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.
Claims8
A flexure for an accelerometer comprising:
- an inner hub;
- an outer rim spaced from said inner hub;
- and
- at least three curved, tapered beams extending between said rim and said hub with the widest beam portion proximate said rim for flexibly supporting the proof mass of said accelerometer and enabling relative rotational relief between said hub and rim for preventing non-linear stretching of the beams;
- said beams being tapered along a portion of their lengths extending from said hub and said rim.
