The limit state criteria for a mining shovel mechanical equipment that contains the faults of rotor imbalance-type are studied in article. On bases statistical analysis failures, it is demonstrated imbalance prevailing reason their accident-caused failures. three-year monitoring supporting elements vibrating activity vibratory norms electrical rotors take into account service condition substant...

An important generally recognized factor in improving the quality of cultivation recent years is elastic fastening working organs. It believed that bodies fixed with struts make intense vibrations, which leads to an improvement soil crumbling and a decrease traction resistance similar vibrations vibrator. However, paws on rack when receive deviation from set processing depth by 10-15% more than...

I t has been pointed out by Loeb 1 that our orientation in space is determined mainly by three groups of tropistic influences; namely, light, gravitation, and contact. Light and gravitation cause the orientation of organisms through effects upon muscle tonus. When the lines of force strike the animal obliquely, as for example, when light rays fall unequally on 1:he two eyes, the unequal stimula...

India is an agricultural nation where 70% of the people depend on successful agriculture. However, as population grows, farms are distributed among families; a result, average Indian farmer holds just two acres land. The system addresses innovative idea Joystick based in all farming systems. By implementing this project, we can eliminate many difficulties runs solar energy, which cleanest energ...

Carved turns with alpine skis are investigated. During the movement of a ski, snow is loaded and unloaded. Compacted snow is not elastic, i.e. deformations remain. Such effects are modeled by a hypoplastic constitutive equation. During a turn the shovel digs into the snow and the tail maintains nearly the same penetration depth as the part under maximum load. This results in a higher resistance...
