| Abstract [eng] |
A damper is a device that is mostly used to extinguish or prevent mechanical oscillations and vibrations that occur during the operation of machines as part of structural elements or in kinematic hinge mechanisms. They reduce the impact of these mechanisms and absorb most of the axial loads that occur due to the movement of the rod and piston. Magnetic dampers are used in the production and rewinding of: wires, cables, threads, in winding and knitting equipment; in the production of fishing line, winding wire, synthetic and natural threads and cord; in the paper, textile and packaging industry. The magnetic type of the damper has a stable torque regardless of the speed of rotation, does not change during stopping and acceleration, and is also not prone to slipping. Magnetic dampers. In this type of damper (see Fig. 1.), vibration damping occurs not only due to viscous friction in the throttle elements, but also due to the selective placement of magnets. This allows the reduction or increase in the force of resistance due to the interaction of magnetic poles, when opposite or identical poles meet, respectively. Effective selection of the configuration and location of the magnets can significantly vary the support force of the damper, in particular at the final stages of the "compression" and "expansion" modes.
