SIMULATION OF THE SPRINKLING PROCESS WITH THE MACHINES OF FRONT ACTION WITH SECTOR NOZZLES

abstract 1001406040 issue 100 pp. 668 – 678 30.06.2014 ru 1036
The article deals with the methods of mathematical simulation of water distribution processes by the machine of unbroken front moving with deflector nozzles of sector influence. Mathematical simulation using lets choose the optimum labor and money expenditure. The nozzles work under low pressures, it results in power inputs reduction of liquid distribution process about the field along with more regular water distribution. The coefficient of water doze variation 1,71% under 7 m distance between the nozzles is got in the circulation example

STUDY OF MECHANICAL DAMAGE OF A CORN-COB UNDER ITS BRAKE-OFF IN A CORN-HARVESTER

abstract 0380804008 issue 38 pp. 127 – 137 29.04.2008 ru 4255
Brake-off of a corn-cob from a stem occurs in expense of a corn-cob blow and pedicle distention in modern husker-shredder corn-harvesters. Any mechanical impact is connected with deformation of a corn-cob. Forces destroying connection between grains with rod appear under its deformation. Condition under which mechanical damage of a corn-cob occurs is considered in the article.
