Spectral analysis for rod formation dynamics
(Virginia Tech, 1995)
This thesis deals with the production of a continuous rod of non-uniform properties which is formed by wrapping fibers with a thin membrane. This rod is driven axially and cut into segments. Measurements of pressure, ...
Modeling of multiple layered piezoelectric actuators in active structural control
(Virginia Tech, 1993)
The design and analysis of finite length, multiple layered, induced strain actuators is investigated. A model of an arbitrary multiple layered actuator is utilized to predict the applied force and moment from the i<sup>th</sup> ...
Development of a high-speed rotating bar mechanism
(Virginia Tech, 1995)
A high-speed rotary device was designed to generate shock waves in a transonic blowdown wind tunnel cascade. The rotary device (Rotating Bar Mechanism) will be used in research conducted at Virginia Tech to study the effects ...
A CADAM interface for the computer-aided selection of Timken tapered roller bearings
(Virginia Polytechnic Institute and State University, 1987)
This thesis presents an interactive computer-graphics geometry interface that simplifies the tapered roller bearing selection procedure. An applications program has been developed that links the CADAM data base to ...
A study of transient heat conduction and thermal noise in an Earth radiation budget radiometer
(Virginia Tech, 1996)
The suite of three Clouds and Earth’s Radiative Energy System (CERES) radiometers measure the radiation reflected from and emitted by the Earth from Earth orbit. The instruments are based on a two-mirror reflecting telescope ...
Noise due to pressure pulsations in a pressure-balanced sliding vane pump
(Virginia Polytechnic Institute and State University, 1987)
An experimental investigation of noise in a pressure-balanced sliding vane pump was conducted. The test pump for this research was used in an automobile's hydraulic power steering system. As currently designed, a small ...
The effects of ambient temperature variations on structural dynamic characteristics
(Virginia Tech, 1995)
The precise and detailed characterization of the dynamic response of structures has become increasingly important in recent years. As a consequence, the accuracy of experimental data, which is often used to validate and ...
An experimental examination of the effect of trailing edge thickness on the aerodynamic performance of gas turbine blades
(Virginia Polytechnic Institute and State University, 1989)
This thesis documents the experimental research conducted on a transonic turbine cascade. The cascade was a two-dimensional model of a jet-engine turbine with an, approximately, 1.2 design, exit Mach number, and was tested ...
Evaluation of the effects caused by a variation of parameters in a new process for the production of microporous polyethylene
(Virginia Polytechnic Institute and State University, 1988)
The effects caused by a variation of the key parameters involved in a proprietary process for the production of microporous polyethylene were investigated. The process involved the treating of a polyethylene film with two ...
Data acquisition systems for three-dimensional representation and analysis of surface topography and surface temperatures in tribological processes
(Virginia Polytechnic Institute and State University, 1986)
Data acquisition systems were developed for three-dimensional representation and analysis of surface topography and surface temperatures in tribological processes. 3-D information about the topography of surfaces was ...
