Spark ignition engine for small passenger car
Fáber, Filip ; Novotný, Pavel (referee) ; Píštěk, Václav (advisor)
The aim of this master’s thesis was to define force progression in crank-type mechanism from the set parameters of the cylindrical unit. Furthermore, the design of the possible balance of this crank-type mechanism with one balancing shaft was realized. The calculations of torsional vibration and stress analyses of the designed crank-type mechanism were realized too.

Formula Student Pedal Assembly
Skula, Libor ; Dundálek, Radim (referee) ; Ramík, Pavel (advisor)
This thesis is concerned with design of pedal box for Formula Student vehicle. Summary of design solutions is presented in introductory chapter, especially those used in Formula Student competition. Designed assembly is divided into parts of single pedals and base plate. The proposed design is supported by stress analysis of loaded parts in pedal box. In conclusion, design is reviewed in terms of the results, as well as compared with current pedal box.

Stress analysis of the tree root of an aircraft engine turbine wheel
Čepica, Vojtěch ; Svoboda, Miroslav (referee) ; Chromek, Lukáš (advisor)
The main focus of the bachelor thesis is stress analysis of the tree root of an aircraft engine turbine wheel. First part is dedicated to the issue of aircraft engine and various kinds of mounting the rotor blades. Next chapters of the thesis involve the calculation itself. The known equatations have been used in case of analytical calculation whereas the ANSYS Workbench program based on final element method has been used for the numerical calculations. Finally I compared both approaches in conclusion of the thesis.

Hydraulic pullers
Kvasnica, Tomáš ; Malach, František (referee) ; Malášek, Jiří (advisor)
This Diploma thesis occupies with design of hydraulic puller. In work are mentioned possible types of construction. Choice construction of puller is disposed with parameters: maximum pushing force 50 kN, speed of piston rod 0,05 m/s. This work also contains FEM analysis by computer programme I-DEAS. The work also occupies with design of fluid drive.

Stress-strain analysis of a sclerotic artery during angioplasty
Trtík, Adam ; Fuis, Vladimír (referee) ; Burša, Jiří (advisor)
This bachelor thesis focuses on an analytical calculation of maximum stress and deformation in arterial wall suffering from atherosclerosis during angioplasty and compares this value to the stress in wall of both healthy and sclerotic artery loaded by normal systolic pressure. Finally, the results are compared with corresponding model using the finite element method. In the theoretical part, the histology of arteries, their biomechanical properties and pathogenesis of atherosclerosis itself are briefly described.

Deformation, stress and safety analysis of the bicycle frame.
Ondrejka, Jan ; Vosynek, Petr (referee) ; Vrbka, Jan (advisor)
The aim of this bachelor thesis is to assess complience and safety of the bicycle frame with basic elasticity approach, namely by deformation and stress analysis. After model simplyfying, two different cases were made. Difference between these two were in loads aplied on the frame. Maple 12.0 softwarre was used for calculation, Autodesk Inventor and AutoCAD were used for sketches. The results were checked with ANSYS Workbench.

Stress analysis of the total hip joint endoprosthesis head under oblique loading
Janovský, Martin ; Janíček, Přemysl (referee) ; Fuis, Vladimír (advisor)
This diploma thesis is concerned with the stress analysis of the total hip joint endoprosthesis ceramic head under oblique loading. Load was obtain from experimental in vivo measurement on three patients, whereas two of them was the same weight. As input variables were use contact forces, especially knee bend and standing on one leg. Furthermore they will be considered shape deflections from ideal cone, especially circle deviation, cone deviation and cone plus circle deviation together.

Bucket-wheel boom of stacker/reclaimer
Štursa, Martin ; Krása, Jakub (referee) ; Pokorný, Přemysl (advisor)
This master’s thesis deals with the construction of parts of a bucket-wheel stacker/reclaimer designed to operate lignite stockyard at coal power plant. First the basic parameters of machine and loads applied in service are defined. The work also includes the design of steel structure of bucket-wheel boom, bucket-wheel, buckets, bucket-wheel drive, shaft, bearings and other parts of bucket-wheel boom. These parts are verified by analytical or finite element analysis.
