DAMPER WITH A PLURALITY OF SQUEEZE-FILM DAMPERS ACTING IN PARALLEL

摘要

A damper having a plurality of fluidic squeeze-film dampers acting in parallel. The damper of the present invention includes a plurality of fluidic squeeze-film dampers, each including a gap filled with viscous fluid provided between first and second damping elements. Each of the plurality of fluidic squeeze dampers creates an individual damping effect, which in the aggregate, act in parallel. As a result, the damper achieves (i) very high damping and stiffness over a relatively short stroke, (ii) compact size and (iii) adjustability to a limited degree by adjusting the gaps.
