Analysis of railway behavior on vehicles effects
Peňázová, Gabriela ; Kala, Jiří (referee) ; Salajka, Vlastislav (advisor)
The master’s thesis deals with the possibilities of railway track modeling. The computational models were created in ANSYS Classic. Simplified 2D model represents a longitudal half of classic single track construction, 3D models represent classic single track construction and RHEDA 2000 slab track. Static and dynamic response of 2D model was compared with analytical solutions by Timoshenko and Fryba. Static and dynamic responses of 3D models were analyzed and compared.

Research study of „Tilt pad bearings“ (computational and experimental modelling)
Havlásek, Michal ; Chlud, Michal (referee) ; Malenovský, Eduard (advisor)
The bachelor’s thesis is focused on the computational and experimental modelling of the tilting pad bearings. The computational and experimental modelling is based on solving the lubrication theory provided by English professor Osborn Reynolds, published in 1886. The main part of the thesis is the description of the most widely used computational models, especially TEHD analysis, and the description of the only two experimental devices for the testing of the tilting pad bearings. The thesis is supplemented with the prediction of the development of the computational modelling in the near future.

Design and construction of the task to the subject PPI
Král, Jiří ; Krejčí, Petr (referee) ; Návrat, Tomáš (advisor)
The bachelor thesis deals with creating of computational model for definition of tensity and deformations of bars system. Then the physical model is made according to the theoretical model. This physical model is used for educational purposes. Next step is measurement of stress and deformation of bars. The final part is focused on eventual variations between theoretical and real model.
