Abstract:
Svakodnevno povećanje stupnja kvalitete u izradi ili modifi kaciji dijelova, te povećanje obima elektroničkih dijelova,ima veliki utjecaj i na automobilsku industriju, kao jednu od ekonomski važnijih industrija. Navedeno se možepotvrditi, ako se izvrši detaljan pregled vozila proizvedenih 1990.-ih godina i uradi usporedba sa vozilima koja su danasu proizvodnom programu. Ova činjenica običnog čovjeka, kao krajnjeg korisnika tih vozila, ugodno iznenađuje, pa sejednostavno zapita na koje sve sitnice misle projektanti i u kojem stupnju žele svaki pojedini sklop dovesti do granica idealnog,kako bi prosječan vozač mogao, sa što manje napora, upravljati vozilom. U radu se pravi analiza sadašnjeg stanjana koje se vrši vrednovanje konstrukcija vozila, odnosno prije i nakon nezgode, te se na temelju toga sačinjava prijedlogkoji je rezultat provedenog vrednovanja sa ciljem dobivanja što kvalitetnijeg proračunskog prikaza i dobivanja što točnijevrijednosti vozila nakon deformacije, odnosno same konstrukcija vozila.

Abstract:
Cilj ovog rada je, na Osnovnom sudu u Mostaru dokazati pogrešnu tvrdnju koju je prometna policija u svom zapisniku na mjestu prometne nezgode istu okarakterizirala kao namještenu bez ikakvih materijalnih dokaza. Za učesnike uprometnoj nezgodi pored prekršajne je podignut i krivični postupak. Insinuacija za namještenu nezgodu bila je u nesrazmjeri oštećenja na prednjem i stražnjem dijelu vozila. Ovim radom je dokazano u kom odnosu stoje deformacije na vozilus obzirom na vrijednost otpornog momenta poprečnog presjeka prednjeg i stražnjeg dijela vozila.

The Diploma thesis deals with segmentation of characteristic car damages, which arise during car crushes with ambient infrastructure of roads with concrete specialization to car crushes with trees and road culverts. According to chosen clash configurations there were characterized appropriate damages of front part of the car with usage of materials from real accidents. Level of damage is described according to location of the main point of impact and a speed during clash. The thesis provides summary of possible level of damage single parts of the car with focusing to front part and it gives opportunity comparison to detected damages during real car crushes with car damages made during manipulated harmful events.

Abstract:
Several types of discrepancies have been examined between CFD simulations, wind tunnel measurements and real world conditions. The results of different wheel rotation methods show that while stationary approaches can often substitute real unsteady wheel rotation, they can also be very sensitive to the exact angular positioning of wheel rims. Using both measured and computed flow fields, the lower part of wheel wake was identified as a key area, showing differences between rotation methods and sources of simulation errors in general. It was also shown that the level of detail in tyre geometry and its deformation near contact patch do not have a large impact on accuracy. Due to the absence of tyre rotation, the tyre sidewall was identified as an important place of flow separation with large effect on flow field and forces. Angle of attack study confirmed that assessing purely straight-line drag causes its under prediction compared to real-world values. This judgement would however benefit from obtaining data in more adverse conditions compared to those currently available. Finally, tyre radial expansion was investigated, causing a drop in drag with increasing vehicle velocity and altering the flow around the rear bodywork. Ignoring this effect can therefore negatively influence the aerodynamic development of a vehicle.

Abstract:
This diploma thesis deals with a comprehensive analysis of the photographic documentation of vehicle damage in traffic accidents. A systematic overview of the current documentation and included inspection is carried out in the analysis. Police records are compared with records made during the crash tests. Further, the documentation in this thesis is divided into two groups of conflicts. The representative of the accidents are described in detail and then evaluated. Similarly, this procedure is practiced on other car accident that reflect the mutual deformation. The result of this thesis is to determine the optimal location of the lens for the acquisition of documentation and establishing a baseline number of photos to document damage to the vehicle after the traffic accident.

Thesis deals with the compatibility of vehicles in a frontal collision. The first section discusses about compatibility from different views. There are the physical processes used in the mechanics of impact. The second part is focused on solving the compatibility of vehicles in a frontal collision by crash analysis using the finite element method. Firstly there are described collisions of vehicles from different vehicle classes (small cars, lower middle class, Pick up / SUV) into the fixed barrier by the US NCAP. Furthermore there are simulated head-on collisions of vehicles from different vehicle classes. In the end there is shown the possibility of using data from crash tests to determine the EES.

Abstract:
The presented work analyses the methodology and approach of the legislation. It presents in the press presented results of numerical modelling of the impact of vehicles crashed into barriers that are being solved in the Czech Republic and worldwide. It presents a recommendation of a methodology for assessing crash barriers. The methodology follows the basic principles used in the TP 101 and EN 1991-1-1. The kinetic energy of the vehicle at the moment of impact is replaced with substitute static force, whose effects are comparable with those of a vehicle collision. The supporting structure of crash barriers is implemented in compliance with means of statics. The calculation includes the vehicle deformation, which represents the real distribution of the energy absorbed by the deformation of the vehicle and the energy that crash barriers need to absorb. The proposed methods allow to take into account non-linear behaviour of the structure both in terms of geometry and in terms of material nonlinearity. The work also deals with the interpretation of various types of support structures in the computational model. A specific case is used for a demonstration of a way of modelling the elastic supporting column of crash barriers in the soil, or modelling the friction of a loose concrete block over the surface. To ensure the proper position of interconnected loose blocks corresponding to the reality, a method of modelling the place of a possible contact of the breakthrough is drafted. A significant contribution to the more accurate calculation is achieved by sequential increase of the load on the construction by using load increment and measurement of energy increases absorbed by the deformation in each step. The presented methodology is an effective tool to assess crash barriers. For the application of this tool, using common resources and facilities available to almost every designer dealing with statics of structures is sufficient. In conclusion, the knowledge obtained fr
