Master’s thesis is focused on a design of front uprights for Dragon 8 racing car of TU Brno Racing Formula Student team. This thesis follows up the bachelor’s thesis called “Race Car Front Wheel Carrier Design”. Discussion about team’s recent upright and component designs is followed by a model creation with use of topology optimization. Final geometry is simulated in FEA software. Design of the upright is then compared to the previous designs and also to its substitute produced with milling machining process.

This master thesis is focused on computational modelling of critical external as well as internal pressure acting of the repaired tank. During cleaning of pipelines, the gas mixture entered into this storage tank causing loss of integrity in the connection between the roof and the shell. The first part of the thesis is focused on check calculation of the shell in exceptional conditions. The next part describes the repair of the tank including check of the pillar according to ČSN EN 1993 1 1 and ČSN EN 1993-1-6. The main part of the thesis is focused on determination of the buckling resistances of the tank in original as well as repaired state using ANSYS Mechanical software. The results are comparable with original tank, whose buckling resistance was not decreased due to the repair.

The master thesis focuses on the strength calculation of piping with extra consideration given to the local effects of thermal loads. To be recognized as properly functioning, the piping is required to withstand the expected operating conditions in order to enable the continuous transport of the working fluid within the interconnected devices. It is imperative to take into consideration the variable thermal load in the area where the individual pipe branches connect into the main transmission piping. A major part of the thesis is concerned with the assessment of the expected workload influence on the most stressed parts of the system. The data are gathered by employing temperature and stress-strain analyses carried out in the ANSYS Mechanical program using the finite element method. The values based on the analyses are cross-checked with both the permitted values according to the ASME standard B31.3 Process piping and the ASME Boiler and Pressure Vessel Code stress categorization method. Since all the evaluated stresses are below their respective permissible values, the piping strength is concluded as satisfactory according to the standards.

This thesis deals with designing shape modifications of a toecap used in Honeywell brand safety shoes. The thesis shows algorithm of compression test and impact test FEA in ANSYS software. The toecap was divided into areas according to von-Misses stress. Several modifications were made in all areas separately, according to design of experiments. Best of the modifications were combined together and two best combinations selected. The goals were verified by experimental testing of manufactured toecaps. The results were even a little bit better than simulations.

The purpose of this thesis is to design a powertrain of petrol three-cylinder radial aircraft engine with the main parameters specified (bore, stroke, etc.), balancing inertia forces, stress analysis and determining of fatigue of the selected parts.

This master thesis focuses on structural analysis of combustion engine block. The main goal of this work was the design and compare individual solutions of long and short engine’s blocks. First part of work shows existing engine block designs and solutions. Based on the research part, the CAD design of the engine blocks and their discretization was performed by pre-processor programs. Structural analysis and their final comparison were provided by FEM and MBS programs.

This Diploma thesis presents possible proposals of welds number reduction frame doors for rail vehicles welded from profiles from aluminium alloy EN AW 6060, which is heat treated by temper T66. Profiles are welded by TIG process with additional material S Al 5087 (AlMg4,5MnZr). The heat treatment by the welding cycle causes a change in structure of basic material and decrease of mechanical properties due to dissolution of precipitates. To measure the necessary mechanical properties of the material after welding a tensile test was performed on the delivered samples. The resulting values from tensile test were subsequently used as cut – off values in the new door frame design by FEM simulation in Virtual Performance Solution software with PAM – Crash extension. The newly designed frame was welded according to the necessary welding procedure specifications, which are also part of the thesis. The conclusion is devoted to the economic evaluation of the current and new design of the door frame.

This diploma thesis deals with the modelling of the piezoelectric composite material using the finite element method. The thesis is divided into three parts. Research study is done in the first part. It focuses on the possibility of use of the piezoelectric layers as sensors. The second part concerns the homogenization of MFC (macro fiber composite). Material and piezoelectric parameters are obtained by modelling elementary structural cell under different loading conditions. Determined characteristics are verified with experimental data. The third part proposes the design of the experimental device, which allows the simulation of the rotor excitation by rotating unbalance. Excitation responses of MFCs placed in specific locations are calculated using FEA model of the device. The conclusion includes the description of the suitability to vibration measurement on the device.

The subject of this diploma thesis is to design a new construction of the machinery, which is used for manipulation with tire carts in rubber industry. The reason for the new design is to eliminate the main shortcomings of the existing provision. The aim of this project was to elaborate an overview of the current designs of the handling equipment in question and to subsequently construct a new suitable design solution. In addition, several conceptual calculations were needed to be used in the selection of the appropriate electric motor, transmission, pneumatic cylinders and wiring. The relevant parts were designed using structural FEM analyses. The several variants of the solutions were considered for a suitable construction design. Based on these FEM simulations, the relevant parts have been modified in terms of geometry so that the resulting manipulating machinery meets all the criteria, especially regarding safety.
