signal intensity vs material thickness
signal intensity vs material thickness
(OP)
does anyone know what's the relationship between vibration signal transmissibility/intensity versus material thickness? Is there any literature regarding this subject?
the reason for this is that recently i have a bearing failure on a machine whereby the bearing housing is quite thick. the vibration level obtained was low. i suspect the thickness of the bearing housing could weaken the vibration signal, but i need literature to validate my finding.
Thanks

RE: signal intensity vs material thickness
However, that is the very simplest case. These days most people would use an FEA model to work back to an excitation force, I suspect.
