| dc.description.abstract | Analizuojama varančiųjų ratų buksavimo ir traktoriaus traukos charakteristikų sąsaja. Varančiųjų ratų buksavimui įvertinti siūloma kaip lyginamuosius rodiklius imti svorio panaudojimo varančiųjų ratų sukibimui koeficientą bei priekabos ir traktoriaus masių santykio koeficientą. Apžvelgiamos ratų buksavimo priklausomybės nuo svorio panaudojimo ir priekabos bei traktoriaus masių santykio koeficientų lygtys. Pateiktos lygtys, analizuojančios svorio panaudojimo varančiųjų ratų sukibimui koeficiento priklausomybę nuo agregato riedėjimo pasipriešinimo koeficiento, darbinio greičio, įsibėgėjimo bei priekabos ir traktoriaus masių santykio. Taip pat pateikti eksperimentinių tyrimų rezultatai bandant agregatą ražienoje ir kultivuotame lauke, esant pastoviam greičiui ir įsibėgėjimo metu. Apžvelgiamos buksavimo lygtys ir jų priklausomybė nuo priekabos ir traktoriaus masių santykio bei traktoriaus su priekaba agregato svorio panaudojimo ratams sukti koeficiento | lt |
| dc.description.abstract | The article analyses the relation between the slippage of driving wheels and the traction characteristics of a tractor. The indicators for estimating wheel slippage are a coefficient of tractor weight force utilization for driving wheel grip and a coefficient of the ratio of trailer and tractor mass. The dependencies of wheel slippage on the weight utilization coefficient of tractors and the ratio of trailer and tractor mass are overviewed. The presented and carried out analysis of the equations of weight utilization coefficient φg determined its dependencies on rolling resistance coefficients f of a means of transport, working speed v and acceleration a on the mass ratio of a trailer and tractor mp/mt. The results of experimental research on acceleration and constant speed regimes in a cultivated soil and stubble are presented. The dependencies of slippage on the ratio of trailer and tractor mass and the weight utilisation coefficient of a tractor and trailer are viewed | en |
