Analýza silových účinků pluhů na výstupní parametry orebních souprav
 Slimařík, Dušan
The aim of this thesis is force effect analysis of ploughing rigs. MSC Adams software was used for mathematical-physical model drafting and subsequent evaluation of measured data from tensometrical load sensing. Designed model was utilized for force reactions calculations under the driving wheels of a tractor using analysis of spatial system of forces of tractors three point hitch. Field measurement data and data from MSC Adams software were tabular and graphically processed. Dependencies between plough and tractor connection setting and output performance of ploughing rigs were clarified. Results from experimental measurement with fully-mounted plough point out on the utilization of longitudinal and lateral position of ploughs CG for reducing of difference in load between furrow and land wheel with properly adjusted connection between plough and tractor. A result from experimental measurement with semi-mounted plough confirms the fact of significant difference in vertical load between rear axle wheels. This negative phenomenon could be eliminated with usage of traction cylinder localized in construction of semi-mounted ploughs over the horizontal joint. Correct adjustment of tractors three point hitch in case of fully-mounted ploughs and utilization of traction cylinder in case of semi-mounted ploughs have got positive influence on fuel consumption and field performance of ploughing rigs.
