Abstract
A sensor assembly includes a frame defining a sensor axis having opposing endplates with axially extending supports. The opposing endplates are connected by a pair of axially extending side beams. A suspended mass is within an interior of the frame suspended from the supports of the frame. A plurality of piezoelectric material layers are operatively connected to sides of respective spacers opposite the frame to damp vibrations of the suspended mass.
Claims13
A sensor assembly comprising:
- a frame;
- a suspended mass within an interior of the frame defining a sensor axis;
- and
- a piezoelectric material layer operatively connected to the frame to damp vibrations of the suspended mass, wherein the piezoelectric material layer is a macro-fiber composite (MFC) piezoelectric material layer, wherein the frame includes inwardly extending supports to which the suspended mass is suspended from.
