Commercial vehicles powertrains design
Krupa, Lukáš ; Suchý, Jan (referee) ; Fojtášek, Jan (advisor)
In this work there are described parts of powertrain of currently used commercial vehicles and their configurations depending on the conception and purpose of vehicle. Individual parts of powertrain are described in terms of both design solutions and operating principle. The work is of the retrieval of character and serves as a source of information about the issue. It can be used for example as a teaching tool for getting deeper knowledge about the topic of powertrains of commercial vehicles.

Photovoltaic System for Recharging Electric Vehicle
Krúpa, Lukáš ; Bátora, Branislav (referee) ; Baxant, Petr (advisor)
This master thesis deals with use grid-off photovoltaic system for recharging electric vehicle. First is explained the principle of converting solar energy into electric energy and theoretically describes the components of the system. Furthermore, is presented a real application of the photovoltaic power plants in the world for recharging electric vehicles but also for other uses. The next section theoretically describes the grid-off system how it shout look like in real and there are presented the possibilities of choice of components. The main part is the actual construction of the grid-off system for recharging electric vehicle and measurement. The conclusion of this thesis is made up for the expected economic recovery of the entire system.

Computational simulation of vibrations of rubber damper
Krupa, Lukáš ; Návrat, Tomáš (referee) ; Burša, Jiří (advisor)
This thesis deals with computational modelling of rubber damper using Finite element method (FEM). This thesis includes experimental measurement of material properties of rubber subjected to static and dynamic loading and their implementation into viscoelastic and hyperelastic material models with respect to given task. Dependance of dynamic stiffness on loading frequency obtained from the simulation is validated with experimental measurement. In the end the difference between results is investigated and possible causes of that are introduced.

Possibilities of using small hydroelectric power plant in the wastewater treatment plant
Krúpa, Lukáš ; Haluza, Miroslav (referee) ; Pěcha, Jiří (advisor)
This bachelor’s thesis focuses on the possibilities of using small hydroelectric power plant in wastewater treatment plant. The first part is theoretical and describes the theory of wastewater treatment plants, small hydro power plants, turbines and generators. The seconds part focus is to describe the design of small hydro power plant. It begins with description of location then continues with calculation of Banki turbine and ends with generator selection. The last part deals with an economic evaluation, which includes estimating of the investment costs, the price of saved electricity and determining the estimated return on investment. In conclusion the thesis compares the ways of using the produced electricity.
