VIBRATION ACTIVATORS IN THE CONSTRUCTION TECHNOLOGY
Abstract
The distinctive advantage of the considered vibration exciters from the point of view of machine vibration isolation is a balance of oscillating masses and, as a consequence, reduction of dynamic loads on external objects. The paper presents description of the design; the process of interaction with the treated medium revealing the following property of the balanced eccentric vibration activators: static (dynamic) balancing of the system, set in the air medium, is not affected when dipping the vibration activator into the mix.
The paper presents methods of balancing adjustment of vibration activators at the design stage and examples of calculations.
