Virtual Prototyping of a Dynamic Vibration Absorber for the Vibration Control of a Frame Structure

The control of structural vibrations in the mechanical, aerospace, and civil fields is becoming increasingly important in recent years. A fundamental problem in the design of civil and industrial structures is the high vibratory level that characterizes them due to environmental factors, such as high windiness or high sensitivity to seismic phenomena of the areas in which the structures are located. Particular attention is paid to non-dissipative systems, known as dynamic absorbers, used to modify the behavior of buildings in seismic territories or in areas with high winds. The purpose of these devices is to absorb a portion of the incoming mechanical energy in order to decrease the demand for energy that the structure must dissipate, thereby reducing its damage. The aim of this paper is, therefore, to analyze different types and design methodologies of dynamic absorbers and any fields of their application in order to highlight their contribution to dynamic dampening of mechanical vibrations.
