Purpose of the development: Managed dynamic damper for reducing discrete component vibration machines, machines and equipment in the operating frequency unsteadiness.

Recommended application field: Can be applied when dealing with low-frequency vibration (1 Hz) units of autonomous mobile objects (ships, planes, road transport), as well as power and industrial equipment and systems in various fields of technology.

Technical characteristic: Frequency range, Hz - 100 Power consumption for the damper with operating weight of 10 kg, W - 60

The development stage readiness: Introduced in production

Technical and economic effect: The method of dynamic vibration damping is used in vibration isolation structure of dynamic vibration absorbers, vibration affecting the condition of the equipment. The most effective use of dampers in conjunction with vibration isolation. Devices can be mounted either on the object of protection in order to improve vibration characteristics or the intermediate platform in a two-stage vibration control system for reducing the flow of vibrational energy transmitted to the foundation. Managed damper provides local weakening of the vibrations at the point of attachment. Therefore, the vibration protection system used do6 dynamic dampers. Select the number of dampers and their places of attachment is carried out using a technique developed by taking into account the structural features and the vibration condition of the equipment. The automatic frequency control is made on the basis of modern microprocessor technology. Using high-Q allows the dampers 10-12 dB to reduce the vibration of objects, and in conjunction with the two-stage vibration isolation system allows 10-20 times (20-26 dB) to reduce the levels of vibrational energy transmitted to the supporting communications on the speed shafts. Thus, the total weight of the active vibration dampers is 1-2% by weight vibroaktivnosti equipment.

Description of the development:
()
The components of the device: - clamping the lid; - movable and stationary magnetic circuits; - bias winding; - elastic elements (slit diaphragm). Vibration damper attached to the object of protection by the cover. Payment fundamental harmonic vibration exposure is achieved through the use of vibrations of the moving part on the elastic elements. A system of movable and stationary magnetic circuits, bias winding is used to create additional electromagnetic rigidity. Thus, frequency control is performed by controlling the current in the bias winding. To extend the control range on magnetic pole made crushed.
