The subject of the diploma thesis is the stress analysis of the circular and elliptical shaft from material jet grouting. A new advanced constitutive Shotcrete model will be applied on the material jet grouting. In the thesis, the shaft tensile strength factor and the size of the ground pressures will be primarily examined. The practical part of the diploma thesis is completed by the comparison of the analytical and numerical calculation of the normal force of the circular and elliptical shafts.

The thesis deals with a description and a strength analysis of selected parts of a modified supporting structure of a press part of a paper machine. The construction is designed to simplify a replacement of felt belts during a service shutdown of the machine. The first part of the thesis is devoted to a brief description of the paper machine with a more detailed focus on the press part. The next part of the thesis includes a project of adjustment to the original design of the supporting structure. The last part deals with a strength control of construction nodes of the adjusted project. A strength calculation is further divided into a calculation using the finite element method and an analytical calculation. Results of both previous calculation methods are compared at the end of the thesis.

Master’s thesis deals with design of single cylinder engine which is technology demonstrator of four cylinder naturally aspirated spark ignition engine Mazda Skyactiv-G. Outset of this thesis deals with construction of modern naturally aspirated engines and with comparison of their parameters. Computational part consists of forces in crank mechanism. These calculations are later used in FEM analysis of connecting rod.

This diploma thesis deals with design of a wheel hub assembly for a Formula Student vehicle. First part of this thesis is dedicated as an introduction to the Formula Student competition and serves as a summary of design solutions for wheel hubs with a focus on open wheel vehicles. Second part deals with description of a problem and summarizes necessary knowledge and information to solve given problem. Third part is devoted to CAD modelling in software PTC Creo parametric. This model is then analysed using finite element method. Last part of this thesis is a discussion about achieved results and discussion about further potential improvements is carried out.

This master thesis is about stress analysis of landing gear for accomplishment CS-23 regulation. The first part examines all alternatives of landing gear regarding for accomplishment of regulation. Next part is stress analysis of main and nose landing gear using FEM analysis in MSC Nastran software. Last part of master thesis describes topology optimization of two parts of landing gear.

The aim of this work is to analyse axisymetric tasks by norm ISO 7206-5, which is used to determination of static strength of ceramic heads. In the numeric analysis there will be considered form variances from nominal conicalness and circularity of stem sections i.e. possible variances caused by production. Furthermore form changes of recess inside of the head measured on real samples will be considered. All these variances from nominal values are necessary to analyse in more details, because they can participate in destruction of ceramic heads. The stem system, ceramic head and load cone (DHK) will be simulated as a 2D axisymetric task and 3D quarter symetrical task. That is why is necessary to undertake also comparing analysis of 2D and 3D tasks and compare results or eventually evaluate the error. This problem is solved using of Finite element System ANSYS 11.0.

The amphibious fullmetall plane Mermaid is made by company Czech Aircraft Works in Kunovice. Subject of this diploma thesis was involve changes of structure, which pass through during development, to calculation. Within this published work was process: Load calculation of wing Stress analysis of wing Load calculation of aileron Load calculation of flap Load calculation of horizontail tail

In this diploma thesis is completed the FEM analysis of connecting rod in combustion engine Briggs & Stratton of the garden lawnmower. Within the frame of computing in the FEM system ANSYS Workbench is solved static structural strein and stress analysis, buckling analysis a fatigue also. The boundary conditions for FEM computing come out from the kinematic and dynamic analysis of the crank-slider mechanism in combustion engine. The 3-D models of the crank-slider mechanism are created in parametric SolidWorks modeller. Own construction variants of the connecting rod based on results of FEM analysis are also designed.

Main object of the work is stress analysis of specific parts of tube and shell heat exchanger by using MKP. Each part is judged by two different computation methods. The method based on computation values and the method nearing real condition of operation of device. To approach real load are in the work made basic heat transfer computations for entire device and for analyzed part are computed boundary conductance by using CFD.

This master‘s thesis deals with strain-stress analysis of hip joint together with the final applied total endoprosthesis with Burch-Schneider cage. The main point of my work was to find the solution of stress–strain analysis state, which has been mentioned before in connection with Burch-Schneider cage. I describe the technique of geometric creation of whole body system, component´s materials or conditions which are neccessary for calculation. In coclusion there are results achieved in variants. In the first option the case of bone tissue was considered, which don’t reach degradation mechanical properties effect straining under Burch-Schneider cage. In some cases when the bone tissue is untimely forced, the necrosis of bone tissue takes place under Burch-Schneider cage. This possibility is described in the second option of type. For every option there was a case which was calculated with applied screw or without it. In all option mechanical features of cancellous bone tissue and their change influence on achieved results were considered. This problem was solved computational simulation in commercial software Ansys Workbench 12.0.
