Buckling Analysis of Thermoplastic Pipes
Procházka, Martin ; Kytýr, Jiří (referee) ; Gratza, Roman (advisor)
This thesis deals with buckling analysis of thermoplastic pipes. An experiment was conducted in which the pipes were encumbered in axis. During this experiment, the loading force was monitored and measured at the material stability loss. For these measurements, polyethylene, polypropylene and polyvinylchloride pipes were used. Afterwards, the static and buckling analysis of pipe models were made in the ANSYS programme. The models were created on the basis of the experiment results. The outcomes of the analysis were compared with figures of the theoretical calculations. In the ANSYS programme pipes were strained by external overpressure.

Stress and strain analysis of connecting rod in combustion engine using FEM
Biječek, Tomáš ; Hutař, Pavel (referee) ; Vaverka, Michal (advisor)
In this diploma thesis is completed the FEM analysis of connecting rod in combustion engine Briggs & Stratton of the garden lawnmower. Within the frame of computing in the FEM system ANSYS Workbench is solved static structural strein and stress analysis, buckling analysis a fatigue also. The boundary conditions for FEM computing come out from the kinematic and dynamic analysis of the crank-slider mechanism in combustion engine. The 3-D models of the crank-slider mechanism are created in parametric SolidWorks modeller. Own construction variants of the connecting rod based on results of FEM analysis are also designed.

Design of a biological organic waste conveyor
Diviš, Přemysl ; Zajíc, Zdeněk (referee) ; Pokorný, Přemysl (advisor)
The master thesis deals with the design of a convex conveyor belt for biological organic waste, with a focus on the mass optimization of its supporting structure. The thesis assignment was developed in cooperation with Bluetech s.r.o. The aim of the work was to perform a functional calculation of the conveyor belt and to complement it with the selection of components. One of the objectives was also to perform a strength analysis of the original supporting structure and to perform its mass optimization from the collected data. The main part of the work is devoted to design the shape of the new support structure, where the resulting weight and the values of the maximum stresses will be lower than the original structure. The conclusion displays summarized results and suggests possible recommendations.
