Porovnání přenosu vertikálního zatížení od kolových a pásových sklízecích mlátiček
TKADLEC, Jakub
This diploma thesis deals with the comparison of the transfer of vertical load from wheel and belt combine harvesters to the soil. The load that the work deals with is for separate combine harvesters without an attached adapter. The aim of the work, was to create a database of vertical loads under the wheel or crawler chassis of combine harvesters, including the determination of the parameters of self-propelled combine harvesters. The calculated, measured and determined data were then included in graphs and tables with graphical representation of the load. The resulting data from the tables can also be used for computer simulations of soil loading under combine harvesters with wheeled or crawler chassis.

Porovnání přenosu vertikálního zatížení od kolových a pásových traktorů
ŠÁLENÝ, Miroslav
The work deals with the comparison of the transfer of vertical load from wheeled and crawler tractors to the ground. Only the tractor itself without the implement is considered. The aim of the work is to create a database of vertical load transfer under the individual axles of wheeled and crawler agricultural tractors and to collect other parameters of the measured equipment. The data will be able to be further used for computer simulation of soil compaction after the crossing of agricultural machinery.

Design of a mattrack unit of an RC model produced by the 3D printing
Mašek, Dominik ; Rekem, Jakub (referee) ; Otipka, Václav (advisor)
The focus of this bachelor thesis is 3D print and design of mattrack unit for the RC off-road car. In the first part there are description of 3D print technologies, materials for 3D print and evaluation which of this method is suitable for hobby printers. The second part is focused on technical solution and the design of mattrack unit, most of unit parts are made by 3D print. First step was choosing of type of construction which should be inspiration for this mattrack unit. It was necessary to choose suitable tolerance of holes and pins to get required deposition of printed parts. There was problem with an unstrung belt when bodies of guiding wheels rotated. This problem was solved by the mechanical limitation of rotate. The construction is described by the technical documentation which was created by the 3D model.

Tracked vehicle for working on a slope
Těšický, Petr ; Urbánek, Michal (referee) ; Kašpárek, Jaroslav (advisor)
This bachelor thesis deals with the conceptual design of a remotely controlled tracked vehicle for work on a slope. In the first part, a short research analysis of remotely controlled tracked vehicles is performed. During the design of the concept itself, dimensional, force and power calculations are performed. The design of some components is based on these calculations. Strength calculations for certain components are performed in the last part of this work. The result is a conceptual design of a remotely controlled tracked vehicle.

Conceptual design for stairs climbing
Choleva, Richard ; Szabari, Mikuláš (referee) ; Kočiš, Petr (advisor)
The bachelor's thesis focuses on the conceptual solution for the locomotor system of an industrial robot, which ensures movement and transport of the robot and alternatively, other manipulated objects up the stairs. The introduction of this work presents different types of industrial robots and locomotor systems used in practice. This is followed by an analysis of the problem and solutions proposal based on multicriteria analysis. Finally, the work focuses on the mechanical design of the locomotor system, its evaluation and discussion of the challenge.

Využití traktorů s pásovým podvozkem v podniku zemědělské prvovýroby
KRÁL, Martin
This diploma thesis deals with the use of powerful tractors with tracked chassis in agricultural primary production. For my work I chose Farma Pokorný Kmetiněves s. R. O., Which uses Challenger MT865E crawler tractor and BOTEP PLUS spol. s .r. o., which uses CASE IH STX 450 Quadtrac tracked tractors and CASE IH STX 480 Quadtrac. Literary review deals with the construction of wheeled and tracked bogies of tractors. The thesis describes the utilization of tracked tractors in given companies during the marketing year and analysis of the performance of individual tractors. The thesis is supplemented with characteristics of enterprises, description of technical parameters of individual machines and analysis of investment and operating costs.

The design of a mobile crawler undercarriage for transport mechine
Mareš, Michal ; Škopán, Miroslav (referee) ; Kašpárek, Jaroslav (advisor)
First part of this bachelor's thesis deals with the review of delta undercarriage for mobile crawlers with four delta crawler undercarriage. The text discuss the advantages and disadvantages of this approach. The second part of this work is aimed on the construction of such delta carriage with a maximum load of 5000 kg. The carriage is designed as modular to be able to be easily replaced. This basic concept was followed by precise mechanical design and the construction was supported by the basic mechanical computations of important parts. Detailed three-dimensional model of the undercarriage was performed in the Autodesk Inventor 2015 software.
