Numerical analysis of rubber bushing assembly
Novotný, Tomáš ; Rekem, Jakub (referee) ; Dlugoš, Jozef (advisor)
This diploma thesis deals with different approaches to the numerical simulation of the assembly of a chassis unit consisting of a rubber bushing, a stabilizer tube, a clamp and a fixture that simply represents the vehicle frame. The goal is to compare individual numerical simulations and find the most suitable methodology for this process. The first part of the thesis is devoted to the theory focused on the issue of nonlinearities in the finite element method. It provides important knowledge for the creation of the practical part. The second part contains the procedure for the design and creation of individual methods of numerical simulation of the assembly of chassis components. In the last part of the work, the results obtained from the individual simulations are evaluated, their mutual comparison and verification of the calculated data with a real experiment is carried out. Final recommendations were established based on the information obtained.

Diagnostic and improvement of electrical contact
Hrdý, Branislav ; Kuchyňková, Hana (referee) ; Veselka, František (advisor)
The aim of bachelor thesis is create a summary overview of terminals, to obtain information about contruction, materials of the conductive parts of the terminals and its snap methods. The next goal was description of methods of conductors’ construction and snap methods of its con-ductors. All processed information is obtained from the technical literature and from practical knowledge acquired during the measurement and monitoring of analyzed terminals. The final goal was to create an animated 3D model of terminal as a sample of main process of terminals’ working principle. In conclusion of this work is comparison of terminals, and their properties, facts observed during measurement or testing.

Special induction machine as source of electric energy
Dušek, Jiří ; Janda, Marcel (referee) ; Skalka, Miroslav (advisor)
This work deals with description of an induction machine principles for both of motor and generator operations. Then is been described a special kind of an induction generator working into an isolated system. The construction of an induction generator was designed with two stator winding connection due to possibility of the variable number of pole pairs. Also there is an excitation capacity design for self-excitation. Last part of this work contains the measurement of an induction generator with different values of excitation capacity and both terminal clamps connection.
