Numerická simulace svařování lopatky a rotoru turbíny. / Numeric simulation welding of the turbine vane and rotorDohnal, Ivo January 2010 (has links)
Numeric simulation welding of the turbine vane and rotor - master’s thesis is ordered by the Siemens Industrial Turbomachinery ltd. company. Simulation welding is done in program SYSWELD. Used welding materials are X22CrMoV12-1 (turbine vane), 30CrMoNiV5-11 (rotor), TOPCORE 838 B (additional material). These are temperature-resistant and fire-resistant welding materials. The SYSWELD program works on the principle of finite elements method. By SYSWELD is done the evaluation of temperature and stress fields and material structure after welding. Here is a part , which deals with computations of welding crevices.

Numerické modelování chování částicového kompozitu se sesíťovanou polymerní matricí / Numerical modeling of behavior of a particle composite with crosslinked polymer matrixMáša, Bohuslav January 2011 (has links)
The master's thesis deals with the determination of macroscopic behavior of a particulate composite with cross-linked polymer matrix under tensile load. The main focus of thesis is estimation of mechanical properties of a composite loaded by tensile loading using numerical methods (especially finite elements method). Investigated composite is composed of matrix in a rubbery state filled by alumina-based particles (Al2O3). Hyperelastic properties of the matrix have been modeled by the Mooney-Rivlin material model. Different compositions of particles, their different shape, orientation and different volume fractions have been considered. For all these characteristics of composite numerical models have been developed. The damage mechanisms of the matrix have also been taken into account. Results of numerical analyses have been compared with experimental data and good agreement between numerical models with damage mechanisms of matrix and experimental data has been found.

Ojnice plynového vidlicového šestnáctiválce / Connecting rod of gas V-sixteen engineLaštovica, Karel January 2011 (has links)
This diploma thesis deals with a design of a stationary engine connecting rod, its stress analysis and its safety factors. The thesis is divided into several parts. At the beginning there is a short research of connecting rods construction and a description of the engine. Then the main dimensions of a piston group and a connecting rod are defined and its 3D model is created. Next, the calculations of forces acting on the connecting rod in the crankshaft mechanism, are carried out. The following part deals with a stress analysis of the model created by MPK. From the obtained stress results, the safety factor at fatigue limit in chosen places of the connecting rod is calculated. In the conclusion, the results of the stress analysis and set safety factor level, are recapitulated.

Návrh moderního spalovacího motoru konstrukce V8 / Design of Modern V8 Combustion EngineŠebesta, Radek January 2011 (has links)
Master´s thesis is considered with design and construction of V8 combustion engine with small size and low mass of its body. In the construction were used mass-produced components from the other engines. From every component was generated a 3D model in computer program Pro/Engineer, new necessary parts were made in the same program and put together to assembly. Main part of the construction was to design a new crankshaft, a crankcase and an engine lubricating system. The crankshaft was subjected computing analysis in program Pro/Mechanica, using FEM.

Návrh jeřábu pro obecné použití, pro manipulaci na palubě plavidla / Design of General Service Crane, used for manipulation on the deck of the vesselDlužanský, Tomáš January 2011 (has links)
This master's thesis makes a brief comparison of design variants of cranes for general use on the deck of a vessel. Further, this thesis deals with a design of a crane with a telescopic jib and a single knuckle. An important part of the crane’s design is its kinematic solution, which was modified in the design phase. The last step of a simplified analytical calculation of the jib for design steel construction is given. This preliminary calculation is the starting point for a FEM model and for the following FEM analysis. A stress control is made according to the Lloyd's Register of Shipping agency’s standard for lifting appliances in marine environment and also according to the recommendations of Huisman company. A part of the proposed solution is a selection of main components of the crane. The master’s thesis contains a summary of some operational and other information which characterize possibilities of the crane’s use. This thesis also includes source materials for drawing documentation.

Analýza šíření tlakové vlny v aortě / Analysis of pulse wave propagation in aortaHolubář, Oldřich January 2011 (has links)
This master thesis is focused on usage of monitoring pulse wave propagation in aortic system in a field of diagnostic abdominal aortic aneurysm (AAA). There is a description of cardio-vascular system and its pathology in a form of AAA. A summarization of temporary diagnostic method was created and some new methods were proposed. This new methods presume monitoring of pulse wave propagation. Fluid structure interaction (FSI) analyses of pulse wave propagation were performed on simplified models of geometry which representing specific sections of aorta. The goal of these analyses was to prove usage of FSI method in a future development of proposed diagnostic methods.

Návrh geometrie kontejneru pro skladování ropných produktů / Design of tank container for storage of petroleum productsBezděk, Lukáš January 2011 (has links)
This diploma thesis presents design of oil storage container type ISO 1CC. The container is designed according to ISO standards. The standards prescribe or limit some of the container dimensions, other dimensions are derived from specific purpose of the container. The container can be considered either as a transport container (empty) or as a stationary tank (full). Therefore, the load conditions are given by ISO for transport containers in the first case and by ČSN EN for the latter. The goal is to design and evaluate various container designs by FEM (finite-element method) analysis.
