Tyre Parameters Measurement
Pokorný, Pavel ; Vančura, Jan (referee) ; Blaťák, Ondřej (advisor)
It is the tyre that ensures the interaction between a wheel and road surface and it is the the tyre which also acts as a primary cushioning. Its construction, features and condition highly influence driving properties of a car and thus passenger safety as well. In motorsports the tyre is a key part of the vehicle and therefore it is necessary to make use of its complete potential for reaching the best results. The aim of this thesis is a device construction suitable for tyre parameter and their characteristics measurement. The next task is to design a measuring system for tyre pressure and temperature monitoring. With using of these devices a few real-tyre measurements and subsequent result evaluation will be done. The output of the thesis is an overview of construction details, overview of selected tyre parameters, design and drawing documentation of multipurpose measuring device and the results of my measurements.

Vliv zatížení a tlaku huštění pneumatik traktoru na utužení půdy
Minařík, Jiří
As farm tractors and field equipment become larger and heavier, there is a growing concern about soil compaction. Heavy equipment and tillage implements can cause damage to the soil structure. The soil structure is important, because it determines the ability of a soil to hold and conduct water, nutrients, and air. These properties are necessary for plant root activity. The basic connection between soil and machine are tyres. The choice of tyres in agriculture not only affects economy of soil operations and traffic, but it affects the soil structure too. The manufacturers of tyres and agricultural machines are developing new constructions, which has goal to decrease impact of heavy machinery on soil structure. Practical part of diploma thesis deals with the influence of load and inflation of tractor tyres on soil compaction. The results of experimental measurement confirmed negative influence of heavy tractor on soil structure.
