Design of a bath on the device for testing human joints
Svoboda, Tomáš ; Vrbka, Martin (referee) ; Čípek, Pavel (advisor)
The bachelor thesis deals with the design of the bathtub of an experimental device for testing human joints. Tribometer is used for experimental measurement of friction and visualization of real cartilage film in flooded synovial fluid. The result of this work is the design of air releasing, heating and sealing the bathtub in which the synovial fluid is located. By removing air bubbles and heating the liquid to the temperature of the human body, more accurate shear coefficient values and improved contact visualization are achieved. This should lead to a better understanding of the friction and lubrication processes in the synovial joint. The result of this work is chosen optimal design variant and production drawing documentation.

Overhead Line Protection against Climatic Effects
Sýkora, Martin ; Topolánek, David (referee) ; Orságová, Jaroslava (advisor)
The outdoor overhead lines are influenced by additional load pressure of wind and frost. These can have adverse reaction on outdoor conduction of the electric power. My bachelors' report deals with separate climatic effects and possibilities of their resolution. It it also concentrates on removing the negative influences caused particularly by wind and on the possibilities of liquidation of the frost that had already originated.

Measurement of mechanical and electrical quantities of bimetals
Kocian, Štěpán ; Bušov, Bohuslav (referee) ; Valenta, Jiří (advisor)
This bachelor thesis focuses on bimetals. In the theoretical part is described the principle of operation of bimetals, then important parameters of bimetal, including mathematical equations. Furthermore, methods of heating bimetals are mentioned and mathematically described. The last part in theory concentrates on the standards related to the use of bimetals as circuit breakers and the corresponding agreed breaking currents. The practical part deals with measurements on bimetal. This is measurement of free deflection and the force generated by the bimetal depending on the temperature change. From the measured data, the characteristics and the dependences of the properties for bimetal were processed. The last chapter was devoted to the creation of laboratory work.

Experimental chamber for testing of special materials using SLM technology
Malý, Martin ; Dočkal, Aleš (referee) ; Koutný, Daniel (advisor)
The thesis deals with the influence of process temperature and pressure on 3D printing using Selective Laser Melting. The aim of the thesis is the design, manufacture and testing of the experimental chamber for SLM 280HL from company SLM Solutions. The main task of the experimental chamber is to increase the temperature of the preheating of the powder bed from the original 200 °C to at least at 400 °C. The device will be used to investigate the influence of high process temperature on the properties of printed materials. The thesis also deals with the design of the powder applicator for elevated temperatures.
