Proposal of the Plastic Overload Clutch
Ujčík, Martin ; Mrázek, Dušan (referee) ; Samek, František (advisor)
The bachelor thesis describes the proposal of the geometrical change on the sliding holder which is ensuring adjusting of the headlamp in to the correct position. It means a change of geometrical concept. Proposed geometry overtakes the security function of the overload clutch witch ensured in current solution additional part. Proposal was created in CAD System Catia. Function of the solution was tested with finite element method in SimDesigner program and with the evaluation of measuring of prototype part.

New Solutions for Settings Car Headlamps
Glatter, Willi ; Straka, Ivo (referee) ; Kalivoda, Milan (advisor)
The aim is to develop new adjusting element. There were three versions of engineering design suggested, which were consequently simulated for various materials. Optimal material was chosen and came up to production suggested variants. These variants were consequently implemented to the headlamp and were consequently measured and tested. During measuring was under consideration change of CutOff line position after heat imunity and vibration tests. Result is selection only one material and only one engineering design of adjusting element solution, which warrants easy and fast assembly and confidential adjusting of reflector, for standardization and implementation to recently develop headlamps.

Modern Systems of Vehicle Lighting
Špaček, Ladislav ; Huzlík, Rostislav (referee) ; Hájek, Vítězslav (advisor)
A vehicle lighting is a basic component of active safeness, which, as an integral part of any vehicle, contributes to road traffic safety increase. From the very beginning, the car electrotechnincs has been engaged in the car lighting and visibility improvment for worse driving conditions, e.g. fog, rain, night ride etc. Thanks to new car lighting systems, such as adaptive headlights, LED based light sources and night vision systems, road traffic became much safer than ever before.

Analysis of the effect of damping on the magnitude of the response during dynamic headlamp excitation
Lukáš, Jan ; Biskup, Martin (referee) ; Vosynek, Petr (advisor)
The aim of the submitted diploma thesis is the magnitude determination of the headlamp response to the dynamic excitation. Currently it is necessary to measure this response, because it is one of the assessed criteria of quality of the headlamp. When comparing results of the experimental measurement and the computational modelling, a good consensus of resonant frequencies is observed, but there are significant differences in acceleration amplitudes. The cause of this is the variable damping value. The theoretical part of the thesis deals with polymeric materials, basics of oscillation and damping. It serves to understand the mechanisms, which influence the results of the experimental measurement. The practical part is dedicated to the procedure of the computational modelling and the experimental measurement implementation. The analysis of the experimental measurement results leads to an ascertainment of nonlinearities, which influence the headlamp behaviour. The results of a sensitivity analysis of the computational modelling are used to create curves, on the basis of which the damping is estimated. The inclusion of the estimated damping into computational modelling leads to reduction of the compared differences of the acceleration amplitudes. The conclusion of the thesis contains the recommendation for the damping determination during the computational modelling of the headlamp.

Placement Optimization of Projector Lens
Bezděk, Matěj ; Važík, Jiří (referee) ; Novotný, Pavel (advisor)
This diploma thesis deals with the creation of engineering design of holder of projector lens. The thesis is created in cooperation with department of development in Varroc Lighting Systems, s.r.o. Initial part provides a brief description of the development of lighting technology used in car´s headlamps. The following part describes solutions currently used in clamping the lens in holder. The main part of the thesis focuses on the design of holder of projector lens itself. Projector lenses testing provide critical values of cohesive failure of the lens material, which cannot be exceed during the process of lens fitting and its subsequent clamping. In the final part the engineering design is verified and optimized using finite element analysis.
