Vliv parametrů pozemku na nasazení techniky
Šmíd, Zdeněk
Data management helps farmers to better organize their work and plan the movement of machinery in the field, depending on legal or geographical conditions. Guidance, data collection and software used for optimization, as well as its functions, possibilities and working environment are described in the theoretical part of the work. Furthermore, the methodology describes the methods of measurement and evaluation. The own work verifies the effect of optimization on the operation in the field. The verification was realized by collecting data of the movement in the field and their subsequent evaluation. At the end of the work is the evaluation of the measurement results and whether the optimization of the movement of machines on the land makes sense. By processing the results, it was found that the optimization of guidance lines around the land reduced the time required for turning by up to 21 % and thus the consumption of diesel by 6,5 %.

Možnosti využití automatizačních prvků sklízecích strojů
Šmíd, Zdeněk
The bachelor thesis deals with the possibilities of using automation elements on combine harvesters and forage harvesters. The literary review presents the basic elements of automation in general view. The next part deals with individual functional elements of automation on combine harvesters and forage harvesters and their possibilities of use. This part also includes practical knowledge of harvesting technology. At the end of the thesis there is a summary of usage and influence of automation on work efficiency.

The solution of abrasion Zr bands : contract number-771122
Svoboda, Jaroslav ; Štěpánek, I. ; Šmíd, Zdeněk ; Klášterka, Petr
The aim of works was experimentaly stated the value abrasion constant C in the Archard relation for Zr material who create coverning fuel thin stick in fuel assembly of the nuclear reactor. It was find that the abrasion mechanizmus depend on the amplitudesize and the frequency oscilation.By the small oscilations amplitude and high frequency is the abrasion smaller as by the low frequency and a big amplitude. The mechanizm of abrasion is another in both cases.
