Improvement of the method of calculation of pressure of combine harvester propulsion on soil

BACKGROUND: Currently there is no simple and reliable algorithm of assessment pressure on soil for the harvesters presented market. Therefore, analysis methods in active standards used calculation propulsion as well development simplified acceptable manufacturing specialists method are relevant.
 AIMS: Simplification force action to wheels during operation cycle from beginning until end combine harvester tanker filling.
 METHODS: The values wheel filling that allows exclusion weighing a with filled proposed.
 RESULTS: As result studies, complex sequential actions determining load machinery soil, including weight center mass coordinates grain inside following normal forces caused by summarized (with an empty tanker) considering location their centers mass, was justified.
 CONCLUSIONS: new application makes it possible define maximal range this indicators grain. In case, at special area hard surface procedures loading, unloading weighing, excluded. result, ability quick comparison criterion level impact respect operational ensured, which study subject. Thus, order solve given task, suffices use results harvesting tanker, available open sources, followed according proposed algorithm. Minimal divergence (less than 2%) calculated measured platform scales found.
