The subject of this diploma thesis is to optimize the shield of asynchronous motor. In the thesis are given results of modal and the strain-stress analysis made for model of the shield, which is currently produced. To resolve this issue was used CAE programming system Pro/MECHANICA, which is based on method of geometric elements – GEM. The main output of this work is proposal of two new optimized shields of asynchronous motor and for these are presented results of modal analyse and the strain-stress analysis. Part of the thesis is design and technical-economic evaluation of casting methods for new shield production.

The purpose of this work is to find optimal design for mounting cryogenic tank into ISO container frame. Solution is based on stress analyses of several designs and theirs interpretation. According to standards, set of tests, which all cryogenic containers have to pass before being put into operation, is created. Designs are tested by final element method using software ANSYS. At first, results of the stress analyses provide base for improvements targeted to better meeting with needs of the standards. In final stage, the results participate in optimum design selection.

The main aim of master’s thesis was to handle the computing proposal and the construction design of the powertrain of racing Wankel rotary engine with 300 kW power output and in the case of 9000 speed per minute. On the basic of these values was made the primary design of the rotary engine, design of the eccentric shaft and rotor housing. Mechanical stress and torsional vibrations of the eccentric shaft were analyzed by using the course of indicator diagram.

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.

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.

This master´s thesis deals with a proposed design of the derrick of the filling car of a coke-oven battery, which is used for working with unit loads, repairing and maintenance of the filling car and cleaning of the battery risers. In the first part a solution concept was chosen. For this concept a main steel structure was designed, which was controlled in stress analysis by the FEM program I-DEAS NX 11. Further, the main parts of the lifting and travelling mechanism were calculated using specified parameters. In the conclusion of this thesis the results summary of specified targets is stated. Assembly drawing is in the annex of this thesis.

Currently, the wear of the articulating surfaces in contact have a significant influence on the life of hip joint replacement. It is therefore desirable to determine the influence of certain aspects on the wear of replacement. For this reason, master´s thesis deals with the influence of asperities of real surfaces of the hip joint replacement on its wear. The aim is to create computational models that would correspond to the real surface of the scanned prosthesis, performing strain- stress analysis and comparison with the results without the presence of asperities.

The purpose of this thesis is the design of a radial spark-ignition engine in two layout variations, the stress analysis of selected components using the finite element method, the eventual optimization of selected components and the determination of safety on their most strained locations.

The topic of this master´s thesis is the strain-stress analysis of the spacer-spring for the swivel light projector of car headlamp. The spacer-spring is used for delimitation of moving swivel light projector in relation to turning drive. During vibration test there is a danger of limit state of fatigue failure.

The present master thesis deals with the design of wheel disk for passenger car. The review part of this thesis summaries the history and development of the wheel; this is followed by a description of individual construction types of wheel disk for passenger car presently used. The construction part of this thesis provides a design of disk of given parameters based on the analysis of forces acting on the car wheel. For the purposes of design, the stress and fatigue analyses are performed.
