Construction of equipment for thin walled L-profiles instability testing
Polčák, Marek ; Vaněk, František (referee) ; Horák, Marek (advisor)
Bachelor’s thesis deals with the loss of stability of axially loaded thin-walled aluminium profi-les, which make up an important part in the aircraft structures. The loss of their stability is tes-ted by the compression test, which is used to determine the buckling load. Compression test may be influenced by many factors, which are related to the fixing to the testing machine. The aim of the thesis is to design a fixture, which would fix a specimen to the testing machine and improve the results of the test.

Design of a Robotic Cell for a Steel Frame Welding
Kysela, Martin ; Kubela, Tomáš (referee) ; Pochylý, Aleš (advisor)
The aim of this diploma thesis is to design a cell for robotic arc welding of steel frame. Three possible solutions are provided and one of them is to be chosen to work out. Construction designs of fixture, machine guarding and material racks were created and devices and components required for cell functionality were chosen. All of that with regard to the safety of workplace operators.The result is 3D model of welding cell, it´s implementation and virtual commissioning in the simulation software Process simulate. We will verify the weldability of assigned part, find out the production cycle, eliminate error and lastly the technical and economic evaluation will be work out.

Rationalization of segment production of the forming tool
Pilař, Radek ; Kalivoda, Milan (referee) ; Osička, Karel (advisor)
Master thesis is focused on the rationalization of production of the forming segment, which is manufactured by company OMNI-X CZ. Familiarization with the product „forming segment“, with issue of production with possibility improvment. The work is also focused on the preparation of the clamping fixture, which should improve the production conditions. The main point of the work include the calculation of cutting forces, clamping forces of the fixture, verification of safety process with economic evaluation. The aim of this master thesis is to indicate the possible direction of the rationalization of the manufacturing of the shaping segments for OMNI-X CZ.

Optimization of Vehicle Semi-Trailing Arm Suspension
Vávra, Radek ; Blaťák, Ondřej (referee) ; Hejtmánek, Petr (advisor)
This thesis is concerned with the design of Škoda 130 RS rear Semi-Trailing Arm Suspension and fixtures on the body. The main requirement of this thesis is to reduce weight of suspension. It is carried out the kinematic analysis and optimization of the kinematic. The construction part of this thesis provides a design of suspension based on the analysis of forces acting on the car wheel. Last part of the thesis includes of new rear suspension stress analysis.

Design of a simulator module for analysis of friction and wear of teeth during cleaning
Snopek, Lukáš ; Streďanská, Alexandra (referee) ; Vrbka, Martin (advisor)
This thesis focuses on the design of a module for the tribological simulator Bruker UMT TriboLab, which will be used in research in the field of analysis of wear of hard dental tissues and filling materials due to tooth cleaning. The aim of this work was the design of experimental conditions, module construction, creation of drawing documentation, production and subsequent implementation of a validation experiment. The conditions of the experiment were determined on the basis of research and to create an optimal design solution, prototypes were continuously produced using the 3D printing method. Finally, two toothbrush fixtures and two dental filling sample fixtures were made based on the drawing documentation. Subsequent assembly of the fixtures and the implementation of the experiment on the tribometer verified their functionality, which makes it possible to declare all the goals successfully met. Now these fixtures will be part of several research tasks in the field of oral biotribology.

Trends in development of cutting tools clamping
Servus, Tomáš ; Zemčík, Oskar (referee) ; Osička, Karel (advisor)
This master’s thesis defines and closely specifies actual trends in clamping systems for shank tools, especially used for milling and drilling operations. The project describes possibilities of application of clamping systems for shank tools for particular types of machining and briefly defines their principles. Experimental part is focused on material analyse of hydraulic and thermal clamping system. Comparing of clamping systems in term of their technical properties and their initial costs is included in technical and economical conclusion.

Design of stand for torque measurement
Zerzánek, Ondřej ; Zeizinger, Lukáš (referee) ; Čípek, Pavel (advisor)
This bachelor thesis deals with design of stand for torque measurements and additional fixtures. Issue is realized by aluminium profile systems and manufactured or purchased parts. Solution takes in account limited manufacturing options. Final part of this thesis is 3D model and critical evaluation of design. This thesis is useful example of how to create torque stand instead purchasing expensive commercially available stand.
