Abstract
This paper describes an experimental method to define the damping coefficient using a specially designed test device. The damping coefficient is defined through the transient analysis. Impact data is recorded using a sensitive acceleration sensor mounted on the device where a test object is placed – a squeeze film damper with an elastic ring, the design of which is often used in aircraft engine rotor supports.
