The degradation of vibration isolat

The degradation of vibration isolation performance due to a damper can be avoided by isolating the damper from the ground vibration by means of another mechanical filter as shown in figure 2.10. This technique is called flexible damping. Although the additional spring introduces another resonance to the system, the amplitude of the transfer function falls in proportion to f −2 at high frequencies as in the case without dissipation (see the plots in figure 2.10).
