CHEESE ON TOAST!!
Typically the automotive industry makes extensive use of viscoelastic damping materials to address structure-borne vibration and radiated noise from body panels. Such damping materials are bonded to the base metal. To fully characterise the performance of such composite systems one would traditionally measure the bending properties of a carrier sample plate and then measure it again with the damping material applied.
At ASDEC we can do that easily with our Laser Vibrometry system and because we use lasers we don’t apply any mass loading to the samples whilst we measure them. This means that we can measure pretty much any material.
To demonstrate that we characterised the bending properties of toast and were able to show how a layer of melted cheese effectively damped the toast.
