Ruselectronics holding has designed an eddy-current damper for extreme service conditions. The solution is based on permanent magnets, resistant to temperatures from –80 to +80 ˚С and protected against sand and soil. This damper may be used as part of special-purpose and military vehicles designed for operation in Arctic and desert conditions.
Operating principle of the eddy-current damper is based on a force interaction (damping) effect occurring between permanent magnets. The device is resistant to extreme temperatures, because it is free from oil and gas-oil fluids.
Traditional hydraulic design dampers become harder at low temperatures and oil overheating may occur at high temperatures. Moreover, sand may get in rubber seals of oil and gas-oil units resulting in their malfunction. While the eddy-current damper is tolerant to abrasive particle damage.
“The main benefits of the eddy-current dampers include simple and reliable design, no need for external power supply and operation control. New products can be used in military and special-purpose vehicles in northern and southern regions,” said Andrey Tchendarov, Deputy General Director of Technological Development, United Instrument-Making Corporation (management company of Ruselectronics holding).
