Scooter powered by cordless drill
Šimo, Samuel ; Böhm, Michael (referee) ; Štětina, Josef (advisor)
This bachelor thesis analyses the problematics of scooters with additional driving force and new opportunities in usage of unconventional methods of propulsion. The first part describes history and early development of prototypes. Then it reports on current legislative regulations in road traffic. The second part comments on design procedure of cordless drill - powered scooter with detailed description of used components.

Wood processing processes and problems of production technology of semi-finished products
Šimo, Samuel ; Osička, Karel (referee) ; Chladil, Josef (advisor)
The diploma thesis is focused on the optimization of a new production line of the woodprocessing factory DCP Timber. In the first part, the work approaches wood in terms of itsinternal structure and its physical and mechanical properties. The second part is focused on themost common methods of cutting the wood material. The third part describes the technology ofconvection drying of wood and the impact of this drying on the resulting quality of woodensemi-finished products. The practical part of the thesis is the solution to the inefficientproduction of the machine of the circular saw, which is an important part of the production line.There is a comparison of different cutting tools and their effect on dimensional tolerances. Inthe next point, thanks to mathematical models, the parameters of maximum feed speed andpower of the electric motor of the spreading saw are determined. Finally, a technical andeconomic evaluation is developed where the payback period is calculated in the case ofinvestment in a power unit with higher performance.
