Concept for a 5 axle trailer / 4 axle trailer with replaceable bodies
Šeda, Pavel ; Pikula, Michal (referee) ; Kašpárek, Jaroslav (advisor)
This thesis describes the design concept five-axle balanced trailer / four-axle semi-mounted trailer with swap bodies. The initial point of this work is the search of possible solutions both. The second part of the justification for selection of the very concept design proposal is selected variants. Another point of this work is the analysis of the strength of the chassis frame. Control is mainly engaged deformation and strain analysis in different Load case. The thesis is also drawing documentation. This thesis was developed in cooperation with ZDT Nové Veselí s.r.o.

Strength and lifetime analysis of the hydraulic key lock
Klíč, Jan ; Majer, Zdeněk (referee) ; Vrbka, Jan (advisor)
Theoretical part of this master thesis is focused on the theory of fatigue life. The second part deals with the assesment of static strength the closing flap in front of water turbine. Futher fatigue analysis of the closing flap is performed considering corrosive environment. The aim is to verify the required service lifetime of 50 years.

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.

Design of Conveyor Semi-Trailer
Nepovím, Ondřej ; Kovář, Stanislav (referee) ; Pokorný, Přemysl (advisor)
The first part of the thesis focuses on a research study of high-strength steels. The thesis also includes a conceptual design of the supporting structure of a transshipment trailer, which uses high-strength materials. This design is compatible with the Herkul trailer produced by the company NovaSteel s. r. o. and distributed by the sales network of Romill Brno, spol. s r.o. In its final part, the thesis deals with a stress analysis of the proposed design of the transshipment trailer. Stress-strength and deformation tests were carried out by means of the finite element method.

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.

Rear frame of Forwarder L520
Koumar, Martin ; Klimeš, Pavel (referee) ; Pokorný, Přemysl (advisor)
This master’s thesis deals with strength analysis rear frame of forwarder LVS 520 and propose modifications of this frame. The main part of this work is strength analysis of the supporting frame of the original construction by the help of the finite elements method. Further the design of suitable structural modifications and strength analysis of the modified construction of frame. This master’s thesis has been prepared with Strojírna Novotný s.r.o. company cooperation.

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.

Rail undercarriage of stacker/reclaimer
Schűssel, Jiří ; Krása, Jakub (referee) ; Pokorný, Přemysl (advisor)
This diploma thesis deals with rail undercarriage of stacker/reclaimer used in thermal power plants. The paper focuses on a conceptual framework of two-track bogie rail undercarriage and on a calculation of maximal load of undercarriage wheels within operational processes. The results are used for a design of two-wheel driven bogie and its main parts. The next part of the thesis presents finite element method analysis of a designed bogie along with a projection drawing. The diploma thesis was elaborated in cooperation with a company NOEN a. s.

Jib crane for handling metal plates
Dobšíček, Tomáš ; Prachař, Vlastimil (referee) ; Škopán, Miroslav (advisor)
This diploma thesis deals with the construction design of revolving column crane which is used for manipulation with metal plates for metal shears and bending bench. The aim is to set main proportions and basic parameters for the designed steel construction via design calculation. Then the thesis deals with checking of strength analysis done by programme I-DEAS NX 11. Suggestion of disposal placement of the crane, choice of hoist, travelling system, auxiliary device and drawing documentation are also parts of the design.
