-
(Southern African Institute for Industrial Engineering, 2000)Increased competitiveness in the production world necessitates improved maintenance strategies to increase availabilities and drive down cost . The maintenance engineer is thus faced with the need to make more intelligent ...
-
(Inderscience, 2007)The mathematical modelling of a suspension unit is considered. The unit comprises a hydraulic cylinder connecting the vehicle body to the unsprung mass, two nitrogen-filled accumulator springs and two damper ports. The ...
-
(Elsevier, 2007-04)This paper reports on an investigation to determine the spring and damper settings that will ensure optimal ride comfort of an off-road vehicle, on different road profiles and at different speeds. These settings are required ...
-
(Oxford University Press, 2007-04)OBJECTIVES: To compare the noise and vibration levels associated with three hand-held rock drills (pneumatic, hydraulic and electric) currently used in South African mines, and a prototype acoustically shielded self-propelled ...
-
(Elsevier, 2007-10)Retrievals obtained after revision surgery, provide valuable information on the rate of wear and the causes of wear that take place in vivo. The aim of this study was to perform a root cause failure analysis to determine ...
-
(Elsevier, 2007-10)When designing vehicle suspension systems, it is well-known that spring and damper characteristics required for good handling on a vehicle are not the same as those required for good ride comfort. Any choice of spring and ...
-
(Blackwell, 2007-11)This study entails the fatigue analysis of a complex plate-like structure subjected to random loading. The stress and fatigue life assessment is performed by means of experimental strain gauge measurements, finite element ...
-
(Maney, 2008)Twelve per cent chrome ferritic (non-stabilised) stainless steel cast at the continuous caster at Columbus Stainless exhibited notable differences in the width change between consecutive heats. The reason for these differences ...
-
(Sage, 2008)Besides reducing the restricting effects of tool vibrations on productivity, work-piece surface finish and tool life, it is desirable to handle lack of space for sensors at the tool tip and the cost of control systems in ...
-
(Hindawi, 2008)A novel dynamic interacting particle swarm (DYN-PSO) is proposed. The algorithm can be considered to be the synthesis of two established trajectory methods for unconstrained minimization. In the new method, the minimization ...
-
(Southern African Institute of Mining and Metallurgy, 2008-06)No abstract available
-
(IEEE, 2008-11)In this paper, heat extractors are embedded into the magnetic materials of the integrated power electronics passive modules. The optimum volume of heat-extracting material may slightly reduce the amount of electromagnetic ...
-
(Elsevier, 2009)This paper presents a signal analysis method used for condensing refrigerants that results in a modification in the prediction method for heat transfer based on probabilistic time-fractional results. Development of an ...
-
(Elsevier, 2009)It is common practice in the automotive industry to employ multi-parameter strain-life methods, in combination with dynamic finite element analyses, based on very extensive measurement exercises, to conduct analytical ...
-
(Asian Network for Scientific Information, 2009)This study presents the development of mathematical models for torque in end-milling of AISI 618. Response Surface Method (RSM) was used to predict the effect of torque in the end-milling. The relationship between the ...
-
(Massachusetts Institute of Technology Press, 2009)Two variants of the extended Rosenbrock function are analyzed in order to find the stationary points. The first variant is shown to possess a single stationary point, the global minimum. The second variant has numerous ...
-
(Asian Network for Scientific Information, 2009)This study discusses the development of a method for compensating profile errors, resulting from the deviation of the actual grinding wheel radius from the calculated one. The study also elaborates on a control strategy ...
-
(Elsevier, 2009)This paper presents an improved flow pattern map for predicting the heat transfer coefficients during condensation of R-134a inside a smooth horizontal tube. Experimental tests were conducted over the low-mass flux range ...
-
(Euro Journals, 2009)This paper explores on the optimization of the surface roughness of milling mould 6061-T6 aluminium alloys with carbide coated inserts. Optimization of the milling is very important to reduce the cost and time for machining ...
-
(Southern African Institute of Mining and Metallurgy, 2009-02)Rock bolt integrity is a critical issue for the mining industry because of its influence on the safety of mining operations. Guided ultrasonic wave testing of the defects associated with resinanchored rock bolts was ...
