Filed:
Aug 26, 1992
Appl. No.:
7/936092
Inventors:
John M. Barry - Lexington MA

Thomas E. Shelvey - Westford MA
Assignee:
The Charles Stark Draper Laboratory, Inc. - Cambridge MA
International Classification:

Abstract:
A flexure for an accelerometer includes an inner hub; an outer rim spaced from the inner hub; one of the hub and rim being mounted to the accelerometer body and the other to the proof mass of the accelerometer; at least three curved tapered beams extending between the rim and the hub with the widest beam portion proximate the rim, for flexibly supporting the proof mass and enabling relative rotational relief between the hub and rim for preventing nonlinear stretching of the beams.
