ASYMMETRIC FLEXURE FOR PENDULOUS ACCELEROMETER An improved accelerometer of the type that includes a proof mass (34, 24, 164, 170) suspended from a support (32, 172) by one or more flexures (36, 174), such that the proof mass can pivot with respect to the support about a hinge axis (HA). The proof mass includes a paddle (34, 164) attached to the flexures, the paddle having first (166) and second (168) paddle surfaces. The coil (170) is mounted on the first paddle surface, and the accelerometer includes a stator (42, 162) for mounting the support and for forming a magnetic circuit with the coil. The improvement comprises positioning the flexures such that a plane containing the hinge axis and the center of mass (180) of the proof mass is parallel to one of the paddle surfaces, and is closer to one paddle surface than to the other paddle surface. In a preferred arrangement, the plane containing the hinge axis and the center of mass is approximately coplanar with one of the paddle surfaces and with the flexures. |
