Protective Guards of Machine Tool
Zlámal, Josef ; Učeň, Oldřich (referee) ; Novotný, Lubomír (advisor)
The master thesis deals with the problematics of machine guard. The first part of the thesis is focused on the analysis of machine guards, legislative safety requirements and noise issues. The second part of the thesis describes design and construction of the machine guard in case of the vertical turning centre, TOSHULIN - POWERTURN 2000, including the calculation of noise reduction.

Design of Turbine Safety Cover for Turbocharger
Mach, Petr ; Kudláček, Petr (referee) ; Novotný, Pavel (advisor)
This diploma thesis deals with the issue related to the burst covers of turbochargers, followed by the design of the safety cover for turbine housing, which works as a protective barrier in case of possible destruction of the turbocharger rotor. The design is created according to current knowledge from the containment testing and requirements for the highest level of safety during turbocharger operation. In this diploma thesis, there are made 2 new variants of burst cover. The first aims at a lower purchase price and it is suitable for applications where it is not necessary to have the highest protection level. The second variant aims to face the strictest conditions and uses reinforced walls, which makes it a more expensive product. For both designs of the burst cover, there is made an analysis of vibrations due to long-term trouble-free operation, which is followed by further modification of the design. In the last part, burst covers are checked for high-cycle material fatigue. The output of this diploma thesis are therefore two new designs of the safety covers that are suitable in terms of vibrations caused by the internal combustion engine.
