Abstract: Abstract 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… read more here.

Abstract: Abstract In this paper the effectiveness of a mass-damper dynamic absorber in preventing rigid blocks from overturning is investigated. The mass-damper is modelled as a pendulum, hinged at the top of the block, with the… read more here.
