COMPACT VIBRATION ISOLATION SYSTEM FOR AN INERTIAL SENSOR ASSEMBLY

Disclosed is a compact vibration isolation system (120) for mounting an inertial sensor assembly (ISA) (122) to an Inertial Measurement Unit (IMU) housing (136). The housing (136) is mounted to a support (155) that is subjected to shock and vibration. The vibration isolator assembly (120) includes a...

Zusammenfassung:	Disclosed is a compact vibration isolation system (120) for mounting an inertial sensor assembly (ISA) (122) to an Inertial Measurement Unit (IMU) housing (136). The housing (136) is mounted to a support (155) that is subjected to shock and vibration. The vibration isolator assembly (120) includes a ring shaped elastomeric member (126) laminated between a ring shaped inner member (130) and a ring shaped outer member (128). The inner member (130) is securely mounted to the ISA (122), and the outer member (128 ) is mounted to a support (137) of the IMU housing (136). Because of the compa ct size of this system (120), the IMU housing (136) contains and protects the elastomeric member (126) from potential contamination and damage, as well as eliminates the need for delicate mechanical and electrical interfaces. The elastomeric member (126) of the system (120) isolates the ISA (122) from shock, vibration, and acoustic energy that may otherwise be transmitted from the support (155) to the ISA (122).
