Asymmetric flexure for pendulous accelerometer
Patent
·
OSTI ID:6800582
This patent describes an improvement in an accelerometer for measuring acceleration along a sensing axis. The accelerometer comprising a proof mass suspended form a support by one or more flexures such that the proof mass can pivot with respect to the support about a hinge axis, the proof mass comprising a paddle attached to the flexures, the paddle having first and second paddle surfaces and a coil mounted on the first paddle surface. The paddle surfaces being planar and parallel to one another. The accelerometer further comprising means for mounting the support and means for forming a magnetic circuit with the coil such that the proof mass can be maintained in a null position.
