Two stage vibration isolator

An vibration isolating system comprising:

• a passive mechanical system comprising:
• a damping assembly comprising:
• a housing having a first end, a second end, an inner surface, and a passage defined by the inner surface extending between the first and second ends;
• a first bellows disposed within the passage and having a first bellows end, a second bellows end, and a first bellows outer surface, the first bellows end coupled to the first end, the second bellows end having a first bellows end surface, and the first bellows outer surface and inner surface of the housing defining a first chamber having a first volume;
• a second bellows disposed within the passage and having a third bellows end, a fourth bellows end, a second bellows inner surface, and a second bellows outer surface, the third bellows end coupled to the second end, the second bellows inner surface defining a cavity therein, and the second bellows outer surface and inner surface of the housing defining a second chamber having a second volume;
• and
• a piston disposed within the passage, the piston having a shaft having a first section, a second section and a shaft outer surface, the first section at least partially disposed in the second chamber, the second section at least partially disposed outside of the second chamber and defining the passage with the inner surface of the housing, the passage in fluid communication between the first and second chambers, at least a portion of the shaft outer surface between the first and second sections coupled to the fourth bellows end, the piston configured to receive a first force to thereby move the piston through the passage to increase the first volume and decrease the second volume;
• a first resilient member coupled in series with the damping assembly;
• and
• a second resilient member coupled in parallel with the series combination of the damping assembly and the first resilient member;
• a support member coupled in series with the passive mechanical system;
• a viscoelastic mount coupled to the support member;
• and
• a motion limiter coupled to the support member such that the passive mechanical system transmits a force to the support member when the passive mechanical undergoes longitudinal displacement greater than a predetermined displacement.
