The purpose of this thesis is two-cylinder in-line four stroke petrol engine design based on input parameters. The work consists of different variations of designed crankshaft balancing and balancing unit. Calculation method of torsion vibration and crankshaft fatigue failure solution based on stress analysis are included.

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.

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.

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.

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.

This diploma thesis is focused on design of adsorber. Rule CSN EN 13 345 is used to calculate of design adsorber. Finite element method (FEM) is used tor stress analysis a categoration of the stress.

This diploma thesis deals with stress analysis central joint of forest forwarder LVS 511. Stress analysis has been performed by finite element method (FEM) using the program NX I-deas. The diploma thesis was conducted in cooperation with the firm Strojírna novotný s.r.o.

External fixators are used in a treatment of complicated fractures and their properties have a crucial impact on treatment quality. Therefore, this thesis is concerned with a biomechanical study of a bone (tibia) with applied external fixators via strain-stress analysis and their comparison with a state of tibia without applied fixator (physiological state). After creating the volume models of geometry of tibia and seven variants of external axial fixators, the corresponding finite element method (FEM) models are created. The analysis of tibia without applied fixator and tibia with all studied fixators is made for three states of load which correspond to characteristic load states during the first stage of treatment. The strain-stress analysis is made using finite element method. Furthermore, the methods of displacement and rotation evaluation during loading are proposed. One can conclude from the results of the strain-stress analysis how the different variants of fixators prevent the displacement and rotation of the bone during the different load states and the comparisons with the physiological state of bone are made. Bone tissue loading is determined from the distribution and the values of the first and the third principal stresses. Finally, comparing the results of all variants the influence of the fixator length, the gap between the fixation elements near the fracture, the number and the setting of the fixation elements on the fixation properties is analysed.

This thesis describes an analysis of the design of the bolted connection pivot plate-wheel of bucket wheel stacker-reclaimer loader. The challenge solution is to decide whether the current design is suitable. The thesis contains comparison of calculation according to VDI regulation with the ČSN, performing stress analysis using FEM calculation model and a design of changes, joint bearings with steel structures.
