ABSTRACT:
A mount for a vibration structure includes a ring having a flexural portion defining an arcuate mounting surface terminating at a free distal end and secured to an arcuate bearing surface on a flange of the vibration structure in coaxial bearing engagement therewith, the flexural portion having a radial stop surface spaced from the distal end and contacting an end surface of the vibration structure flange. Attachment structure on the mounting ring is adapted for attachment to an associated support. The flexural portion is resonant at the resonant frequency of the vibration structure and is shaped and dimensioned for flexing sufficient to accommodate movement of the bearing surface at resonance.
