Abstract

We study the damping efficiency of torsional vibrations of a body using a dynamic vibration damper containing a system of successive impactor pairs with magnets as colliding elements. Dimensionless essentially nonlinear differential equations of motion of the protected body and magnetic elements are obtained. The influence of the designed parameter selection of the vibration damper on the vibrations of the carrying body is considered. The features of damper tuning in a wide vibration damping band mode are described. The optimal variant of damper tuning with the most effective damping of body vibrations is established.
