The requirements for an isolation system of platform generally include :

  1. isolation of vibrations
  2. isolation of shock / survivability
  3. acoustic silence

 

schock isolation

 

 

 

 

 

 

The particular specifications may be :

  1. long dispalcement for an optimal response to shock
  2. a relatively low natural frequency to isolate the vibrations, even under high frequencies input
  3. an acoustic attenuation at high frequencies
  4. high damping under shoch, low damping for acosutics and vibration control
  5. a high static capacity due to mass of the equipment
  6. minimum change of the dynamic stiffness
