Abstract:
A method and apparatus for relieving thermal stress on the flexures of an accelerometer, particularly a quartz accelerometer, caused by the difference in the coefficient of expansion of a bonding adhesive or a sealant placed over a bonding pad to protect or attach the ends of the torque coil and the coefficient of expansion of the quartz. The strain is relieved by supporting the bonding pads on flexible attachments to prevent thermal stress from being transferred into the pendulum and flexures.

Abstract:
An accelerometer that includes a proof mass assembly comprising a paddle flexurally mounted to a support, a sensing circuit for detecting movement of the paddle, and a force rebalance system. The sensing circuit includes a capacitor plate positioned on a surface of the paddle. The proof mass assembly is clamped between upper and lower mounting pieces positioned on opposite sides of the proof mass assembly from one another. One or more fasteners extend between the upper and lower mounting pieces through the proof mass assembly. The support is shaped so as to form openings through which the fasteners pass, such that the support isolates each fastener from the paddle. This arrangement isolates the paddle from a source of contamination, provides for a more evenly distributed clamping force, and minimizes distortion of the mounting pieces. The fastener openings in the support may be shaped so as to limit movement of the paddle towards the flexures.
