ABSTRACT:
An integrated accelerometer includes features for minimizing the effects of foreseeable operational stresses. The accelerometer is of a type that includes a planar support base having an internal aperture for accommodating a hinged strut and limit stops for minimizing the travel of the shadow paddle portion of the strut. The limit stops are fabricated of material of suitable spring constant to provide an appropriate degree of "give" without degrading instrument performance or accuracy. Two-piece arrangements sandwich the hinges, thereby limiting flexure to an acceptable range. The predictable mechanical stresses resulting, for example, from thermal coefficient mismatches between the materials of the torquer coil and the strut are minimized by the use of a spacer intermediate the base and the coil. The spacer, fabricated of material whose thermal coefficient closely matches that of the pendulous mass is generally circular, and includes diametrically-opposed prongs on the upper and lower edges thereof, such arrangements of prongs being staggered by ninety degrees.
