Stress-deformation analysis of the high voltage transmission tower
Kuběna, Tomáš ; Pokorný, Jan (referee) ; Fuis, Vladimír (advisor)
The thesis deals with the analysis of a high voltage power pole near the village Lešná, whose collapse will cause an outage of the electricity network in the area. The model of the pole was created on the basis of drawings provided by Arpex Moravia s.r.o. The pole is designed as a truss system using the general node method, subjected to the weight of the structure, wind and the weight of live conductors. The analytical calculation is performed in Matlab and then verified by numerical calculation in Ansys Workbench. When the pole is subjected to all previously mentioned loads, the maximum deformation has a magnitude of u_max=18.89 mm, which is mostly affected by the wind action. The resulting safety to elastic limit state is k_MSP=23.95. The pole is operated with sufficient safety and collapse will not occur under normal operating conditions.

Topological optimization of a crane jib
Machara, Marcel ; Pokorný, Přemysl (referee) ; Zeizinger, Lukáš (advisor)
This bachelor's thesis deals with the issue of topology optimization in the design of structures and machine parts. The first part of the thesis consists of a theoretical summary of the current state of knowledge of crane jibs and their basic categorization. The second part consists of theoretical knowledge about optimization problems and the method of topology optimization. In the third part, an example of the implementation of topology optimization on a cantilever crane is processed using the Ansys Workbench software. The parameters of optimized jib designs are compared with the parameters of their basic models. At the end of this chapter, an evaluation of the results of topology optimization is performed.

Zeroshifting Transmission Mechanism Design
Mičola, Ivo ; Prokop, Aleš (referee) ; Svída, David (advisor)
This thesis deals with no delay gear shifting. The first part is devoted to theoretical introduction. The next part describes comprehensive approach to vehicle dynamics, the choice of gear ratios, the use of reverse engineering to model the interior of the gear housing and the actual structural design of the internal components and strength analysis. Moreover, this work should fill the gap in the available literature which is publicly accessible.
