Drive systems wheeling mechanisms of mobile working machines
Voburka, Tomáš ; Hloušek, David (referee) ; Škopán, Miroslav (advisor)
ABSTRACT This bachelor thesis is describing current conceptual solutions of drive systems wheeling mechanisms of mobile working machines. It compares the different types of torque transmission from combustion engine to wheels in terms of efficiency, type of chassis and way of driving. It also focuses on the anticipated developmental trends of drive system.
The study of the behavior of track chassis using dynamic simulation
Hudec, Karel ; Kašpárek, Jaroslav (referee) ; Jonák, Martin (advisor)
This thesis deals with the study of the undercarriage, their components and organization. Further, this work is focused on selected types of machines with tracked chassis moving in forestry or for operation in forest ground. The second part of the thesis deals with the design of the tracked chassis for the forwarder and the subsequent verification of the functionalities by dynamic simulation.
Engine unit of the forestry forwarder
Koukal, Vojtěch ; Škopán, Miroslav (referee) ; Kašpárek, Jaroslav (advisor)
This bachelor’s thesis deals with theme of forest forwarders. In the first chapter there is research analysis of forestry forwarders in similar weight category. In the second chapter there is a calculated performance of the engine according to entered parameters. Based on the computed values the best engine unit is selected from the catalogues of manufacturers.
Central joint of forest forwarder LVS 511
Horký, David ; Kubín, Martin (referee) ; Pokorný, Přemysl (advisor)
This diploma thesis deals with stress analysis central joint of forest forwarder LVS 511. Stress analysis has been performed by finite element method (FEM) using the program NX I-deas. The diploma thesis was conducted in cooperation with the firm Strojírna novotný s.r.o.

Tracked chassis of a forwarder
Svoboda, Jan ; Pokorný, Jan (referee) ; Kašpárek, Jaroslav (advisor)
The thesis describes the design of a modular track undercarriage system for a forest utility vehicle called the forest forwarder. In the introduction there is a research study which reviews a variety of design options. The main part of the thesis describes the 3D model created in the Catia V5 programme. The model was subjected to an analysis of dynamic effects by simulated use of the track undercarriage system in the MSC Adams programme. A selected part of the undercarriage was analyzed by the finite element method in the Ansys Workbench programme. Drawing documentation of some of the components is included at the end of the thesis.
