Abstract

A rotational accelerometer using piezoelectric material, preferably quartz, in a shear orientation. Piezoplates (13, 23) and conducting seismic masses (14, 24), each having bores therethrough, are bolted to posts (12, 22) that are symmetrically mounted to a body (9) in such a manner that the bolt passes through the piezoplates but does not make contact. The accelerometer can be assembled as a single-axis accelerometer by mounting a pair of posts symmetrically about the body along the measured axis; additionally, the accelerometer may be assembled as a double or triple axis accelerometer by symmetrically mounting additional pairs of posts to the body. The total weight of the seismic masses and the crystals of the shear-type accelerometer halves should be equal. The invention sets forth a novel rotational accelerometer that reduces or eliminates the need for signal-processing electronics.
