Notes:
Forced vibrations can lead to an irreparable damage of a blade array. Devices called “underplatformdamper” that dissipate the vibration energy are employed in order to reduce blade vibrationamplitude. The present paper deals with the design of the underplatform damper. A numerical codeto calculate the forced response of a blade array with dampers has been previously purposelydeveloped. A method is here proposed for the estimation of the unknown contact parametersdemanded by the code. The computation results are here validated by means of comparison withexperimental results on a static test rig. Three dampers with different shape are tested
