Vibration Isolators Made of Expanded Cork Agglomerate

The present work characterizes vibration isolators made of expanded cork agglomerate. Its dynamic characterization involved performing transmissibility tests for different static and dynamic loading conditions. The resulting transmissibility curves indicate how much vibration is transmitted through the isolator to its base at a given frequency. This study covered four mass density ranges and four block thicknesses. The tests were also performed under different conditions of strain to better understand its effect on the dynamic performance of the material and to assess whether it might be a limiting factor.
