  • Wind turbulence input model for horizontal axis wind turbines

    Creator:
    Lin, Shuh-ren
    Abstract:
    In order to estimate wind turbine residL2;characteristics in the presence of atmospheric turbulence, the important atmospheric sources for the force excitations felt by the wind turbine system must be identified and characterized. The goal of this research is to develop the wind turbulence input model for horizontal axis wind turbines....

  • Mechanics of Nb-Ti superconducting composites

    Creator:
    Guo, Zhiqiang
    Abstract:
    Mechanical behavior of Nb-Ti superconducting composites with copper matrices have been studied experimentally and theoretically. Experimental work includes extensive measurements of Cu/Nb-Ti composite system. Techniques for fine fiber testing and composite wire measurement have been developed. Experimental parameters examined in this research include geometry, hardness, Young's modulus, Poisson's ratio, yield...

  • Vehicle dynamic validation and analysis from suspension forces

    Creator:
    Murray, William S.
    Abstract:
    Several standardized courses for Formula SAE (FSAE) testing are introduced and described with sufficient detail to be reproduced by any Formula SAE team. Basic analysis methods for the courses are given as well as explanations of how those analyses could be used. On-car data from the Global Formula Racing (GFR)...

  • A study of compression loading of composite laminates

    Creator:
    Berbinau, Pierre J.
    Abstract:
    The compressive behavior of continuous fiber composites is not as well understood as their tensile behavior because research and industrial applications have until recently focused on the latter. Furthermore, most theoretical and experimental studies on the compression of composites have examined the case of unidirectional specimens with fibers along the...

  • Large-strain softening of aluminum in shear at elevated temperature

    Creator:
    Alhajeri, Saleh N.
    Abstract:
    Pure aluminum deformed in torsion (shear) at elevated temperatures reaches a broad "peak" stress and then undergoes about a 17% decrease in flow stress with deformation to roughly 1-2 equivalent uniaxial strain. Beyond this strain the flow stress is approximately constant. The sources for this softening are unclear. The suggested...

  • Processing of laser interferometric signals for small displacement measurements

    Creator:
    Peng, Gwo-sheng
    Abstract:
    Algorithms for analyzing laser interferometry signals were developed and adopted to the computer based processing of small displacement measurements. These methods, matrix operation approach and fixed parameters approach, are based on signal phase calculation and are able to replace complex fringe counting electronic circuits. The matrix operation provides an approach...

  • Drilling process evaluation by predicting drilled hole quality and drill bit wear with on-line acoustic emission signals

    Creator:
    Wang, Kuang-Jen, 1962-
    Abstract:
    Improvement of manufacturing productivity is dependent on the successful automation of manufacturing processes, the success of which is based in turn upon the availability of information which describes the state of manufacturing operations. Acoustic Emission (AE) signals related to the cutting process and tool wear have been recently applied to...

  • Robust controller design for robotic manipulators with saturation

    Creator:
    Liang, Zuyang
    Abstract:
    The development of modern industries calls for the robotic manipulators with high speed and accurate tracking performance. Many authors have paid attention to robust control of robotic manipulators; however, only few authors have also considered the control problem of manipulators with power limitation. In this dissertation, the robotic manipulator is...

  • The application of a band variable-inertia flywheel to an urban transit bus

    Creator:
    Moosavi-Rad, Hamid
    Abstract:
    This dissertation investigates by means of computer simulation the potential of a Band Variable-Inertia Flywheel (BVIF) to store energy for an urban transit bus. Replacing both a fixed-inertia flywheel (FIF) and a continuously variable transmission (CVT), the Band Variable-Inertia Flywheel is capable of accelerating a vehicle from rest to a...
