Driving dynamics of a tractor
Renza, Jaroslav ; Bradáč, Albert (referee) ; Panáček, Vladimír (advisor)
This thesis analyses driving dynamics of tractors and its dependence on their weight and age. In the beginning, brief history of tractor development and definition of basic concept of the tractor analysis is described. The thesis states procedures for obtaining magnitudes necessary for determining of driving dynamics. Experimental part describes the realized measurement on chosen sample of tractors and interprets measured values. Last part of the thesis contains evaluation of the measurement results.

Options for the Determination of the Influence of Electronic Stabilization Systems of the Chassis on the Driving Dynamics of a Vehicle
Bilík, Martin ; Vémola, Aleš (referee) ; Panáček, Vladimír (advisor)
This diploma thesis deals with the possibilities of determining the influence of electronic stability systems on the chassis of the vehicle driving dynamics. In the introductory section is made theoretical analysis of road vehicle dynamics. Further description is made of some stabilization systems and situations and how to solve them by using these systems. Chapter 6.2.1 describes the methodology of practical experiment, which can determine influence of the stability system of the vehicle chassis on driving dynamics. The next chapter describes an experiment conducted and interpreted the measured values. The penultimate chapter is a simulation of this experiment using simulation software Virtual Crash. The last chapter is an evaluation of the experiment and compares the results with simulation programs using the same input conditions. The conclusion summarizes the results of this work.

Influence of mass parameters on the vehicle driving dynamics
Dušek, Otakar ; Semela, Marek (referee) ; Panáček, Vladimír (advisor)
This diploma thesis deals with assessment of weight parameters impact on driving dynamics. History and basic categories of personal vehicles are described in the introductory part. Weight parameters and driving dynamics of personal vehicles are described in the next part. Methodology and results of realized driving tests (braking test, circular test and avoidance maneuver) are presented in the experimental part of this work. Simulation of realized driving tests that was made by simulation software Virtual Crash is devised in the penultimate chapter. Evaluation of results that were found out from realized and simulated driving tests is made in the last chapter. Achieved results are briefly summarized in conclusion.

Air Suspension Systems for Passenger Car Chassis
Mračnová, Michaela ; Zháňal, Lubor (referee) ; Fojtášek, Jan (advisor)
The main goal of this bachelor’s thesis is to characterise pneumatic suspension systems. The introductory chapter chronicles the historical development of these systems. The thesis includes the description of the main components of pneumatic suspension systems and explains theirs functions. Furthermore, it describes the principle of the system operation and derivation of the equations expressing characteristic system properties. The last chapter presents the benefits of systems in terms of driving dynamics and comfort.

Driving Dynamics of ATV vehicle 6x6
Juhász, Vojtěch ; Hejtmánek, Petr (referee) ; Blaťák, Ondřej (advisor)
This thesis focuses on the analysis of the driving dynamics and suspension of six-axle ATVs, which are increasingly used by armies for transporting cargo and assisting troops in various combat situations. Due to the unique design of the three-axle, equal wheelbase chassis, the vehicle's suspension behavior presents a significant challenge. The objective of this work is to build a multibody vehicle model using MSC Adams software, analyze the vehicle's handling characteristics in rough terrain and other driving maneuvers, and optimize the suspension and damping characteristics of each axle to improve the vehicle's handling characteristics. The results of this work will provide useful information for the design and development of more efficient and safer solutions for military and civilian applications.

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.
