Viscoelastic Material
Let us first consider a spring of viscoelastic material which is usually modelled as a K-V system,
For such spring,

The EOM of a system with mass 'm' and isolator k*, subjected to a harmonic excitation x(t) could be written as
The transmissibility could be written as
Let us now obtain the transmissibility corresponding to two different types of isolating elements |
