Stress-strain analysis of front seat folding mechanism
Gergeľ, Erik ; Gašparec, Andrej (referee) ; Skalka, Petr (advisor)
This master thesis deals with creation of computational model for stress - strain analysis of front car seat folding mechanism. The calculation has been done using FEM for static and dynamic load case. The results displayed the critical area of mechanism and determined the value of force when the safety of mechanism is not guaranteed and the force when the mechanism failure occurs. According to results from both load cases was made a statement that is necessary to model the dynamic load cases respecting the load time course.

Modifying profile design of the door leaf for rail vehicle
Lysák, Jan ; Hruzíková, Miroslava (referee) ; Majer, Zdeněk (advisor)
This master thesis deals with creation computional model of specific door leaf which was researched and now is provided by company named IFE-CR, a.s. Finite element method analysis is performed within the standards for load conditions during the operation. Stress-strain response should be the main factor to comparing results with experiment on real door. Based on acquired knowledge from the original model we can evaluate credibility of mechanical behavior of newly designed model which has lower profil tapered from the original 42 mm to 25,4 mm. From the results of FEM analysis of the modified profile is evaluated applicability to the real operational state. At the end is quantified material and financial savings achieved by reducing the height of profile.

Stress-strain analysis of cast-iron grate
Slunský, Jan ; Vosynek, Petr (referee) ; Návrat, Tomáš (advisor)
This bachelor’s thesis deals with the analysis of strain-stress cast iron grate. The problem was solved in the ANSYS finite element method. It was established calculation model and it performed stress deformation analysis. The calculations were subsequently designated a dangerous place and set security to the limit state flexibility and crack units. There was also a practical load test test.
