converters) to perform two types of motion—reciprocating motion and unidirectional rotary motion. In general, the efficiency of a reciprocating WEC is strongly wave-frequency dependent, whereas the efficiency of a rotary WEC can be somewhat wave-frequency independent. To date, a huge majority of WEC technologies under development in industry belong to the reciprocating class, and only a few WEC concepts fall in the unidirectional rotary class. In the present work, a wave-driven rotor for unidirectional rotary motion was proposed and characterized. A numerical tool has been developed for characterization of the rotor’s unidirectional …

Design And Optimization Of A Railroad Conductive Suspension Element Pad Composed Of Thermoplastic Polyurethane And Carbon Black, Ruben Suarez Jr.
Design And Optimization Of A Railroad Conductive Suspension Element Pad Composed Of Thermoplastic Polyurethane And Carbon Black, Ruben Suarez Jr.
Theses and Dissertations - UTB/UTPA
The AdapterPlus™ Pad, made from thermoplastic polyurethane (TPU), is used to enhance steering and prevent metal-to-metal contact between the railcar side frame and the bearing adapter. Although the AdapterPlus™ Pad acts as a pedestal liner in the suspension assembly, it must allow electric current to flow from the rail, through the bearing adapter wall to the side frame in order to activate a solenoid air valve that releases cargo gates. Currently, the pad uses copper inserts that allow current through. Because the Adapter Plus™ Pad is subject to large dynamic loads, the copper inserts permanently deform losing contact and cutting …
Nonlinear Dynamics Of Carbon Nanotubes Under Soft Alternating Current Actuation, Le Luo
Nonlinear Dynamics Of Carbon Nanotubes Under Soft Alternating Current Actuation, Le Luo
Theses and Dissertations - UTB/UTPA

Control Charts For First Order Autoregressive Analysis With An Exogenous Variable, Becky M. Vela
Theses and Dissertations - UTB/UTPA
There are many instances in industry, where the necessity of prediction models is extremely important. However, the difficulty of forecasting increases with the number of variables involved, and determining independent variables from dependent variables. Autocorrelation is one of the most common causes for many control charts and other quality measurement tools to falsely signal an error in the process. Time series models, such as autoregressive models, accommodate autocorrelated data to a certain extent. However, using a model that only analyzes historical data alone does not possess the accuracy necessary to be able to forecast data precisely. An addition of an …

Mechanical Engineering Faculty Publications
The addition of autonomic healing (frequently defined as self-healing) capabilities to a water-soluble polymer (polyethylene oxide, PEO) is for the first time reported. The self-healing system consists of urea-formaldehyde microcapsules filled with dicyclopentadiene and first-generation Grubbs catalyst, dispersed within polyethylene oxide. Raman spectroscopy, optical microscopy, electron microscopy, and thermogravimetric analysis were used to characterize this autonomic healing system. Self-healing capabilities were confirmed by mechanical testing (load–displacement, engineering stress–engineering strain, and true stress–true strain dependences) recorded at very slow elongation rates (0.01 mm/s). The testing fate was chosen to allow for the complete consumption of the monomer before fracture (the polymerization …
