Accelerated environmental degradation of GRP composite materials.
(2004)
The use of fibre reinforced polymer composites and development of structural composites has expanded rapidly in the Southern African region over the past ten years. The long-term effect of placing these materials outdoors ...
Condition monitoring of a rotor bearing system.
(2013-05-22)
The key objective for this research was to construct an experimental test rig along with a finite
element model. Both had to accommodate a certain extent of misalignment and unbalance to
provide induced vibrations in the ...
Numerical simulation of the structural response of a composite rocket nozzle during the ignition transient.
(2009)
The following dissertation describes an investigation of the structural response behaviour of a
composite solid rocket motor nozzle subjected to thermal and pressure loading during the motor
ignition period, derived on ...
Development of a hybrid sounding rocket motor.
(2013)
This work describes the development of a hybrid rocket propulsion system for a reusable sounding rocket,
as part of the first phase of the UKZN Phoenix Hybrid Sounding Rocket Programme. The programme
objective is to ...
The optimisation of train make-up and train handling-simulating longitudinal train dynamics.
(2000)
The South African rail industry is undergoing a phase of restructuring and much focus
is concentrated on re-engineering i.e. optimising the utilisation of available assets and
using existing technology in order to improve ...
Design and optimization of prototype trip steel smart aircraft bolt.
(2008)
Aviation is known to have some of the most stringent structural health monitoring standards in
the world. An example of this would be the fact that certain bolts in the aircraft assembly must
be periodically removed and ...
Modeling and experimental validation of a loop heat pipe for terrestrial thermal management applications.
(2013-10-31)
The Loop Heat Pipe (LHP) is a passive, two-phase heat transfer device used, most commonly,
for thermal management of aerospace and aeronautical electronic equipment. A unique feature
is a porous wick which generates the ...
The computational investigation of the wind-induced vibration of overhead conductors.
(2013)
The reliable transmission of high-voltage electricity through overhead electrical conductors is a cornerstone of the modern industrialised world. Any situation or phenomenon that impedes the functioning of this network ...
Development of a modular reconfigurable machine for reconfigurable manufacturing systems.
(2010)
The Reconfigurable Manufacturing Systems (RMSs) paradigm has been formulated to
encapsulate methodologies that enable manufacturing systems to effectively cope with changes in
markets and products. RMSs are systems which ...
Controlling chaos in a sagittal plane biped model using the Ott-Grebogi-Yorke method.
(2012)
Controlling a system with chaotic nature provides the ability to control and maintain orbits of different
periods which extends the functionality of the system to be flexible. A system with diverse dynamical
behaviours ...
