Bezkontaktní měření povrchových teplot při obrábění kovových materiálů / Non-contact measurement of surface temperatures during machining of metal materials

Trojan, Jiří January 2015 (has links)
This Master’s thesis deals with non-contact methods of surface temperature with machining metal materials. This work contains summary of basic terms and description of thermodynamics laws. Furthermore, the work present criteria for selection suitable measuring equipment. In the second part of this work is described experiment focused on drilling technology and measurement dependence of temperature on different cutting speed for different drilling approaches. At the end are presented the results.

Termografie ve strojírenství / Thermography in engineering

Koten, Jakub January 2016 (has links)
This work deals with non-contact measurement of surface temperatures. The aim of the first part is to explain basic terms, principles and ways of measuring temperature. Furthermore, there is an overview of thermal imagining cameras usable in industry. In the practical part there is a theoretically suggested experiment, which monitors the dependence of the surface temperature on the size of the cross-section of the workpiece during the turning under unchanged cutting conditions. Experimental measurements are executed with using thermocamera ThermaCAM SC 200 and they are evaluated in software called Researcher.

Teplotní vlastnosti automobilových zdrojů světla - Halogenové zdroje / Thermal properties of automotive light sources - Halogen sources

Hlubinka, David January 2017 (has links)
The aim of master´s thesis is to get acquainted with the design and materials used in selected automotive light source – tungsten halogen lamp. Further, the thesis focused on the theory and appropriate selection of the thermal measurement method on a real sample. Subsequently, a model of the light source and its simulation in the ANSYS – Maxwell 3D and Mechanical programs are created. Finally, the results of the thermal simulation and the non-contact measurement of the tungsten halogen lamp are evaluated

Zařízení pro měření tepelného odporu rukavic / Apparatus for measuring the thermal resistance of the gloves

Pelikán, Jakub January 2016 (has links)
This thesis deals with common problem health protection at work. Namely hand protection during the work in very cold environment. It’s an analysis of materials suitable for apparatus used for measuring the thermal resistance of the gloves. There was analysed a range of materials. Every single sample was tested for heat conductivity and afterwards was assessed the suitability of materials. Heat was generated by electricity. Ocured heat fields was assessed with thermocamera. After performed experiments of carbon fiber we haven’t reached any satisfying results which we could use for manufacturing of this device. On the other hand kapton film has given very interesting results which we would recommend eventually. Kapton film needs to be modify according to the method listed in the conlusion. This thesis gives us a clear overview and inspiration for additional research of this device. It finds it’s place in research facilities and companies manufacturing protective clothing.
