1. A method for optimizing a frequency-shifting isolator system, the steps comprising:
- determining a desired impact absorption envelope from a displacement-natural frequency requirement of the frequency-shifting isolator system;
defining a set of structural system requirements within the desired impact absorption envelope;
selecting at least one geometry for the frequency shifting isolator system that conforms to the set of structural system requirements; and
selecting a desired structural material formed in the at least one geometry, the material configured to shift frequencies at a plurality of displacements upon impact within the desired impact absorption envelope, such that the frequency shifts occur in response to one or more of the plurality of displacements.

Abstract
The present invention provides a method for designing a frequency-shifting isolator system that includes selecting, an impact absorption envelope; a geometry for the isolator mount system; and an elastomeric dampening material formed in the selected geometry. The isolator mount system is preferably configured to shift frequencies at predetermined displacements upon impact, at or before the system attains resonance.
