The effect of manufacturing inaccuracies on the final light intensity distribution of an automotive headlamp
Březnová, Tereza ; Lysa, Bohuslav (referee) ; Novotný, Jan (advisor)
The thesis deals with the issue of headlamp defects arising during production and their impact on the resulting light trail. The thesis describes and analyses defects arising during individual correction loops. Their analysis was carried out in order to provide measures for other projects. The main defects that have been assessed include the position of the light source, the quality of the optical surfaces and the associated quality of the plating, inaccuracies of the optical surfaces, dimensional variations due to installation technology and defects on the cover glass. The proposed measures concern the pressing tool, accuracy of machining and surface polishing. The thesis also includes designing solutions for quick identification of the surface quality of the cover glass by remote projection. Individual defects were described by their originators, their seriousness and their reparability. Based on this information, recommendations for production are proposed.

Replacement of headlamp parts screw fixation by a plastic nail
Lysa, Bohuslav ; Píška, Miroslav (referee) ; Polzer, Aleš (advisor)
The master thesis covers several issues linked to a substitution of headlamp screw fixation by a plastic nail. The thesis includes an analysis of the headlamp technology, including description of the prescribed durability tests. On the basis of the analysis some new designs of plastic nails are proposed, consistent with characteristics of plastic materials. Selected outcomes of the analysis have been tested as prototypes and verified with Finite Elements Method in SimDesigner including 3D modeling capabilities provided by the Catia V5. The feasibility study regarding a casting form of the new design of plastic nails and technical economic valuation for contingent assembly mounting is included in the thesis.

A New Design for Sealing Headlamp Adjusting Screws
Lysa, Bohuslav ; Mrázek, Dušan (referee) ; Samek, František (advisor)
The bachelor thesis covers several issues connected with the sealing of headlamp adjusting screw. The thesis includes analysis of the O-ring fastening and analysis of the fixation adjusting screw in functional position. On the basis of the analyses a new design of O-ring fastening, a new design of the adjusting screw fixation are proposed. Finite Elements Method in SimDesigner software using 3D modeling capabilities provided by Catia V5 were used for calculations and simulations in selected parts of the analysis. The feasibility study regarding adjustments of the existing casting form of the adjusting screw is included in the thesis.
