This thesis deals with the issue of founding wooden structures above the ground level, i.e. with the existence of a crawl space between the ground and the floor structure. The thesis focuses on the utilisation of numerical methods for describing behaviour of the crawl space and its effects on temperature in adjacent structures. The methodology deals with the possibilities of determining thermal conductivity of air in the crawl space, which is a necessary input for a modal analysis in the ANSYS environment. Further, models with various levels of ventilation, crawl space shape, and material composition of the floor structure were constructed. These models served for monitoring temperature within the floor structure and for evaluating the level of influence of changed crawl space parameters.

This thesis acquaint readers with typology of rope lashings including possibilities of their use. Two the most used types of lashings - square and shear lashing - were experimentally tested. A numerical model of these lashings in many variants was defined and analyzed, based on the tests. Selected results of tests and numerical analyses were evaluated and compared. At the end of the thesis the basic principles of lashings use are formulated.

The diploma thesis deals with the creation of a detail FEM model all-composite wing of glider. Reduction created FEM model of the beam model. The models are calculated natural frequencies, vibration shapes wings and then subsequently compared the results of analyzes of both models.

This Master thesis is focused on electromagnetic brakes for servomotors. In the first chapter is described principle of operation, later then design and main parameters are explained. The main part of thesis is focused on calculation of dynamic parameters of electromagnetic brakes. Calculations are solved first by analytic method in Matlab–Simulink, then by finite element analysis. Results are compared with measurements on prototype brake.

The aim of the diploma thesis is the design of mechanical parts of the rear axle driveline suitable for rebuilding of a given sports car into an electric car. The introductory part briefly explains the physical principles of the drive and contains a brief summary of the current concepts of electric vehicle propulsion. Afterwards, there is a comparison and selection of a suitable concept for a given electric vehicle, determination of the basic vehicle parameters based on the calculation of the longitudinal vehicle dynamics and the gearbox calculation on the basis of which the design is solved. The next part is dedicated to the computational inspection of parts using the finite element method. The final part deals with the placement of the assembly inside the vehicle and the evaluation of the drive mechanism.

The thesis deals with the design of the drilling rig tower. The goal of the diploma thesis, which is created in cooperation with MND, a.s., is to design a steel structure. Then perform a load analysis. Further, to perform a structural analysis using the Finite Element Method and to optimize the design.

The master thesis deals with the computational simulation of cross-roll leveling of tubes with various degrees of thickness. Based on the Lagrange approach, a several FEM models of curved tube were developed and subsequently solved in ANSYS commercial software. Furthermore, a several models of curved tube were solved by algorithm based on the Euler approach created at UMTMB FME BUT. Based on the comparison of output parameters from both algorithms it was found that the output parameters are comparable to the d/D ratio (inner/outer diameter of the tube) = 0.43.

Master thesis analyzes rotary draw bending of the tubes without using a mandrel. Bending process is accompanied by many defects due to large displacement of formed material. One of the major defects is flattering of the cross section also called ovality. In order to decrease ovality comes up a proposal of the changes to the tool design. Modifications of tool’s geometry are numerically analyzed by finite element method in software ANSYS. According to the results of the simulations an optimized pressure die is manufactured. Several experimental tests are accomplished to verify the effect of the optimized tool design. Approximately 100 bends confirm a decrease of ovality using modified pressure die.

Hlavním cílem této práce je analýza napěťových polí, indukovaných dvojčatěním ovlivněných přítomností precipitátu před čelem dvojčete. Zvolený případ popisuje tahové dvojče {1012} 101 1 s lamelarními precipitáty v hořčíkové slitině AZ31. Systém je modelován metodou konečnýh prvků jako 2D elastická eliptická inkluze, se dvěmi elastickými precipitáty tyčovitého tvaru, nacházející se před čelem elipsy obklopené plastickou matricí modelovanou pomocí krystalové plasticity. Analýza dvojčat a precipitátů s různou tlouštkou ukazje inhibující účinek precipitátů na růst tloušťky dvojčat. Velikost tohoto účinku se mění s tloušťkou dvojčete v důsledku komplexní interakce mezi dvojčetem precipitátem a indukovanou plastickou zónou.

This diploma thesis deals with completion of the calculation FEM stress analysis of current type of CI - engine piston construction. Then it deals with design of new types of CI - engine piston construction including of their stress analysis. Analysis of advantages and disadvantages of single types of construction is made on the basis of results comparison.
