Abstract
A damping mechanism suitable for use with a vibrating beam accelerometer comprising a piezoelectric block mounted between the vibrating beam force transducer and the pendulum of the instrument. The proof mass, or pendulum, is mounted for pendulous motion about a pair of hinge means. Vibration of the instrument causes opposite charges to appear on electrodes which are on two opposite faces of the block. These charged electrodes are connected to each other by a resistor and so a current will flow through the resistance to neutralize the charge. The resistor will then dissipate the vibration energy as heat. This energy dissipation is effectively damping.
