Stand for Single Cylinder Engine Testing
Sikora, Ondřej ; Prokop, Aleš (referee) ; Janoušek, Michal (advisor)
The diploma thesis deals with construction design of stand for testing single-cylinder turbocharged engine. The first part describes principles and possibilities of measuring the performance parameters of internal combustion engines. It also analyzes the issue of measuring single-cylinder combustion engine. The main part of thesis is about construction design of stand, which describes the individual technical solutions of the general construction parts. The last chapter deals with numerical simulation, which uses modern software tools. This software helps with verification of function design.

Computational simulation of vibrations of rubber damper
Krupa, Lukáš ; Návrat, Tomáš (referee) ; Burša, Jiří (advisor)
This thesis deals with computational modelling of rubber damper using Finite element method (FEM). This thesis includes experimental measurement of material properties of rubber subjected to static and dynamic loading and their implementation into viscoelastic and hyperelastic material models with respect to given task. Dependance of dynamic stiffness on loading frequency obtained from the simulation is validated with experimental measurement. In the end the difference between results is investigated and possible causes of that are introduced.

Manufacturing of pressed metal part
Rubáš, Petr ; Peterková, Eva (referee) ; Podaný, Kamil (advisor)
The thesis focuses on the design of the technology of manufacture of metallic insert that is included to the shock absorbing element of truck axle silentblock. The insert is made of ´U´ profile metallic sheets with bent edges at both ends, thickness 2 mm. What was chosen as the most fitting technology based on manufacturing requirements and production series size of 160 000 units per year is conventional tool bending. The required form of the insert is achieved by two operations: in the first step, both metallic sheet edges are preliminary bent and in the second step the central part is bent to the ´U´ form. The material chosen for the manufacture of the insert is micro-alloyed structural steel S 315 MC the mechanical properties of which match requirements of the finished product. The part will be manufactured on eccentric press LEXN 100 C and its production cost is CZK 4.60.

Measurement of vehicle suspension bushing characteristics
Kopecký, Petr ; Zháňal, Lubor (referee) ; Porteš, Petr (advisor)
This master’s thesis deals with the measurement of static characteristics of wheel suspension bushings. It includes a structural design of the test device and drawings according to which the device was manufactured. The device has several variations for different stresses and is applicable with possible modifications to various bushings including the ones that do not have common axes. The measurement procedure, the results of the measurements of the static characteristics and their analysis and comparison with the finite element method calculations are also given. The measured characteristics were then added to the model of the axle for multibody simulations.
