One of the advantages plowing is ability plow to hide weed seeds deep into soil. The depth embankment exceeds 10-12 cm, from there weeds can not rise surface They perish halfway. But for this, it necessary wrap soil layers at an angle close 180 °. Modern ploughs turn more than 135 °, therefore required be equipped with additional working elements. aim study create adaptation expand furrow before laying next layer. In a wide furrow, formation will completely tip, previous layer interfere it....
Cultivator sweeps are placed remotely relative to each other or as parts of combined working tools with spherical discs, chisels and parts, so the propagation a zone soil deformation during their operation at different depths speeds is studied by designers for calculation technological runs in order avoid clogging soil. (Research purpose) To determine dependence width loosening cultivator sweep on depth travel speed travel. (Materials methods) Studies have been conducted stubble background...
Scientific and educational nanosatellite of CubeSat 2U format launched by Belarusian State University October, 29 2018 is under use as Research/Educational lab for students, researchers global amateur radio community.
Development of Russian society puts forward new requirements for the quality training in higher educational institutions. It is necessary a short period institution not only to transfer student's important professional knowledge and skills, but also form ability willingness use them creatively. This issue especially challenging when preparing design students. Today, promising, popular dynamically developing profession designer demand almost all areas life. The increased individuality living...
At industrial enterprises, seaports, ships, more than 80 % of all electrical engineering equipment is asynchronous motors. In a number cases, motors operate with sharply variable load, in an aggressive environment; herewith they receive power from the network deviations quality indicators normative ones, which causes their high damageability. Turn circuits stator windings account for about 40 cases damage to insulation windings. Untimely detection initial moment appearance defects or...
Vibration of the working bodies decreases force traction resistance plough for ploughing soil. is spontaneous and forced. Spontaneous vibration comes from variable soil, forced requires add
The results of laboratory tests the angle and coefficient friction soil on steel surface in a state rest forced vibrations are given. studies were conducted department agricultural machinery Voronezh State Agrarian University. They used method measuring these parameters an inclined plane with produce bend. In quiescent was found to be φ = 0,548 radian, which corresponds f 0,61. data obtained as result average 10 repetitions, standard deviation σ 0,003 radian.
The yield of sugar beet depends not only on soil and climatic conditions, but also the quality distribution plants along sowing series these plants.The maximum is obtained with optimal value average interval between plants, all intervals should be same a coefficient variation close to zero.A computer program has been computed for relative yields, depending precision germination seeds.The harvest calculated in terms exclude influence weather conditions.For maximum, taken exact location number...
Abstract The aim of the study is to search for analytical dependence force resistance wedge on lifting angle in case working with wet soil, which does not crumble into fragments, but slides along form a continuous tape. Tillage tools can have front and rear sharpening angles. raises soil layer, this action most common tillage. corner seals bottom furrow, so it undesirable plows. To determine rational inclination entire surface under conditions an equation has been obtained, applicable if...
We investigate the problem of construction exact numerical solutions motion equations a spacecraft with low thrust engine, which realizes transfer between distant orbits in Newton central gravity field. Approximate solution classical mechanics space flight about maximal payload under given launching mass is constructed by averaging method. discussed variants determination on trajectories, move away not too much from trajectory averaged solution. One suggested shown for example interorbital...
Asynchronous motors work under drastic dusty conditions at industrial enterprises. As a consequence dust and moisture into the winding. The location where winding gets out of groove is subject to dynamic forces, it resulting in microcracks. result, conducting bridges are formed on frontal end amount current flowing through layer depends material its thickness. Studies this issue have not been conducted modern literature. task timely detection diagnosis natural aging insulation, becoming wet...
Asynchronous motors (AM) are the most common electrical consumers. The share of AM all power consumers operating at voltages up to 1000 V is 70% total number. main reason for electric machines service life reduction in severe environment pollution with dust accelerated aging insulation stator windings. In consequence fact that a number enterprises Ukraine changed from scheduled preventive maintenance repairs case emergency, timely detection abnormal conditions key trouble-free operation...
