(University of Pretoria, 2013)The present work addresses the thermodynamic optimization of small binary-cycle geothermal power plants. The optimization process and entropy generation minimization analysis were performed to minimize the overall exergy ...
-
(University of Pretoria, 2009-06-29)The aim of this study is to investigate the use of multi-body vehicle simulation models to predict the suspension forces acting on the chassis of the vehicle, in order to perform durability analyses. Traditionally, durability ...
-
(University of Pretoria, 2012-05-21)An exponentially growing global population, power demands, pollution levels and, on the other hand, rapid advances in means of communication have made the public aware of the complex energy situation. The Kingdom of Saudi ...
-
(University of Pretoria, 2006-01-11)It is argued that together with improved protection structures and energy dissipation systems, a favourable pilot position with sufficient support and restraint could reduce fatalities in aviation accidents. In this document ...
-
(University of Pretoria, 2011)The purpose of this study was to develop a robust fluid-structure-interaction (FSI) technology that can accurately model non-linear flutter responses for sub- and transonic fluid flow. The Euler equation set governs the ...
-
(University of Pretoria, 2006-12-21)The casualty rate of road vehicle accidents in South Africa is one of the highest in the world. This trend has persisted with little variation over the years, despite the efforts of local road safety organisations and ...
-
(University of Pretoria, 2006-12-21)This study investigates the use of vibration and strain measurements on machine tools in order to identify the propagating wear of the selected tools. Two case studies are considered, one of which was conducted in the plant ...
-
(University of Pretoria, 1999)In this study, experimental tests and Computational Fluid Dynamics are used to investigate the aerodynamic performance of two types of track-based racing cars. After the literature study, where automotive aerodynamics is ...
-
(University of Pretoria, 2006-12-20)AFRIKAANS: 'n Basiese toets spesifikasie, vir die toets van bak-kappies van ligte kommersieële voertuie word voorgestel. Die toets spesifikasie is 'n eerste stap na die kwalifikasie van die sterkte van bakkie-kappies tydens ...

Methods for the determination of accessible workspaces of planar Stewart platforms of general design (University of Pretoria, 2006-12-20)In recent years Stewart platforms have been increasingly studied and developed. These parallel manipulators offer a number of advantages over traditional serial manipulators including high rigidity, good positioning accuracy ...
-
(University of Pretoria, 2006-12-20)High levels of vibration are essential for the proper operation of vibrating screens. However, this motion imparts high dynamic loads on their support structures leading to premature failure or costly construction. Various ...
-
(University of Pretoria, 2006)The implementation of finite element methods (FEM) for fatigue analysis of complex structures in industry are becoming an increasingly effective and accepted practice. In the case of large plate-like structures, such as ...
-
(University of Pretoria, 2005)Owing to the crippling nature of arthritis, surgeons have been trying for well over a century to successfully treat this debilitating disease particularly when attacking the hip joint. In the early 1970s, Sir John Charnley ...
-
(University of Pretoria, 2009)In recent years more emphasis has been placed on in-situ condition based monitoring of engineering systems and structures. Aerospace components are manufactured from composite materials more often. Structural health ...

(University of Pretoria, 2006-12-02)Please read the abstract in the section 00front of this document
-
(University of Pretoria, 2006-12-01)Parallel manipulators have many advantages over traditional serial manipulators. These advantages include high accuracy, high stiffness and high load-to-weight ratio, which make parallel manipulators ideal for machining ...

-
(University of Pretoria, 2009-12-09)An alarming number of compression ignition (CI) engines in the transport, mining and heavy engineering environments have been failing due to combustion irregularities within their combustion chambers. It has been found ...
-
(University of Pretoria, 2009-12-09)In the automotive industry one of the methods used in accelerating the design, testing and development of a system or a vehicle is the use of virtual vehicle simulations. The simulations cut costs in the form of fewer ...
-
(University of Pretoria, 2008)This thesis investigates the use of an active anti-roll bar as a means of improving the handling of an off-road vehicle. The active anti-roll bar consists of a stiff anti-roll bar and a hydraulic actuator at the one end ...
