A method for the spatial dynamic simulation of reciprocating compressors using the digital computer
(Virginia Polytechnic Institute and State University, 1987)
This thesis introduces the application of computer-aided engineering techniques to the dynamic analysis of reciprocating compressor designs. The analysis process is detailed in three steps.
The first step, an interactive ...
Design of a microcomputer-based open heart surgery patient monitor
(Virginia Polytechnic Institute and State University, 1985)
A patient monitor device for use during open heart surgery has been designed and constructed. The device uses a VIC 20 microcomputer along with some additional circuitry to monitor 3 separate functions. The first patient ...
DACS: an interactive computer program to aid in the design and analysis of linear control systems
(Virginia Polytechnic Institute and State University, 1985)
DACS is an interactive computer program for the IBM-PC that aids in the design and analysis of linear control systems. Written in compiled basic, DACS includes Root Locus, Bode plots, Nyquist diagrams, Nichols charts, ...
Dynamic simulation of solar calibration of the total, Earth- viewing channel of the Earth Radiation Budget Experiment (ERBE)
(Virginia Polytechnic Institute and State University, 1987)
The Earth Radiation Budget Experiment (ERBE) is an operational system of radiometric instruments placed in Earth orbit by the National Aeronautics and Space Administration (NASA). Its purpose is to monitor those components ...
Stored waveform adaptive motor control
(Virginia Tech, 1986-03-05)
This study investigates an adaptive control scheme designed to maintain accurate motor speed control in spite of high-frequency periodic variations in load torque, load inertia, and motor parameters. The
controller adapts, ...
A study of tip-leakage flow through orifice investigations
(Virginia Tech, 1987-10-05)
"Compressible fluid dynamics of flow through plain-faced long orifices was investigated with the hope of gaining insight into the fluid dynamics of tip leakage flow. The Reynolds number range investigated was greater than ...
Structural shape optimization of three dimensional finite element models
(Virginia Tech, 1987-08-26)
<p>The thesis presents a three dimensional shape optimization program which analyzes
models made up of linear isoparametric elements. The goal of the program is to achieve
a near uniform model stress state and thereby ...
Analytical method for turbine blade temperature mapping to estimate a pyrometer input signal
(Virginia Tech, 1987-05-05)
<p>The purpose of this thesis is to develop a method to estimate local blade
temperatures in a gas turbine for comparison with the output signal of an experimental
pyrometer. The goal of the method is to provide a ...
Development of a data reduction method for a high frequency angle probe
(Virginia Tech, 1987-03-15)
<p>A data reduction method has been developed and tested for a high frequency angle
probe. The angle probe is designed for unsteady aerodynamic measurements in
transonic cryogenic wind tunnels. The probe measures ...
A personal computer based instrumentation system for determining real-time dynamic torque in rotating machinery
(Virginia Tech, 1987-06-10)
<p>Measurement of dynamic/transient torques is important in the dynamic analysis of rotating
machinery as it provides insight into the internal state of the machine. Existing methods are
difficult to implement, results ...
