The utilization of reverse engineering in computation of vehicle aerodynamics
Rozsíval, Jan ; Forman, Matěj (referee) ; Porteš, Petr (advisor)
The vehicle body was measured by using ATOS 3D scanner. Measured data from the ATOS 3D scanner were applied to make a 3D model of vehicle body and to make a 3D model of whole vehicle by using computer program Pro/ENGINEER. The model of vehicle was made with a view for future use of CAD model. Surface of the vehicle model was used for computation of vehicle aerodynamics – aerodynamic static pressure distribution by using CFD software Star-CCM+.

Application of modern methods for production of mobile phone storage stand
Tesař, Jaroslav ; Nejedlý, Jindřich (referee) ; Sedlák, Josef (advisor)
The thesis was made as a bachelor’s project on Faculty of Mechanical Engineering, Brno University of Technology. In the theoretical part methods of Reverse Engineering were described. The principle of the following technology, the Rapid Prototyping, was also explained and the summary of advantages and disadvantages and use in technical practice for the most important methods was made. In the experimental part of the thesis the modern methods were applied for manufacturing a cell phone holder. By this the possibility of these technologies to work with complexly shaped models was verified. The casting to a silicon form was used as the alternative method of manufacturing. The summary of possibilities of manufacturing with these technologies and technical and economical evaluation were made in the end of the thesis.

Application of modern technologies for the production of the release mechanism of a car door
Hruška, Lukáš ; Dvořáček, Jan (referee) ; Sedlák, Josef (advisor)
The Bachelor`s work concerns the production of door ulocking mechanism for a passanger car Renault Megane. From the viewpoint of function and the necessity to keep the exact dimensions of chosen parts were the data for the production obtained by digitalization of a real product. The digitalization was carried out by the contactless optical 3D scanner of GOM mbH company, specifically the developmental series ATOS II Triple Scan. The pin`s data were obtained from parametrical program Autodesk Inventor 2011. For the production of Master models the additive technology Rapid Prototyping, method Fused Deposition Modeling, was used. Master model of the handle was used for the production od solicon mould, that was used for casting of required number of handles from resin. The end of the work deals with a technical and economical assessment of the production. A part of the work is also a summary of the most used methods of Rapid Prototyping and Reversible Engineering.
