Vibration Stimulation by Imbalance of Rotary Solids

The microscopic and macroscopic inhomogeneity of all solids causes an unequal distribution of the masses. If the solid accelerates, then different forces affect it depending on the mass distribution. If the body is to follow a certain movement, then resulting forces deviating by the direction of motion must be compensated by reactive forces. 

If it concerns a rotation in the case of the movement of the body, then its inhomogeneity leads to a so-called imbalance. Depending on the number of revolutions n = tS/2ir and the mass distribution asymmetrical to the rotation axis 

the resulting forces Fg perpendicular to the rotation axis act over the entire lengths of the component that rotate with the solids  

The counterforce necessary for the compensation is to be apphed by the carrying components of the aggregate. If the compensation takes place statically, then the forces proceeding from the rotating component are compensated by an acceleration of the carrier construction  

With the increasing mass of the carrier construction, the acceleration acting on the aggregate is reduced. Here one speaks of the so-called inertia of the carrier elements.
