Gear trains in automotive electric drives
Vlaha, Ondřej ; Poulíček, Matěj (referee) ; Neuman, Ondřej (advisor)
This bachelor thesis deals with the research in field of gearbox applications in electric vehicles. It describes the classification of electric vehicles depending on the type of their powertrain. It also discusses the distribution of electric motor designs and analyses the parameters that affects the efficiency of the drive train. A numerical model of Tesla Model 3 was created in Matlab Simulink to illustrate the effect on powertrain efficiency when using single or dual speed transmission under different driving cycles.

Design of Driveline Placement System Units in Special Purpose Vehicle
Neuman, Ondřej ; Dundálek, Radim (referee) ; Ramík, Pavel (advisor)
This thesis is concerned with designing a powertrain mounting solution for high mobility off-road vehicle. It is created in collaboration with company Advanced Design Solution spol. s.r.o. The focus is to present a design process of a specific frame structure that supports the powertrain and isolates its vibrations. Majority of the thesis describes the use of finite element methods to assess static and cyclic loading of a welded structure. It also refers about selecting the correct vibration dumpers and covers manufacturing of the part.

Adaptive Damping for Trucks
Neuman, Ondřej ; Hejtmánek, Petr (referee) ; Blaťák, Ondřej (advisor)
This diploma thesis is concerned with designing a computational model of a commercial vehicle. In addition to that, a control algorithm for adaptive damping is presented. These two parts are connected into a closed loop and together they create an adaptive damping system. The primary task of the algorithm is to react on a vehicle load change. Vehicle model has the opportunity to create different driving scenarios, which are used to verify algorithm functionality. With the help of computational model and optimalization process, suitable damping characteristics are derived. An evaluation of vehicle comfort and driving safety is also presented.

Analysis of Business of Czech entrepreneurial entities in Italy on the example of selected companies
Brožová, Jana ; Zamykalová, Miroslava (advisor) ; Neuman, Ondřej (referee)
This thesis reports on the business of Czech entrepreneurial entities on the Italian market, in particular about their problems during penetration of this market and other specifics, which they daily have to deal with. The first chapter is devoted to the review of trade balance between Italy and the Czech Republic. It analyses the current state but also the recent development of the trade with goods and services, the commodity structure and the Italian investment environment. The second chapter deals with the most important export promotion organizations both in Italy and the Czech Republic. The third chapter analyzes the Italian market using the PEST analysis, which reviews the political-legal, economic, socio-cultural and technological influences on the market. The following three chapters describe the outcomes of a qualitative research conducted in three companies operating in different fields. The final chapter provides a comprehensive output in the form of a SWOT analysis of the Italian market and a set of several pieces of advice for current and future Czech exporters to the Italian market. The conclusion only recapitulates the previous chapters and summarizes the most important findings resulting from this thesis.
