Importance of container geometry of an elastomer particulate damper called Enidamp™ into the damping of vibrations

Research testing has been conducted to development of an innovative damping treatment, called Enidamp™. This treatment can add considerable damping to a structure by leading a vibration through a rigid connection, to a set of elastomer particles, which behaves as a damper. It is of interest to study the parameters involved in this mechanism of energy dissipation and to achieve optimal performance of the Enidamp™ system. Particularly, this paper experimentally analyzes the importance of the container geometry which houses the elastomer particles. For this purpose, the fluidization point at which the elastomeric particles become optimally excited to maximize damping is found for different depths and widths of the Enidamp™ container keeping the volume constant. Important conclusions from this experiment guide future studies for prototype improvements.
