This thesis deals with dynamic behavior of rotor dynamics system vibrating in a liquid. Work is factually oriented on influence of the liquid to natural frequences of rotor of vortex turbine. There is described the creation of geometric and computational model of the system and the results of natural frequences and damping in dependence on environment are presen-ted. There are compared variations in natural frequences of the rotor system, which are caused of the interaction of the various level of the water environment. The step of integration are tested and compared for choise solving method. Problem is solved by computational simulation in commercial software ANSYS 11.0 There is used software tools Multiphysics/FSI.

Master thesis is about increasing of protection the crew in race car with changes in its roll-over protective structure according to current safety rules. For examination was used the Finite Element Method. The products of this thesis are different variation of roll cages, which are tasked to increasing the safety of existent race car.

Obsahem této práce je numerická simulace dvoudimenzionálního proudění nestlačitelné vazké kapaliny. Uvažujeme rotující elipsu soustředně umístěnou v kružnici. Prostor mezi elipsou a kružnicí je vyplněn kapalinou. Cílem je popsat proudění kapaliny vyvolané otáčející se elipsou, tzn. stanovit rychlostní pole a rozložení tlaku. Dále pak chceme stanovit přídavné silové účinky kapaliny působící na elipsu. Tyto výsledky získáme řešením Navierových-Stokesových rovnic metodou konečných prvků. Důraz je kladen na odvození numerického schématu v maticové formě vhodné pro numerickou implementaci. Časově závislá výpočetní síť je popsána pomocí Arbitrary Lagrangian-Eulerian (ALE) formulace. Pro obdržení relevantních výsledků je nutná stabilizace metody konečných prvků. Uvedené výsledky naznačují, že odvozená metoda je dostatečně přesná.

The thesis deals with a comparative analysis of strain of parts using finite element method (FEM) and measurement of the optical system Pontos. Part was used the reflector of Volkswagen Polo. The subject of comparing were the values of deviations optical shield of reflector which excitation random vibration described power spectral density. The thesis presented describes of experimental measurements to obtain the boundary conditions using optical systems. FEM analysis was performed using software ANSYS Workbench 12.

In this thesis, the author deals with structural design of lifting unit for the formula car. First, he searches in the currently used solutions, followed by selection of appropriate accessories, a preliminary analytical calculation and stress analysis model. In the last part, there is made economic and weight balance.

This work deals with the stress and strain analysis of the car front part of Škoda Octavia II. generation under impact loading using an explicit formulation of finite element method (FEM). The aim of this work is examination of resistance of the car front part under this impact loading and comparison of the data, which were get out of the FEM simulation of the car impact on the rigid wall with methods, which are used in forensic engineering. The comparison of the FEM simulation of the car impact on the rigid wall will be provided with the correlation method and with the method of energetic grid.

This master thesis describes the design and optimization of connecting rod motor racing car. At the beginning of the whole work is a 3D-model of rods, from which then the whole work is based. Then it analyzes the current model of stress and on the basis of the results are made structural changes to the solution of rods. Newly adapted connecting rod is again analyzed using FEM and newly obtained results are compared with results of the original model of connecting rods. The conclusion deals with sensitivity analysis of selected parameters of rods and their potential effect on the resulting changes in strength connecting rod .Then is an assessment of all results.

The main purpose of this diploma thesis is to design a swing axle of a truck for 4x4 chassis without wheel reduction gears. The study consist of two parts. The first part contains designs of main parts of the axle, mechanism of suspension and steering. The second part contains the gears housing stress analysis using the finite element method. The housing of gears is the arm of the swing axle, which is the main part of the chassis.

Thesis deals with the truck frame VARIANT 252. The main task is to analyze weighting states, setting the values for weigting states. Strength control of the frame by using the Finite Element Method (FEM). And each subsequent frame adjustments based on the results of FEM. Part of this thesis is also the drawing documentation provided a modified frame assembly and each modified components.

This diploma thesis deals with a frame design of a trailer for the transportation of building machinery. The thesis focuses mainly on the cross-check of strength, and also proposes suitable construction adjustments including their calculations in cases of stress. The strength and stability check is carried out by means of the finite element method. A drawing documentation of the trailer amendments is also included. This diploma thesis was created in collaboration with the company SVAN Chrudim s.r.o..
