Abstract

Squeeze film dampers which have become an extremely important component in any high speed turbomachinery needs a careful indepth study from the point of view of the support characteristics. Cylindrical type of squeeze film dampers which have become very popular from the point of view of their capability for providing; static stiffness are being evaluated in terms of quantitative value of static stiffness in a rig built for the purpose. The details of the versatile static test rig facilitating the loading of the damper ring upto 5000 - N in the hearing plane, the related instrumentation, and the experiments carried out are discussed in this document. The static stiffness of particular damper ring was obtained using the test set up.
