Ultra-light weight undamped tuned dynamic absorber for cryogenically cooled infrared electro-optic payload

摘要

Attenuation of tonal cryocooler induced vibration in infrared electro-optical payloads may be achieved by using of Tuned Dynamic Absorber (TDA) which is, generally speaking, a passive, weakly damped mass spring system the resonant frequency of which is precisely matched with the driving frequency.
