Měření vertikálního zatížení pod jednotlivými nápravami traktorů

The aim of this bachelor thesis is to create a database of parameters to enable computer modeling and simulation of soil compaction resulting from vertical loads under individual tractor axles. The tractors used for obtaining these parameters were selected in the Author's place of residence and close surroundings. The theoretical part provides tractor comparison by purpose, chassis, frame, fuel, and gearbox. Furthemore the comparison of different types of tyres is included as these affect tractor's weight distribution in relation to the ground. In the practical part, the Author gathered parameters required for the database from a total of 20 tractors, these included manufacturers such as Massey Ferguson, Stey, John Deere, Zetor and New Holland. Some parameters included the vertical loads for front and rear axles, which was then calculated as a percentage of the total load, tractor dimensions, tire sizes and manufacturer, power output, tank volume and year of manufacture
