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
