The use of scale models for investigating the dynamic behaviour of rope-guide mine shaft installationsVan der Elst, Willem Jacob January 1965 (has links)
In order to establish the rules and criteria· to be satisfied in order
to develop a scale model, which may be employed to predict the dynamic
behaviour of a fullscale rope-guide mineshaft installation, the theory
of the dynamic behaviour of rope-guides is considered. In order to
establish to what degree a scale model rope-guide system may be
expected to simulate the dynamic behaviour of its fullscale prototype a series of correlation test on an existing rope-guide installation and its dynamic scale model are described. A further series of model investigations into the aerodynamic scale
effects which may occur in rope-guide installations, are also described.
These investigations demonstrate certain limitations in the use of
dynamic scale models of rope-guides and also explain the mechanism of
air flow in shaftscontaining bluff bodies. On the strength of the experience gained in this research recommendations
are made for the execution of efficient experimental investigations into
the dynamic behaviour of various rope-guide mineshaft installations.
6ome information is also provided on the actual design of fullscale
rope-guide systems. / Thesis (PhD)--University of Pretoria, 1965. / gm2014 / Mechanical and Aeronautical Engineering / unrestricted

Šroubové spojení turbínového kola s hřídelem turbodmychadla / Design of thread connection of turbocharger turbine wheel and rotor shaftOboňa, Matúš January 2020 (has links)
This diploma thesis is focused on the concept of threaded connection of the turbine wheel and shaft. At the beginning are described current welding methods of the turbine wheel and shaft connections as well as methods of the compressor wheel and shaft connections. Four possible concepts were designed and evaluated, and the best concept was chosen. For this concept was calculated tightening torque and concept was evaluated in terms of turbocharger operating conditions.

Flexural Vibrations of a Rotating Shaft Having Nonlinear ConstraintsBonde, Umesh U. 06 1900 (has links)
<p> Flexural vibrations of a shaft mounted at each end on a non - linear spring have been studied. Theoretical analysis is carried out for the cubic non-linear spring. </p> <p> The effect of mountirig of a heavy rotor on the shaft has been considered. The stability analysis of the system is also given in the theoretical analysis.</p> / Thesis / Master of Engineering (ME)

Torsional stress concentration factor for hollow stepped shaftsTobin, Edmond William Jr. January 1949 (has links)
In this investigation the stress concentration factor was evaluated for a hollow stepped shaft with variable wall thickness and two fillet sizes. Electric strain gages of the SR-4 type were employed to measure strains in the fillet section.
Values of the stress concentration factor were determined with the ratio of inside to outside diameter ranging from 0.25 to 0.625. A decreasing relation was established between stress concentration and the internal diameter.
A satisfactory method of positioning gages accurately on the complex fillet surface was developed. This method featured an intermediate steel template with positive referencing. / M.S.
