Strength design of pipe
Jahodová, Miroslava ; Buzík, Jiří (referee) ; Horsák, Libor (advisor)
The subject of this thesis is strength design of pipe connecting furnace of continuous catalytic reforming with reactor. First is realize analytical design of individual parts according to ASME VIII, ČSN EN 12952-3 a ČSN EN 13480-3. It is also design and optimize supporting pipe using Caesar II. At the end of work is creating isometric documentation.

Three-cylinder in-line gasoline engine
Balash, Ievgen ; Kaplan, Zdeněk (referee) ; Píštěk, Václav (advisor)
The main aim of this master’s thesis is to design the powertrain of turbocharged threecylinder in-line gasoline engine based on given parameters. The work introduces three variants of balancing of inertia moment of rotating masses and balancer unit of first order moment of inertia of reciprocating parts. The thesis also presents calculation of torsion vibration of the powertrain and structural design of the rubber damper. In conclusion a stress analysis of the crankshaft is submitted with and without torsion vibration damper.

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.

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.

Adjustment of quick clamping equipment for application on screener crusher bucket
Hrňa, Lukáš ; Pokorný, Jan (referee) ; Pokorný, Přemysl (advisor)
This thesis deals with the adjustment of quit camping equipment for application on screener crusher bucket Allu SC 3-20 in order to streamline both digging into the bucket, and the actual screening. Using simulation methods in the Adams programme, forces are detected for the digging with the original suspension. Imperfections are revealed for the current full suspension and suggestions made for the new proposedsuspension. The new shape quick release mechanism is designed in CATIA modeler and the I-Deas programme provides final strength control of parts for the proposed mechanism. Finally, both variants are coMPared in terms of digging, sifting the material complexity of the design and the necessary restrictive criteria.

Strength analysis and optimization of the two-way excavator MH Plus S cab
Zavadil, Milan ; Janich, Miroslav (referee) ; Pokorný, Přemysl (advisor)
This diploma thesis deals with stress analysis and optimization of two-way cab excavator MH Plus S with total weight of machine 19375 kg. Stress analysis has been performed using the finite element method (FEM). As next step the structure design of protective frame and strength analysis of the cab and protective frame, which protect crew when the machine is rolled over protective structure (ROPS) according to ČSN EN ISO 3471 standard, have been made. The design documentation is a part of diploma thesis. This diploma thesis was conducted in cooperation with the firm Agrotec a.s.

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.

Hooclift NKH 8A340
Doleček, Ladislav ; Ospalík, Zdeněk (referee) ; Kašpárek, Jaroslav (advisor)
This master thesis analyses hook loader NKH 8A340. For calculation of load states was used the dynamic simulation in program MSC.ADAMS. This results were used like a input data to solve the construction with finished element method. After evaluation of results were made design changes of hook loader. Part of this thesis contains drawings of modified parts of hook loader.
