Stress, strength and strain analysis of the crane truss construction.
Nedělka, Pavel ; Borák, Libor (referee) ; Vrbka, Jan (advisor)
This bachelor thesis deals with stress, strength and strain analysis of the plane crane truss construction. The aim of this work is the calculation of forces for the simple frame with the help of joint equilibrium equations. These forces will be modified by further construction treatment. This treatment turns the simply frame into the hyperstatic system. The obtained values data are the input data for the design of geometry of particular bars. The unknown dimensions will be determined by two strenght limit states. These limits are: limit state of elasticity and limit state of stability. Then we will make the strain analysis. It will determine the displacement in the action of the force, the effect of actual clearance as well as the brace failury effect to the construction safety. Further will be determined the influence of the weight of the construction to the strenght.

Semi-trailer for a vehicle transport
Švec, Milan ; Robotka, Tomáš (referee) ; Kašpárek, Jaroslav (advisor)
The aim of the diploma thesis is the construction design of a semi – trailer for the purpose of road – based vehicle transportation. The construction design is complaint to the applicable legislative requirements for the corresponding trailer category. The main part of the thesis focuses on strength analysis of a semi – trailer frame using finite element method. Based on strength analysis of the semi – trailer frame, the original frame is adjusted and further optimized through subsequent analyses. The thesis additionally contains the drawing documentation.

Optimization of an aircraft wing rib
Kopřiva, Lubomír ; Suchánek, Miroslav (referee) ; Petruška, Jindřich (advisor)
Topology optimization is a method providing new direction in designing of a technical objects. The aim of topology optimization is to find optimal distribution of material in design space. This diploma thesis is focused on optimization of aircraft wing rib num.6 of the airplane EV-55 using a software HW/Optistruct 7.0 implemented in a software package HyperWorks 7.0. The optimization of the rib was calculated under four different load cases. Resulting shapes of the rib were then tested by strenght calculations in software ANSYS 10.0. Finally, the obtained data of weights of optimized ribs were compared with the weight of the original rib.

Stiffness estimation at the machining head and the strength analysis of the moving parts of the machining center MCV 1220.
Zbožínek, Martin ; Houfek, Martin (referee) ; Vrbka, Jan (advisor)
Main objective of the work was to estimate the possibilities and the limits of elementary stress and strain analysis of the construction. At the beginning it was necessary to simplify the problem to the 1-D bar problem. The calculation was performed for three typical loading cases, namely for the middle and the border position of the machining head. The contact forces and momentums and the displacements at the machining head have been calculated. The obtained results were then used for the stiffness evaluation of the construction at the machining head. The strength analysis of the moving parts of the machinig center has been done, too. Modern software products (Autodesk Inventor, ProENGINEER, ANSYS Workbench, Maple, Mathcad, etc.) were used for the calculation. The results were compared with The Finite Element Method results.

Motor-driven roller conveyor
Seďa, Marek ; Kašpárek, Jaroslav (referee) ; Pokorný, Přemysl (advisor)
Baccalaureate work deal with conceptual proposal powered motor-driven roller conveyor longitude 15 m, that the will transport cast given to proportions for either seats overleaf. Work is bent on calculation principal dimensions, solidity verification and generally general proposal constructional solving conveyor. Is free time type roller for transport casts saved on pallets, drive track, which will elect electric motor with gear - box. Last but not least also chain gearthat the to us will serve as driving element rollers. Baccalaureate work would had contribute by firms, companies and subjects, that the derive benefit from roller conveyor for transportation materials. She should enrich constructional possibilities solving these arrangements.
