Modes of vibration of inextensible cables suspended from two points

Creator:: Thompson, Roger S.
Abstract:: The equations of motion of a suspended, inextensible cable in the absence of damping are studied. A method is developed and illustrated for determining the frequencies and mode shapes for small oscillations about the equilibrium configuration. With the introduction of a new variable, the fourth order equation governing tangential displacement...

Experiments on cable strumming and flow induced drag

Creator:: Barnes, Bert Lee
Abstract:: Short non-flexible elements of cable were driven harmonically in water while constrained by springs. The cable elements were observed to oscillate at approximately the Strouhal vortex shedding frequency. Damped resonance occurred near the point where the natural frequency and the Strouhal vertex shedding frequency were equal. Transverse oscillation amplitudes greater...

Alternating current and voltage profiles on compensated high-voltage underground power cables

Creator:: Hirakami, Michael
Abstract:: The utilization of extra-high-voltage underground power cables over distances greater than 100 miles presents serious problems relative to the voltage and current limits of such cables. These problems are directly associated with the fixed amount of capacitance inherent in long cable lines. As a result, large charging currents are characteristic...

Theoretical and experimental investigations of FSK data transmission in the noise and interference environment of broadband two-way cable television systems

Creator:: Anderson, Harry R.
Abstract:: Two-way transmission of data on broadband community cable television systems is considered in this thesis. A discussion of the data transmission environment is presented which attempts to characterize the channel noise and interference which degrades data transmission performance. The analysis considers channel degradation resulting from additive gaussian noise and various...

Fiber Reinforced Composite Power-Mooring Cables Design and Manufacturing applied to Wave Energy Converters

Creator:: Miller, Andrew
Abstract:: The design and analysis of single point power-mooring cables applied to wave energy converters (WECs) is presented. WECs are mechanical devices designed and deployed to extract energy from waves in varying ways, and at varying distances from the shoreline. WEC devices operating on the water surface require mooring lines or...

Long cables under steady ocean loads with coupled tension/torsion

Creator:: Simpson, Randall C.
Abstract:: Cables used in the ocean are often constructed of helically wound wires or strands. Tension in the cable induces torque and/or rotation about its longitudinal axis. A method is presented to determine the tension, torque, location and angular orientation of points on the cable centerline, using a shooting method algorithm...

Active robust control of cable-stayed bridges

Creator:: Scheer, Dietmar
Abstract:: Long bridges tend to develop large deformations under the action of intense dynamical loads such as wind or earthquakes. Unless these deformations are controlled in some fashion, the structure might suffer damage or even collapse. One possible solution to this problem is to apply external forces to the bridge through...

Optimization and control of cable deployment systems

Creator:: Mtira, Mohamed
Abstract:: An optimization methodology, algorithms, and computer program for cable/lumped-body deployment system are developed for the design and installation of sonar packages in deep ocean ranges. In addition, a methodology and algorithms for the control of the system are proposed. A penalty function is developed in terms of the system parameters...

Finite Element Analysis Modeling and Experimental Verification of Reflected Wave Phenomena in Variable Speed Machine Drive Cables

Creator:: Louie, Alex
Abstract:: Modern variable speed machine drive (VSMD) systems are used for a variety of purposes including generation, propulsion, pumps and compressors. They employ high switching frequency power electronics to drive the electric machine. The machine is subject to large voltage overshoot if long power cables, are used, called Reflected Wave Phenomena...
