The thesis pursues a design of mechanism for controlling the amount of air sucked by a turbocharger compressor. In the first part, there is a brief description of a turbocharger and its characteristics, in the second part the usual regulation methodologies are presented. Third, the main part describes the creation of the mechanism from concept drafts and their comparison, through the kinematic and force analysis of control parts, to the complete packaging a connection to the compressor housing. The fourth part is dedicated to the mechanism analysis in the terms of ability to perform as required.

Master’s thesis is focused on construction of testing stand for unit injector system mounted in Iveco Trakker engines. Testing stand can be with appropriate changes used for testing wide variates of unit injector systems. Simulation of computational model was computed in GT Suite software. Stress strength analysis was computed in Ansys Workbench 18.1 software.

In the Laboratory of the Experimental Biophotonics at Brno University of Technology, a new generation of the Coherence-Controlled Holographic Microscope (CCHM) is being developed. Because of the automation of certain microscope procedures, a fully motorized three axis computer controlled manipulator of the sample is to be employed. A fast and accurate lateral positioning in a range of several centimeters is required. For the focusing capability, very precise positioning in the optical axes is required as well. Initially, the basics of microscope manipulator design are presented. Then, commercially available solutions are introduced and compared with special focus on its possible implementation in the new generation of CCHM. However, due to the specific design of the new CCHM, available manipulators are not suitable. Therefore, a new optimized manipulator design is introduced in the second part of the thesis. A selection of its appropriate elements, especially actuators, is based on a review. For the new manipulator design, a technical documentation was made and a testing software was developed. A crucial part of the manipulator was assembled and tested.

The diploma thesis deals with a calculation and a construction concept of a balancing unit of a strait five cylinder combustion engine. The thesis contains the calculation and the construction concept of the balancing shafts. Also the concept of the calculation model of a driving mechanism with the balancing unit in MSC Adams – Engine is included.

This master´s thesis is focused on classification of corrosion resistivity magnesium alloy type AZ91 in environment of salt vapour testing in corrosion chambers. For tests were used samples of magnesium alloy manufactured by three different methods of casting: cast-iron mold, die vacuum casting, die casting without vacuum and method of die casting with additional pressure (squeeze casting). In this work was accomplished metallographic evaluation of corrosion attack and detailed analysis of corrosion products. Conclusions of exposits tests are assembled of analysis of influence of corrosion environment on structure of alloy. On the basis of these conclusions of corrosion tests were evaluated influences of corrosion speed [mm/year] on time [hours] for individual states of magnesium alloy.

The diploma work deals with design of lifting mechanism of overhead crane trolley with a load capacity 200 t. The main objective is design and analysis of selected components of lifting mechanism and components which are directly associated with lifting mechanism. Work includes design elements of a rope system, such as rope, rope drum, sheaves, sheave block, elements of the proposals of propulsion, such as engine, transmission, brake, coupling. The work contains also strength calculations of some components and drawing documentation.

In the introduction of master’s thesis is introduced the common identification with basics of friction, wear and mechanical losses. Master’s thesis includes description of solving losses by help of the MBS software and analysis of mechanical losses in the crank train. In the last part of work is introduced design for decrease mechanical losses in the crank train. At the close of master’s thesis are reviewed records.

Diploma thesis deal with possibility cam-shaft replacement of crank-shaft powertrain of combustion engine. In exordium work are designed basic engine data herewith type powertrain. Subsequently is designed several types stroke curves of lobe, after needs on course stroke. Further is in work elaborate engineering design body motor, in detail is solve construction body lobe. In last of capitol is evulate functionality virtual model. At the close are reviewed record and compared benefits and disavantages such engine type.

Diploma thesis is trying to analyze crank mechanism of a gas V-sixteen engine. Kinematics and balance crank mechanism are analyzed, dynamic model parameters are dermined, natural frequency of the torsional system are calculated, coupling parameters are designed and torsional problem with attached electric generator is analyzed.

This master’s thesis deals with kinematics model of blade rotating mechanism of turbocharger, which is called as VNT (“Variable nozzle turbine”). The first section treat of turbochargers generally, why we use them, summary description of construction and parts. In the next section deals with supercharge control, about types of controlling and theirs principles, of their vantages or disadvantages and comparison. Following section is about building kinematics model in software ADAMS. First step is analytics solving of mechanism, because it was necessary for parametric model. After this is described main model building. In the last section is kinematics model used on real turbocharger for checking results.
