MATHEMATICAL MODEL OF A MACHINE AND TRACTOR UNIT WITH EDM IN TRANSMISSION OF A TRACTOR
DescriptionThe developed mathematical model of the machine and tractor unit with the elastically damping mechanism in transmission of a tractor is given in the article. The analysis of mathematical model of the arable unit on the basis of a tractor with EDM in transmission showed that the MTU mathematical model can be considered as working

REGULARITIES OF DEFLECTION IN THE DIAGONAL AND RADIAL TIRES OF THE GRAIN COMBINE PROPULSIONS
DescriptionThe aim of the study is to investigate the regularities of deflection in the diagonal and radial tires for the grain combine propulsions of high productivity. The research method is experimental. The "tire tester" and specially designed devices for revealing the deflections of the inner and outer tube relative to the rim in the circumferential and radial directions have been used. The outcome indices of the pneumatic-tired wheel are determined with the tire capability to deflect so, that at low - hysteresis losses in the rubber-cord casing and its acceptable tensions, based on a resource, the largest area of contact with supporting base would be created. This circumstance acquires the particular significance developing tires for grain combines of high performance, the deflection regularities of which are poorly studied at present. The analysis of experimental studies showed the feasibility of using the grain combine propulsions instead of the diagonal radial tires of the same size. The resistance to rolling of radial tires 30.5 R-32 is lower than in diagonal tires 30.5 L-32, and the developed contact area due to the increase of length is higher, which reduces sealing effect on the soil
