Computational Modeling of Dynamic Behaviour of Tractor
Hejčl, Pavel ; Řehák, Kamil (referee) ; Prokop, Aleš (advisor)
This work deals with the assessment of the effects of a rear-mounted mower on tractor dynamics. The first part summarizes knowledge of the used tractor suspension variants and their various modifications. Furthermore, the current possibilities for simulating the dynamics of tractors and the construction of the rear three-point hitch are described. The main part of the work is devoted to the assembly of the multibody model of the tractor with the rear-mounted mower. The correctness of the assembly of the virtual tractor prototype is verified by comparison with the technical experiment on the real tractor. The validated model is further used to analyse various well-defined steady-state and transient driving conditions typical of this set.

Influence of three-point hitch parameters on traction properties of tractors
Voburka, Tomáš ; Škopán, Miroslav (referee) ; Bauer, František (advisor)
The diploma thesis is focused on the development of a mathematical model of the tractor-tool set in the MSC Adams program enabling analysis of the influence of the position of the upper linkage of the three-point hitch on the load of the driving wheels during the system operation. The measured force effects are analysed with focus on the adhesion load of the drive wheels and the traction properties of the tractor. Based on the calculations made, it determines the optimal setting of the upper link of the hitch for the connected tool.
