Slit flow rheometer for magnetic and non-magnetic fluids
Železník, Tomáš ; Vimmr, Jan (referee) ; Roupec, Jakub (advisor)
In this thesis was designed, manufactured and tested the fourth evolution of a slit-flow rheometer with another necessary parts, eg. rheometer`s holder, drive frame and important jig tools. The rheometer is able to measure rheological properties of magnetic and non-magnetic fluids at very high shear rates, which commercial rheometers can not reach. It is designed for 200 bar pressure and maximum load 15 kN. The construction of the slit-flow rheometer with it`s holder and drive frame improves user friendliness, accelerates change of the fluid sample and expands research opportunities thanks to a big space for additional adjustments. It is possible to use different length of the slit and thanks to a changeable inserts it is possible to change parameters of the slit (roughness of the walls, wall material, thickness of the slit). A part of this thesis was focused on illation of necessary equations for planning calibration measurements. Aim of these measurements is to obtain minor pressure losses dependence on Reynolds number for specific slit.

Manipulator design for transport of SLM technology platforms
Železník, Tomáš ; Malý, Martin (referee) ; Koutný, Daniel (advisor)
The aim of the thesis is to design a manipulator for platforms from the machine SLM 280 HL, which is used in the laboratory of the Institude of Design. The manipulator will be used for transportation the platforms with a part from the machine into the tempering furnance. At the same time, the manipulator ensures safe removal of the platform from the machine so the machine and the part are not damaged. A special tool mounted on the platform is used for removing it. Thesis includes computational verification of dangerous places on the construction, manipulator stability and costs.
