Linear motors are designed for use in electric drivers of the loading systems of aircraft simulators as non-contact actuating force providers. Their functional purpose is conversion of the electric power of direct current into mechanical energy of the translatory motion of thrust of the system for aircraft simulators' loading to create the corresponding force on working levers.
We developed and put in operation single- and two-phase power motors from 30 to 180 kgf.
It is designed to control two brushless executive motors and is combined of two power electronic commutators with microprocessor control and provides separate or compatible starting, established mode of operation, braking and stopping of executive motors on the signals of limit switches and operator.
Surface strengthening of the details of rotation bodies forms by vibration and centrifugal processing by increasing the hardness of metal and redistribution of residual stresses in it provides increased the longevity by 2-2.5 times of airplanes wheels and vehicles with discs from the magnesium and aluminum alloys. Alongside with increased reliability of disks and drums this strengthening technology allows to reduce the weight of these parts by 15-20% that improves the dynamic characteristics of cars, reliability and security of transport transportations.
The developed technology basics of vibration and centrifugal strengthening of long-length details that ensures high level of deformation energy, capable of riveting the surface layers of steel details at a depth of 0.2-0.25mm.
Strengthening of casing tubes, high pressure tubes, internal and external surfaces by vibration and centrifugal processing and allows not only to increase the strength of these details, but also to reduce theirmaterial capacity to 15-20%.
The developed technology basics involves surface strengthening of drilling pumps by vibration and centrifugal processing with simultaneous formation of carbide layer resistant to abrasive wear on them. At the same time increased hardness of metal on the working surfaces of pump sleeves in combination with the formation of wear resistant layer on them, combination of themprovides positive synergistic effect, by 1.5-2 times increases the longevity of expensive drilling pumps.
A centrifugal vibration technology basics has been created for strengthening of internal surfaces of lengthy parts, which provides increased hardness of the metal in the surface layers of the inner surface of gun barrels and forming in them favorable stress of compression.
The proposed strengthening technology is appropriate to the usage for large-calibre artillery and tank guns, drilling and casing pipes, high pressure pipes.
There is no technology analogue of centrifugal vibration strengthening of the internal surfaces of gun barrels in the world.
This is a high-performance, economically feasible and environmentally friendly technology of electrochemical processing of the secondary raw materials of tungsten (obsolete armour-piercing discarding sabots (WC-Ni), used bits of quick-cutting tools (WC-Co) obtaining the commodity sulfates of tungsten oxide, ammonium paratungstate and nickel or cobalt.
Cooling and lubricating mixtures that contain polymers are used for cutting, honing, grinding, finishing and super finishing processing of metals that are difficult to process and alloys. They are made from synthetic polymeric latex. They allow us to intensify the metal processing with a reduction in energy costs.
Miniature thin-film thermoelectric generators on the basis of A2VB3VI-, AIVBVI-compounds and other semiconducting materials directly transform waste heat into electrical power. The use of advanced thin-film technology at manufacturing ensures their small-size and high power density at the output.
