Isolation system for an inertial measurement unit

In one illustrative embodiment, an isolator (24) for an inertial measurement unit (IMU) (10) is provided that includes an inner ring (42) with an outer surface (47) and an outer ring (40) with an inner surface (49). The inner ring of the isolator may have a recessed portion (43) and the outer ring m...

Zusammenfassung:	In one illustrative embodiment, an isolator (24) for an inertial measurement unit (IMU) (10) is provided that includes an inner ring (42) with an outer surface (47) and an outer ring (40) with an inner surface (49). The inner ring of the isolator may have a recessed portion (43) and the outer ring may have a protruding portion (41), wherein the protruding portion is inlet-locked with at least part of the recessed portion to prevent excessive rotation of the inner ring relative to the outer ring during high rotational events. The isolator may also include an elastomer (44) position between at least a portion of the inner ring and at least a portion of the outer ring to provide enhanced vibration and/or shock isolation during operation of the IMU, and to provide dampening of shock events during bottoming out of isolator during high shock events.
