ROTATING DYNAMIC ACCELEROMETER

A mass-spring system is rotated so that the sensitive direction of the accelerometer is periodically pointed in the direction of an acceleration to be measured. The rotation causes the acceleration to act on the mass in different relative directions to modulate the measurement of the acceleration at...

Beschreibung
Zusammenfassung:	A mass-spring system is rotated so that the sensitive direction of the accelerometer is periodically pointed in the direction of an acceleration to be measured. The rotation causes the acceleration to act on the mass in different relative directions to modulate the measurement of the acceleration at the rotational speed, and dynamic transducers sense the motion. With low noise bearings, sensitive transducers, and low noise level electronics, low levels of acceleration can be sensed. The same structural design can be equipped for sensing higher acceleration levels.
