Application of Modern Technologies to Concept of Production of Car Part Prototype
Bachorík, Patrik ; Jaroš, Aleš (referee) ; Sedlák, Josef (advisor)
The objective of my bachelor thesis is the design and manufacture of a prototype component for automobile industry. Specific designs and parameters of the prototype component were constructed in 3D parametric software Autodesk Inventor. Additive method Fused Deposition Modeling – a 3D printer uPrint was used for the production of the prototype component. A part of my work was the manufacturing of a silicone form with the use of a vacuum – moulding system. The purpose of this form was casting the required number of prototype components made of commercially available materials. Also, metrologic measuring of the pieces was carried out using 3D measuring machine with the aim of evaluation of manufacturing tolerance limits compared to the engineering drawing. The work was finished with technical and economic evaluation of the manufacture process of the prototype component with the subsequent analysis and overall assessment of the most convenient economic variant.

Design of injection molding cooling insert for manufacturing by Selective Laser Melting
Tekeľ, Richard Martin ; Vrána, Radek (referee) ; Koutný, Daniel (advisor)
This bachelor thesis focus on design of a cooling insert so the current mold cycle time will be reduced and it will be possible to manufacture the insert by SLM. Proposed modification includes 1 cooling line with non-circular cross section and disrupt empiric cooling line design recommendations. A research into differences of conventional and additive manufacturing of injection moulding inserts was conducted as well as into theoretical principles needed for a design of cooling lines and preview of similar solutions for the given task. After simulation of current state and obtaining a value of current cycle time, 3 different designs of cooling line were chosen and simulated in order to pick the most suitable one. This cooling design was afterwards modified to get conformal shape and lower distance from critical spot. The last part of thesis interpret the results from simulation of the final cooling line design and estimation of safety against fatigue failure.

Design and optimization of a low beam LED headlamp reflector
Varhaníková, Alžbeta ; Kapusta, Martin (referee) ; Novotný, Jan (advisor)
The diploma thesis deals with the optical design of low beam LED reflector. The thesis aims to optimize the existing low beam LED reflector with an emphasis on achieving a legal and homogeneous light distribution. The theoretical part contains the essay of light sources and optical systems used in headlights, as well as the description of the production technology of LED reflector for different polymeric materials. The experimental part presents a detailed methodology for the optical design of low beam LED reflector in the company software. The thesis also contains a description of the original low beam LED reflector and its problematic parts. The optimization of LED reflector was performed by changing its construction and by the replacement of the light source which increased the robustness of the whole system. In the conclusion, the optimization of LED reflector is evaluated by comparing final light distributions for individual LED reflectors.
