Analysis of extensions for mounting a harvester head on an excavator
Popela, Dominik ; Struhal, Vít (referee) ; Mergl, Václav (advisor)
The introduction of the thesis deals with a complete research of individual components that need to be mounted on an excavator to make it possible to use it for forest harvest. An integral part of the research is a detailed market research, thanks to which various designs of manufactured attachments were analyzed. The research part is followed by a description of the selected components of the assembly, which form an excavator attachment for its use in forest harvest. The following chapter already describes the author's own designs of the extensions design in three variants. The key part of the thesis is dedicated to dynamic simulation of the harvesting process and strength simulations of the designed extensions. Using dynamic simulation, the course of the force effects acting on the attachment pin, which arise during the process of felling a tree, was determined. The maximum force effects were determined from the results of the dynamic simulation, which were then applied in the strength analysis. The finite element method was chosen for the calculation of the strength analysis. The final form of the individual design variants of the extensions arose from the performed strength analyses. The conclusion of the thesis evaluates the achieved results and a detailed comparison of the created design variants of the extensions.

Additional working equipment and tools for earth-moving machinery
Švrček, Jakub ; Hloušek, David (referee) ; Škopán, Miroslav (advisor)
Bachelor thesis deals with explore attachments for earth-moving machinery produced in present time, especially for loaders and excavators. Bachelor thesis has critical research form and his task is to create inventory of tools and equipment, which is used for expanding ver-sality. Next task of bachelor thesis is referring to basic construction principles, typical oper-ating properties and ways of future development. In thesis are described equipment intend-ed for some earthworks, especially earth-drills, trenchers and backhoe attachment. In thesis are described some additional equipment for maintenance and repairs roads, which covers equipment like plate compactors, roller compactors and snow blower and snow blades.

Design of mini backhoe
Vorlíček, Vít ; Kašpárek, Jaroslav (referee) ; Škopán, Miroslav (advisor)
The aim of the bachelor thesis is to design a small tractor backhoe and aggregate it into a three-point suspension system with a maximum tearing force of at least 20 KN. This thesis is divided into six chapters and it deals with the division of excavator equipment, parts of excavation and analysis of competition, alternatives of design solution, design of own concept, functional calculations and strength calculations.
