Abstract: “In this study, Foam Filled Fluid (FFFluid) technology was investigated for the design of a novel vibration isolator, which is referred to as an FFFluid isolator. This technology relies on the utilisation of both the strain of foam capsules and fluid motion for reducing unwanted vibrations. Such an FFFluid isolator basically consists of compressible elastic particles of foam, mixed with an incompressible fluid while this mixture is contained in a controlled volume. When the FFFluid isolator is affected by vibrations, energy is absorbed due to the elastic strain of the foam. As the foam strain also enables movement of the fluid, this contributes to further energy absorption due swirling and the viscous effect of the fluid. The packaging could also contribute to attenuate vibration through the generated friction between the piston and the cylinder used to contain the FFFluid. Former studies showed that promising performances in reducing unwanted forces can be achieved with shock absorbing”
