Force loading of milling tools during the machining process
Procházka, Luděk ; Slaný, Martin (referee) ; Polzer, Aleš (advisor)
The thesis deals with the problem of force loading during machining of thin-walled parts. In the theoretical part, the force load applied during milling and the possibility of measuring of the force loading during milling is analyzed. Further the work focuses on the machining of thin-walled parts, problems in machining of these parts and the possibility of eliminating these issues. The practical part deals with the design and realization of the measurement of the force load on the selected components. The thesis also presents a comparison of the simulation model of deflection of thin-walled parts with the values measured in real machining.

Calculation of natural frequencies of a bar system using finite element method
Svoboda, Petr ; Kubík, Petr (referee) ; Návrat, Tomáš (advisor)
The task of the presented bachelor thesis has been to program an algorithm of the finite element method to calculate natural frequencies of beam systems. To solve this problem a freely available SW products (Python, libraries NumPy, SciPy, Fortran compiler etc.) should have been primarily used and thereby to check possibilities of freely available SW product application in science purposes in the field of the Continuum Mechanics tasks. For a functionality verification of the program the ANSYS code is to be used.

Static analysis of the prefabricated hall
Holiš, Ondřej ; Hokeš, Filip (referee) ; Vlk, Zbyněk (advisor)
This thesis is aimed at the calculation of inner forces and deformations of three-aisled, one-storey, industrial hall. For the structural analysis the integration of the elastic curve method has been used along with Mohr´s method for calculation of deflections. The problematics of sloped beams and their influence on the structural behaviour of the construction has also been included in this thesis. For the calculations and diagram plots the programmes such as SMath and MathCad have been used.The results have then been compared with multiple planar models of the construction made in the RFEM 6.02 programme.
