Strain, stress and strength analysis of the truss construction.
Hladký, Maroš ; Horníková, Jana (referee) ; Vrbka, Jan (advisor)
The thesis is focused on strain, strength, and strain analysis of planar truss construction. The purpose of this work is to determine the load on each rod, and to assess the safety against limit states. After determining the primary characteristics, the structure will be modified and load and safety re-calculated. Depending on the outcome, the design will be changed again. Next, will be destined gravity affect on the design and impact of production inaccuracy. Deformation of structure will be calculated.

Strip rolling
Kornherr, Milan ; Suchánek, Miroslav (referee) ; Petruška, Jindřich (advisor)
This bachelor thesis focuses on theoretical analysis of the role of plastic deformation in the process of rolling strips. The work explains progress of stress waveform during straining and lightening. This work also focuses on computing of spring loading and bending moment due to specific curvature of strips. Report at the end of this work includes an illustrative example with executional program.

Deriving and Application of Analytical Design of Hammerspring in Firearms
Vobejda, Radek ; Polzer, Stanislav (referee) ; Slažanský, Martin (advisor)
The thesis deals with inference of analytic relations for calculation of pressure helical coil spring and considerates usage possibilities of simplified relations. In the thesis there is introduced analytic computation of slightly curvatured rod theory completed by finite element method calculations. The thesis describes two springs of firearm, which weren’t able to achieve required functionality. After this there was created a plan of concept particular spring on the base of derivated relations, which should be able to meet operative conditions.

The deformation necks and their use in forming technology
Grufík, Lubomír ; Štroner, Marek (referee) ; Peterková, Eva (advisor)
The project which was elaborated in bachelor education presents summary of deformation necks and their use in forming technology. Pursuant to of the literary pursuit a problem of deformation necks in forming technology there were formulated description of given methods, summary of methods spreading of deformation necks on the surface of half-finished products, their assets and use in practice. Then there are conspectus of computer simulation, which is used so to evaluation of deformation and transformation, its advantages and disadvantages in practice.

Static analysis of suspension bridge variants
Zavřelová, Michaela ; Martinásek, Josef (referee) ; Vlk, Zbyněk (advisor)
The bachelor's thesis deals with the static analysis of individual models of suspension footbridges. A manual calculation of the cable was processed. The actual position of the cable was determined by calculation. The manual calculation was compared with the RFEM calculation program. Furthermore, the models were loaded with manually calculated loads. The bachelor's thesis deals with the influence of pylon deflection on the global deformations of cable and bridge deck during individual load cases and combinations. For one of the models, the optimization of construction was processed.

Static analysis of steel footbridge
Mareková, Adela ; Martinásek, Josef (referee) ; Vlk, Zbyněk (advisor)
The subject of the bachelor thesis is static analysis of a steel footbridge. Two different models of this structure are created in RFEM 5.16 software. The first model consists only of the upper part of the structure, the second model includes also the bottom part – columns. The load is calculated manually and applied on both models in the same way. RFEM software was also used for performing the calculation. The results from models are compared between each other and ultimate limit state assessment is carried out.

CFD simulation of refrigerant flow inside the semihermetic compressor
Tuhovčák, Ján ; Knotek, Stanislav (referee) ; Katolický, Jaroslav (advisor)
The CFD simulation of cooling piston compressor Stream, manufactured by Emerson company, is the topic of this diploma thesis. Analysis of moving parts (piston, valves) and refrigerant or physical settings for simulation were based on experimental data provided by Emerson. The goal of the thesis is to test opportunities of Star-CCM+ in simulating the flow inside the compressor. In the end there will be a comparison of experimental data and results from the simulation. The thesis also contains a theoretical background of piston compressors and phenomenon following the operating compressor.

Static and modal analysis of construction
Krzywoň, Filip ; Nevařil, Aleš (referee) ; Vlk, Zbyněk (advisor)
The bachelor thesis compares the behavior of different models of concrete tower structures influenced by earthquake load. There were several models made in Scia Engineer software and also one model for each tower for manual analysis. The results of modal analysis were further used along with Eurocode 8: Design of structures for earthquake resistance. The deformed models were compared with each other.
